How to Make Probiotic Ginger Beer - a naturally fermented probiotic-rich beverage that you can brew at home using minimal equipment! | TheRoastedRoot.net

Disclaimer: brewing probiotic beverages at home can be risky. When fermenting probiotc foods and beverages, use caution. Always use sanitized tools and when in doubt, throw it out! If you notice any strange smells or mold, be sure to discard the whole batch.

Many moons ago, I wrote a cookbook called Delicious Probiotic Drinks. This cookbook is focused entirely on making probiotic-rich beverages such as kombucha, kefir, ginger beer, fermented vegetable juice, and more, at home.

My favorite of all the fermented beverages to make is ginger beer. First and foremost, it is magnificent tasting.

Secondly, it is CHALLENGING.

Perhaps the most challenging and unforgiving of all the fermented drinks.

And for that reason, the most rewarding.

For those of you who have been around this site for a long time, you may remember my easy tutorial on How to Make Ginger Beer.

This is the goof-proof method that works each and every time and does not require much time or attention.

This version of probiotic ginger beer is different. It involves preparing a โ€œginger bugโ€ (or ginger starter) from scratch.

How does that work?

Probiotics and yeast are naturally occurring everywhere. They are in our fruit and vegetables and are also present in the air. Giving these probiotics and yeast optimal conditions to grow and reproduce results in fermentation.

Youโ€™re already familiar with this concept, as it is the same process for creating yogurt, cheese, beer, wine, pickles, prosciutto (and other fermented meats), etc.

Applying this idea to fresh ginger is how we create a ginger starter, which is then used to make ginger beer.

Donโ€™t worryโ€ฆIโ€™ll go over how to make a ginger starter in excruciating detail later on in this post. First, letโ€™s cover some basics.

WHAT IS GINGER BEER?

Ginger beer is a naturally fizzy beverage with a sweet and spicy bite. Grated ginger is fermented in sugar water and lemon juice, allowing the natural yeasts in ginger to feed and multiply, creating a probiotic beverage.

While ginger beer is a sweet, spicy, delicious beverage all on its own, it is famous for its role in cocktails, particularly the Dark & Stormy cocktail, a mixture of ginger beer and rum, garnished with a slice of lime.

WHAT IS THE DIFFERENCE BETWEEN GINGER BEER AND GINGER ALE?

The phrases, โ€œginger beerโ€ and โ€œginger aleโ€ are typically used interchangeably, but there is a difference between the two beverages. Ginger beer is fermented for up to 2 or 3 weeks using a โ€œginger bug,โ€ where ginger ale is more of a ginger flavored soda.

While there are ginger ale beverages made with real ginger, most ginger ales are simply carbonated water with ginger flavor and sugar. In this sense, ginger ale does not go through the same fermentation process that ginger beer does.

METHODS FOR MAKING GINGER BEER

There are multiple ways to make ginger beer. Here are three of the most common methods:

  • Non-probiotic ginger soda/ale: For those who arenโ€™t concerned about the probiotic benefit of fermented ginger beer, you can simply combine ginger simple syrup (made with ginger and sugar) with soda water and achieve a great-tasting homemade beverage. This version contains no probiotics and is basically fancy soda.
  • Quick and Easy Ginger Beer with some probiotic benefits: This fast method uses bread yeast for fermentation and requires only two days to complete. For this version, read my blog post on How to Make Ginger Beer. This version is not as probiotic rich, but is still lower in sugar than regular soda.
  • Authentic Probiotic Ginger Beer – a health elixir: The authentic method for making fermented ginger beer is outlined in this post. It uses a probiotic-rich โ€œginger bugโ€ (or ginger starter) which you make yourself at home. Like most things in life, the authentic version takes much longer than the easy version, but also yields great results. This version can take between 2 and 3 weeks to complete.

HEALTH BENEFITS OF GINGER BEER

Fermented ginger beer has a great deal of health benefits and is commonly used to ease upset stomach, nausea or diarrhea.

Ginger is an anti-inflammatory, which can help with migraines, and studies show fresh ginger prevents and fights several types of cancer cells including breast, colon, ovarian, prostate, and lung cancer.

Ginger is also known for cleansing the body of toxic chemicals, easing menstrual cramps, and much more!

The probiotics and yeast that grow during the fermentation process help colonize your gut with good bacteria, which helps boost immunity, fight disease, and promotes overall health.

HOW TO MAKE FERMENTED PROBIOTIC GINGER BEER

Fermented probiotic ginger beer requires a three-step process.

Step 1: Make a โ€œginger bugโ€ or starter using fresh ginger, water, sugar and lemon juice. This starter is used to brew a batch of ginger beer (Step 2). This can take 1 to 2 weeks to complete (depending on the temperature of your home and how active your culture decides to be).

Step 2: Brew a large batch of ginger beer using the โ€œginger bug.” You could compare this process to making a batch of sourdough bread dough using sourdough starter. This process takes about 1 to 3 weeks, depending on how active your ginger bug is and how warm your home is.

Step 3: Bottle the ginger beer and allow it to ferment further. Once the beverage becomes effervescent (fizzy/probiotic-rich), bottle it and allow it to sit for โ€œsecondary fermentationโ€ (more on this below). This process takes about 2 to 5 days.

You Will Need:

  1. 1-quart glass jar or jug 
  2. Cheesecloth 
  3. Stretchy rubber band
  4. 1-gallon glass jugย 
  5. Flip-Cap Bottles 
  6. Fresh ginger
  7. Organic Cane Sugar
  8. 2 to 4 Lemons

Ingredients for the “Ginger Bug:”

  • 1-inch nub fresh ginger, peeled and grated, plus more for feeding the starter
  • 1 tablespoon raw organic sugar, plus more for growing the starter
  • 2 cups water

Instructions for the Ginger Bug / Ginger Starter:

Peel and grate a 1-inch nub of fresh ginger (about 1 tablespoon).

Box grater on a plate with fresh ginger grated on it

Add the grated ginger, 1 tablespoon of sugar, and two cups of filtered water or spring water (non-chlorinated) to the jar and stir (a 1-quart jar works great).

Cover the jar with a cheesecloth or towel. Secure the cloth around the jar with a rubber band. This keeps insects away from the starter.

Allow jar to sit in a warm, dark place for 24 hours. The optimal temperature for preparing the ginger starter and brewing ginger beer is between 70 and 85 degrees.

If your house stays cool, find the warmest spot in your home to place the ginger starter. This process activates the probiotics and yeast that are in the ginger and allows them to begin reproducing.

Feed the colony – Once a day for one week, add one teaspoon of sugar and one teaspoon of grated fresh ginger to the jar and stir well.

This ensures your ginger starter stays fed and grows, similar to sourdough starter. Stir a couple of times per day.

During this process, natural yeasts are released and create a white substance at the bottom of the jar. This is where the probiotics come from.

After about 3 to 5 days (perhaps longer if your house is very cold), the liquid will begin bubbling when you stir it. Once you can see and hear bubbles without touching the jar, your ginger bug is ready to be used. This will usually take 7 to 10 days in a warm (70 to 80 degrees F) house, but longer in a cool house.

To expedite the process, wrap the ginger starter jar in a heat blanket or an insulated blanket to keep it warm. If after 7 days, your ginger bug is still not bubbling, continue adding a teaspoon of sugar and ginger until it does. Have patience, friend!

In some cases, folks have gotten bubbles within only a few days of beginning their starter. While this is unusual, it is a sign the starter is ready! As soon as you see the bubbles rushing from the bottom to the top, you’re ready to go.

Use the liquid from ginger starter to make ginger beer (instructions below).

You can continue adding water, ginger, and sugar to the starter and to use it for multiple batches of ginger beer. In this sense, you can treat your ginger starter the same way one would treat sourdough starter and keep it alive.

Note: If you ever see mold floating on top of the starter liquid, discard the starter and make a new one.

Ingredients for the Ginger Beer:

  • 1 cup ginger starter (see above)
  • 1 scant gallon of filtered spring or well water
  • 1 1/4 cups organic cane sugar 
  • 1/2 cup fresh lemon juice
  • 1/3 cup fresh ginger, grated

Instructions for 1 Gallon of Probiotic Ginger Beer:

Fill a gallon-sized jug most of the way up with spring or well water (do not use water from the tap unless your house runs on a well). This water should be room temperature or slightly warmer (aim for 70 to 80 degrees).

Add one cup the the ginger starter, along with 1 1/4 cups of sugar, 1/2 cup of lemon juice, and 1/3 cup of grated ginger. Stir very well.

Cover the jug with a cheesecloth or towel bound by a rubber band and put it in a warm, dark place at room temperature for 8 to 10 days. Mine takes 8 days, even in a very warm (80โฐF +) house.

Taste-test the mixture periodically to see if more sugar needs to be added (the natural probiotics will eat the sugar so if the beverage ever loses all of its sweetness, add a little more sugar (no more than 2 tablespoons at a time), but be careful to not overload the probiotics, as they can die when given too much sugar.

Stir the mixture once or twice a day. You will notice a white substance forming around the ginger at the bottom of the jug.

This is the natural yeasts coming out of the ginger โ€“ itโ€™s a good sign! There will also be large bubbles that form on the surface of the liquid.

The ginger beer is ready when the substance becomes bubbly when stirred (similar to when youโ€™re making the ginger starter).

Once the ginger beer is ready, give it a taste test. If it doesnโ€™t taste sweet, add additional sugar and ginger because once you bottle the brew, it goes through secondary fermentation and the probiotics continue to need to eat sugar. 

At this point, your options are to either bottle the ginger beer as-is or flavor it prior to bottling it. See information on Secondary Fermentation and flavoring options below.

Pour the liquid (including the ginger pulp) into sealable bottles and set them in a dark room for 2 to 4 days. This process makes the ginger beer very fizzy.

The warmer the room, the faster the beverage gets fizzy, so open a bottle every day or so to check the fizz and level of sweetness.

Both the fizz and sweetness is up to your taste but be very careful to not allow the bottles to sit for too long because they most definitely will explode.

Place bottles in the refrigerator to calm the fermentation process. Note that the ginger beer will continue to ferment in the refrigerator, so try to consume the beverage within a few days after secondary fermentation is complete for best results.

Leaving it in the refrigerator for longer than a week will result in a โ€œdrierโ€, less sweet ginger beer.

You can now brew another batch of ginger beer using the ginger starter you have been feeding. Because your ginger starter is now more mature, it will take a little less time to brew your second batch.

SECONDARY FERMENTATION

Once ginger beer is finished with its primary fermentation, you may add additional sugar and/or ingredients (see “Flavoring Ginger Beer” section below) to flavor it and allow it to go through a secondary fermentation.

The purpose of secondary fermentation is threefold: To achieve a fizzy beverage (it will get just as fizzy, if not fizzier than soda!), to make the drink even more probiotic-rich, and to give it delicious flavor.

FLAVORING GINGER BEER

Ginger beer is perhaps the easiest probiotic drinks to flavor because just about any type of fruit and/or herb goes wonderfully with ginger.

The fact that there is already a great deal of sweet and spicy flavor in ginger beer provides a wonderful canvas for incorporating other sweet, sour, tart or creamy flavors.

In this way, the added ingredients are typically what one tastes first when drinking the ginger beer, with the spicy ginger coming through at the finish.

You have a few options for adding ingredients for secondary fermentation. You can add fresh fruit juice, a homemade simple syrup infused with any flavor you like, or a fruit/herb sauce (similar concept to simple syrup).

If you’re adding fruit juice, simply add 1/4 cup to each glass bottle before filling them the rest of the way up with ginger beer. Secure the lids tightly and allow them to sit for 2 days. Immediately transfer to the refrigerator to slow the fermentation process.

Getting creative with fruit and herb combinations is brilliant when it comes to this drink and you are virtually guaranteed to end up with a delicious probiotic drink!

To make flavor ginger beer, choose your fresh fruit and/or fresh herbs.

Combine 2 cups of fresh fruit with ยฝ cup cane sugar and 1/3 cup water in a saucepan (Note: if youโ€™re adding fresh herbs, do so here as well).

Bring to a full boil and cook until the fruit has softened. Allow mixture to cool completely. Once cool, divide it between the bottles you are using to bottle the ginger beer.

Fill the bottles the rest of the way up with ginger beer, seal tightly, and allow bottles to sit at room temperature for 2 days to undergo secondary fermentation. Transfer the bottles of ginger beer to the refrigerator and chill.

Flavored Ginger Beer Options:

Here are some of my favorite flavor combinations for ginger beer:

  • Blackberry Sage (2 cups blackberries, 1/2 cup sugar, 1/3 cup fresh sage, packed)
  • Grapefruit Rosemary (1 cup fresh grapefruit juice, 2/3 cup sugar, 3 sprigs rosemary)
  • Coconut Basil (1 can full-fat coconut milk, 1/2 cup sugar, 1/2 cup fresh basil, packed)
  • Blood Orange (1 cup fresh blood orange juice, 1/2 cup sugar)
  • Raspberry Mint (2 cups fresh raspberries, 1/2 cup sugar, 1/2 cup fresh mint)

SHELF LIFE OF GINGER BEER

How long does homemade ginger beer last?

When properly sealed in bottles, plain ginger beer can last for up to one month in the refrigerator. For best results, drink within 2 weeks of brewing.

When ingredients such as fruit, are added to ginger beer, consume within 1 week for best results and keep in the refrigerator for up to 2 weeks. While ginger beer can last even longer than this, it is best to err on the safe side when it comes to probiotics.

A NOTE OF CAUTION

As is always the case with probiotic beverage, be cautious when opening a bottle after secondary fermentation as pressure builds and the drink will be fizzy. Never point a bottle at your face (or at any other person) while opening, and never hand a bottle to a child to open.

TROUBLESHOOTING

If it seems like either your ginger starter or ginger beer is taking a long time to come to life (get bubbly), donโ€™t worry. This is likely the result of the temperature of your home, and it may just take some extra time.

As mentioned previously, if you want to expedite the process, wrap the jar in a heating pad and set it to a low temperature to keep the starter warm.

On the flipside, in rare cases, a ginger starter may be ready after only a few days. As long as bubbles are flowing from the bottom to the top, that is a sign the starter is rich in probiotics and is ready to be put to use.

Like many probiotic beverages, ginger beer is one of those that seems to be doing nothing for quite some time and then all of a sudden, itโ€™s working.

At the end of secondary fermentation, if your ginger beer too dry (not sweet and very fizzy), this is because the yeast consumed all of the sugar that was in the bottle, leaving very little sweetness for you.

Some people prefer drier ginger beer, but if you prefer it to be on the sweet side, simply make sure you add additional sugar (either cane sugar, fruit, or juice) prior to bottling your next batch.

Did you pop open a bottle of ginger beer after 3 days of secondary fermentation and it wasnโ€™t fizzy and it still tasted sweet?  If this is the case, your ginger beer still contains residual sugar that needs to get eaten up by the probiotics. This is okay!

Simply leave the remaining bottles (if any) at room temperature to continue secondary fermentation. Because there was plenty of sugar in the beverage prior to bottling, it will simply take an additional day or two for the probiotics to consume the sugar and for the beverage to become fizzy.

How to Prevent Flat Ginger Beer:

To prevent flat ginger beer, be sure there are small bubbles that rise from the bottom to the top of the liquid prior to bottling it for secondary fermentation, as this is a sign of probiotic activity.  Keep in mind that even if your ginger beer does not get fizzy, it is still full of probiotics and is great for you!

Wondering if Your Batch is Bad?

If at any point you find mold on the surface of your ginger beer while it is brewing, throw the whole batch out, even if it is only a tiny bit of mold. Ginger beer is easy to re-make (especially since you already have your ginger starter ready to go), and it is not worth sacrificing quality and health even if it is frustrating to have a failed batch.

Any Questions??

I hope this post will inspire you to make your own naturally fermented healthy ginger beer at home!

  • 2 cups filtered water

Ginger Beer:

  • 1 cup ginger starter instructions below
  • 1 gallon filtered water or well water
  • 1 1/4 cups organic cane sugar
  • 1/2 cup fresh lemon juice
  • 1/3 cup fresh ginger peeled and grated

Instructions

Prepare the Ginger Starter:

  • Peel and grate a 1-inch nub of fresh ginger (about 1 tablespoon).
  • Add the grated ginger, 1 tablespoon of sugar, and two cups of filtered water or spring water(non-chlorinated) to a jar and stir. Cover the jar with a cheesecloth or towel and secure it with a rubber band. Allow jar to sit in a dark place for 24 hours.
  • Once a day for 4 to 10 days, add one teaspoon of sugar and one teaspoon of grated fresh ginger to the jar and stir well.

  • After 3 to 5 days (longer if your house is very cold), the liquid will begin bubbling when you stir it. Once you can see and hear bubbles without touching the jar, your ginger bug is ready to be used. If after 7 days, your ginger bug is still not bubbling, continue adding a teaspoon of sugar and ginger until it does. Note that amount of time it takes to get a ginger bug active varies widely depending on the temperature of your home and the activity of the bacteria and yeast.
  • Use the liquid from ginger starter to make ginger beer (instructions below).

Make the Ginger Beer:

  • Fill a gallon-sized jug most of the way up with spring or well water (do not use water from the tap unless your house runs on a well). This water should be room temperature or slightly warmer (aim for 70 to 78 degrees).
  • Stir the ginger starter well. Add 1 cup of the ginger starter, sugar, lemon juice, grated ginger, and the ginger starter. Stir very well. Cover the jug with a cheesecloth or towel bound by a rubber band and put it in a dark place at room temperature for 8 to 10 days.

  • Once the ginger beer is ready, give it a taste test. If it doesnโ€™t taste sweet, add additional sugar and ginger – once you bottle the brew, it goes through secondary fermentation and the probiotics will need more sugar to survive.
  • At this point, your options are to either bottle the ginger beer as-is or flavor it prior to bottling it. If you choose to leave the ginger beer as-is, simply transfer the ginger beer toglass bottles, secure the lids, and place bottles in the refrigerator.
  • If you choose to flavor the ginger beer, add your flavoring ingredients to the flip cap bottles (see blog post for flavor ideas and instructions for secondary fermentation) prior to filling the bottles up with ginger beer. Secure the lids on the bottles and leave at room temperature for another 2 days.

Questions and Reviews

  1. Hello Julia, I am trying your version for the first time. I have brewed ginger beer and kombucha off and on for about 3 years. I have typically boiled my ginger and only completed a single fermentation –straight to the bottle. My question is why the two step fermentation –More probiotics? Any way to back this up?

    1. Hi Dale,

      Fermenting the ginger beer a second time allows more probiotics to grow and also creates a deeper flavor. Those who like a sweeter ginger beer have the opportunity to achieve both the sweetness they want through secondary fermentation and also ensure they aren’t missing out on a decent concentration of probiotics. Let me know if you have any other questions! xo

  2. Weโ€™ve just made our first batch and it is delicious! My kids want to drink it but Iโ€™m not sure maybe they need to wait to grow a bit older.

    1. LOL, probably a safe idea ๐Ÿ˜€ There isn’t very much alcohol in it, but you don’t want to risk any issues, that’s for sure ๐Ÿ˜€ xoxo

    1. You could leave it at room temperaure for a few days and see if it springs back to life. If it’s still flat after a few days, I would start again.

  3. Hi! Very excited to try this- my starter is in the pantry and is already starting to bubble! I am wondering if using a plastic gallon jug for the first fermentation will impact the quality of the ginger beer… my roommate goes through milk like crazy and I don’t have glass jars on hand larger than 16oz. Will the plastic give me problems? Is it a better move to use several smaller glass jars? Thanks!

    1. Hi Caraline!

      Yay, exciting!! It’s probably ready to use then! I would recommend using glass for sure. Plastic can interfere with the fermentation process. Hope you love the end result! xoxo

  4. Hi Julia!

    Thinking of doubling the recipe. Do I use two cups of the ginger bug which all of it? Or I should not double it. Would it affect the fermentation process?

    1. Hi Joaquin,

      You can definitely double the recipe by using all of the ginger bug! It won’t affect the fermentation process. Just be sure you use one large jug for the batch, or if you break it between two jugs, make sure the same amount of ginger bug ends up in both jug ๐Ÿ˜€ Let me know if you have any other questions! xo

  5. Hi Julia!

    I am wondering if I can a double the recipe and use all of the ginger bug. I did it the first time and it was a hit and I am trying to do a bigger batch.

    Thank you,

    Joaquin

  6. Hello! I am wondering for getting the brew batch going do I use just the liquid from the ginger bug or just take a one cup scoop from all of it, ie: including the bits of ginger? Thanks!

    1. Hi Tifany,

      Give the starter a good stir before using it to brew a full batch ๐Ÿ™‚ Hope you love it! xo

      1. I wouldn’t. Similar to kombucha or any fizzy drink, ginger beer can explode easily if shaken ๐Ÿ™‚

  7. Thanks SO much for the instructions – I have researched dozens of sites and yours is the ONLY one I can find that doesn’t boil the ginger. I think the ambient-temperature fermentation yields a better probiotic drink since everything ferments at room temperature and without heat. I’ve brewed several batches so far, fermenting naturally without yeast and getting satisfactorily fizzy ginger beer.
    Instead of the secondary ferment in flip-top bottles which have to be burped, I’m doing the current secondary fermentation batch in mason jars with airlocks so I can still observe progress but won’t have to expose it to air as when you burp the flip-top bottles.. Will be interesting to see if it makes a difference. After that, it goes into flip-tops and into the fridge to chill and enjoy : )
    Thanks again and keep the info coming!

    1. Thanks so much for the sweet note and feedback, MaryAnne! Do feel free to keep us updated on your batch! I’m interested to know how it turns out ๐Ÿ˜€ xoxoxo Enjoy!!

  8. Hello there,

    Thank you so much for the very detailed discussion about this process. I have a bug, which took me about 2 weeks to get started (London house in May)., and it was your blog that gave me the confidence to just keep trying with this one (whereas the others I had thrown out too soon.) These days it seems the bug is almost too active, if that’s even a thing. The last batch I made, 2 liters with about 2/3 cup sugar (I wanted to try going light) bubbled up explosively in about 3 days and all the sugar was gone! I put some added sugar in and put it in the fridge to slow it down. I am not sure why this is happening. But my question to you is about your process of keeping the mixture open as a primary ferment before bottling as a second. Many online recipes suggest bottling immediately which is what I had been doing. What is the difference and outcome between leaving it out covered with a towel vs putting it into the bottle to ferment?

    Thanks!

    1. Hi Mernie,

      I leave it covered with a towel to allow the probiotics and yeast air to breath. This helps with their reproductive process, where when you bottle a fermented beverage, the fermentation process slows down. It sounds like slowing down the fermentation would be a benefit in your case, so perhaps bottling it right away is a good move for you! Let me know if you have any other questions! xoxo Happy brewing!

    2. @Julia, i was just wandering something along these lines. As long as we keep the mixture uncovered and stirr it daily we provide oxygen, right? This would mean that the yeast is actually not fermenting but using cell repsiration (in this case the bubbles we see would be oxygen and not CO2) which allows the yeast to multiply much faster. Then in the last step which you call the secondary fermentation we create an anearobic environment which pushes the yeasts from respiration to fermentation. Do you agree???
      Thank you for your recepy and the interesting discussions! Thanks to you I have a ginger bug now and hope I will be able to get some tasty fizzy ginger beer out of it in a couple of days!

  9. Hello, what do you recommend we do with the bug if we do not want to make ginger beer regularly? Can I put it in the fridge and then take it out when i need it again?

    1. Hi Mida!

      I haven’t tried keeping a ginger bug alive without continuously using it to brew, so I can’t be too sure, BUT I think you could keep it in the refrigerator the way you would sourdough starter. This will slow down the activity of the probiotics and yeast substantially, so just note that they will not live forever when refrigerated. My guess is this would work for about 2 weeks before they start to die off. Let me know if you try it and are able to successfully revitalize the starter for a new batch! xoxo

  10. Hello!

    Thank you for such a thorough recipe. I just finished my first successful ginger bug and brew. I didnt have a grater so I finely chopped the ginger which seemed to work. Can I re-use the ginger pulp from the first batch to continue the second batch?

    1. Hi Jennifer,

      Great, I’m glad the chopping worked! I’ve never tried re-using the ginger so I can’t be sure whether or not it would work. If it were me, I would go with fresh ginger just to be sure. Happy brewing! xoxo

  11. Hi! Iโ€™m on week one of the first fermentation and Iโ€™ve yet to see any bubbles form, even when stirred. The yeast is building up on the bottom on top of the grated ginger, though. I added a little more ginger (it wasnโ€™t gingery enough for me) in hopes that it would kick start it some, but itโ€™s still very flat and sweet. I make kombucha as well and know you can let it go up to 2 weeks in the first fermentation. Is this ginger beer the same way? Iโ€™m going on vacation for a week and just want to be sure I wonโ€™t come back to it ruined. Thank you!

    1. Hi Nathan,

      The starter is tricky, for sure. Sometimes they take off almost immediately and sometimes they take a while to activate. It can take anywhere from 2 days to a couple weeks to get the starter going, and even then there is no guarantee that the probiotics will grow enough to culture. The key seems to be the temperature of your home…if it is consistenly between 70 and 80 degrees, the starter will be more likely to work…any cooler than that and it can be hit or miss. It may be worth starting a new ginger bug using different ginger to see how it goes and do a side-by-side comparison. I hope this helps! xoxo

  12. Hello Julie,

    Thanks for your informative blog on not only ginger beer but โ€˜growingโ€™ a ginger bug.

    As a Covid project, started a ginger bug & beer and my first attempt didnโ€™t work too well due to it not getting hot enough.

    However, the 2nd attempt, we tried a ginger with tumeric bug and it really took off well. Upon secondary fermentation, we tried 2 flavours: maple pear ginger tumeric and apple ginger tumeric. Happy to report the maple pear is a great combo!

    Thanks again for the brew recipe and the coconut milk idea. Since our last brew turned out well, we plan to do a cold spin on golden tea next ๐Ÿ™‚

    1. I’m so happy to hear round two worked! That’s so cool you used turmeric too…I will definitely be trying this, myself! Thanks so much for the feedback, and enjoy! Happy brewing ๐Ÿ˜€ xoxoxo

  13. I am on my second attempt of making my ginger bug. The first one I kept in a dark cupboard and it looked good the first 2-3 days with bubbles, but then suddenly it stopped fizzing and making progress. The second one is currently on a seedling warming mat and again looked good for the first 2 days, and now has stopped producing any bubbles or noise. Both times I have never had a white substance on the bottom that I can see, just a bunch of ginger. The ginger also has a penchant for floating to the top and staying there. Do you have any troubleshooting tips?

    1. Hi LJ,

      It is common for bacteria/yeast to be active a few days in and then go dormant after a couple of days and bounce back around 7 days (this happens with sourdough starter pretty frequently). I wouldn’t be concerned about the lack of presence of white substance since the starter is still young. If it were me, I would just keep at it. As an alternative, if you’re feeling bold, use the starter as soon as you see the bubbles…the culture will not be very mature, but it could still work! Let me know if you have any other questions! xo
