How to Make Ginger Beer (Fermentation Recipe)
Making Ginger Beer is awesome and easy – although you require a little patience; its biggest downside is it will take at least 2-4 weeks before it’s ready and demands your attention at the start of the process. The upside is the depth of flavor, natural carbonation that is something magical to have created.

Our recipe is based on the writing of Sandor Kraut though the quantities of ingredients and technique are pretty similar across the Internet as I suspect they have been for hundreds of years.
There are two parts to the process – the initial small fermentation (called the ‘bug’) which gets things really kicking (almost like a starter for sour dough), and then a secondary fermentation with additional ingredients.
Ingredients
- Water
- Ginger (a large piece about 8 inches long)
- 1.5 cups of sugar
- 2 lemons (it just isn’t the same without them)
Instructions
- To start the bug, place 1 cup of room temperature water in a jar or bowl (I use a mason jar). If your tap water is chlorinated, allow it to sit open to the air for an hour before proceeding (this will help eliminate the chlorine and will help the fermenting).
- Add 2 teaspoons of sugar and 2 teaspoons of finely chopped ginger. Stir well.
- Cover loosely with cheesecloth; I use a single layer as natural yeasts will enter the jar but flies will not. I hold it in place by screwing a band around it (just not using the lid).
- Store in a warm, dry place.
- Add ginger and sugar (the same amounts) every day, stirring after. Repeat until your contents become fizzy (you’ll be able to hear it). This should take a couple of days and up to a week. Our apartment has a bit of the initial chill of winter in it so it takes its sweet time.
- Boil 2 liters of water with six inches of chopped ginger root (for a strong flavor, you can use less if you’d like) and 1.5 cups of sugar.
- Allow the mixture to cool completely and strain the contents to remove the solids.
- Add the juice of two lemons, and this syrup to your ginger bug.
- Strain the mixture to remove solids.
- Add water (again a good practice is to let the chlorinated water sit for a bit) to increase the contents to 4 liters (roughly a gallon)
- Bottle in clean bottles – you can get them from brew-your-own beer stores, reuse Grolsch pop-top bottles or use beer bottles if you have a capper. We’ll share how to sterilize/clean later this week (it’s a post unto itself). Avoid regular plastic pop bottles – the pressure of fermentation is intense enough to stretch and eventually explode them.
- Store until the bottle is hard to squeeze (in the case of plastic). It should take 2-3 weeks.
- Refrigerate before opening and know that this can be a little more prone to making a mess when opening so be near a sink, with a glass!
It’s really fantastic…
If you make Ginger Beer, do you do anything differently?

I will finally do it! I love ginger beer!

I add a few sultanas to help the initial fermentation begon but otherwise same.
Do not store in house of it can be avoided as bottles can explode and ruin carpets and walls – yes the voice of experience who stored them in a wine rack in the hallway.
cheers chookie2
The pressure of fermentation is also strong enough to make glass bottles explode (I have 6 stitches to prove it.) It sounded like pipe bomb went off in the kitchen. I recommend plastic or using a cork rather than the beer bottles with porcelain caps. That said, homemade ginger beer is delicious.
I’ve fermented it in 2 ltr soda bottles, squishing the sides of the bottle in about 1/2 inch each side (1/4 inch for 20 oz bottles). It will become firm soon in the summer time, not sure how long the sides will fill out and become firm in the winter, or in the fridge.
Do I strain it again before bottling, after adding the bug? Or do I leave all the bits of ginger that are in the bug?
Hi Melissa, you do indeed want to strain both (you cna do this after combining) – I’ve updated the post to make that clearer – thanks for the question!
Hi Joel, just wanted to say that I made it exactly the same as your recipe and it turned out perfect!! My husband and little girl loved it and I will definitely be making it again
Thanks Joel, the bug is bubbling away and the syrup is almost boiling on the stove
I bottled my ginger beer about 3 weeks ago and have been excitedly awaiting the results, however i just noticed 3 of the 5 bottles have what look like mold blooms floating in them. the other two bottles are fine and are getting fizzy. Could the mold be a sanitization issue? I used 1/2 liter plastic soda bottles cleaned with regular dish soap and then sanitized with Five Star. The moldy bottles are all green, while the ok bottles are clear, but that could just be coincidence… any thoughts? I want to figure it out before i start another batch!
Stephanie, total bummer – sorry to hear.
I haven’t had this before but looked into it at Wildfermentation.com (it’s the Sandor Katz site we share from time to time and I love) and found this:
http://www.wildfermentation.com/forum/viewtopic.php?f=8&t=61
Read the whole thread – but here’s what I gleaned – as it’s a forum you have to take it for what it is – the experience of others not necessarily ‘scientific fact’:
1) It could be sanitization.
2) It could be a yeast film (although it sounds like yours indeed is mould)
3) Mould needs air to grow – it could be a headspace/ too much air in the bottle issue.
4) It could be a vegetation issue – i.e. not strainer enough.
That’s a lot of variables but all 4 sound like good places to check before starting again.
Is any of that helpful?

Just my 2 cents, since I’ve noticed this with mine as well. When I opened the bottles, it all mixed together and tasted just fine. No mold smell and no off flavor. I believe it is a filtering issue. It is just a blob of the ginger and other spices that have collected on the bottom area, much like what happens with Kombucha’s expended yeasts and bacteria that are harmless.
THanks for adding this Trudi!
Thanks, I had looked around on Sandor’s site but missed that particular post. I’m not sure what I actually have is mold since it’s floating in the liquid, not on the surface. Although I suppose it could have started on top and submerged as it grew (they’re about .5 to .75″ in diameter, tan colored and fuzzy looking). all my bottles had the same amount of headspace, and there’s definitely sediment, but it just looks like the little white yeasties.
I guess i’ll wait and see how it turns out after it carbonates enough. I assume I will know by the taste if something is really bad. thanks for the suggestions!
The other possability is that air is seeping into the boddle (i.e. the lids didn’t seal) which could feed the mold. I’ve never enountered it so can’t reccomend consuming it but do reccomend doing research to see the experience of others (specifically those who would be recognized as experts or experienced with it). It may be worth posting a question in Sandor’s forum (the link in this thread) to see if anyone there has ecperienced the same; but quality of answer will be reliant on who answers it.
I just have bottled the ginger beer. I took the liberty of burning the sugar a little bit to give it an amber brownish color that i personally like.
However, is there any way i could have screw it up and end up killing or poisoning my friends?
I’m really concerned about this particular topic.
Cheers.
Feedmejunk,
I unfortunately can’t make that decision for you – but I do drink it. If you google WILD FERMENTATION FORUM you’ll see a tonne of posts all claiming that you can’t hurt a fly with it. My learning is based on reading, research and experimentation and if you poured me a glass I would drink it but can’t reccomend that you do. This article explains why I can’t reccomend in greater detail; I know it’s not what you are looking for but it explains why…

Joel, a little bit of an update:
Today was the second week of storing and i gave it a try. I left it in the fridge all night and i opened carefully, it had A LOT of gas! i had to open it and close it a few time for the liquid not to be spilled…
Apart from that, there were sediments in the bottom, but i didn’t mind.
It tasted delicios, fresh lemony, a little mit acidic and with a strong and sweet ginger aftertaste.
I have never had actuall ginger beer because in my countr (Argentina) doesn’t exist, so i’m really happy with the final product, but i don’t have a clue if it tastes any similar to ginger beer.
I drank almost 2 litters so far an i’m a little tipsy, so thank you for the recipie!
So I am trying again. I started the bug a week ago, after 4 days it got very fizzy, but i wasn’t prepared to bottle that day. Now, two days later there is no fizz at all though i’ve been feeding it every day. Did I miss the window? will the yeasties perk up again, or should I just start over?
Stephanie,
Sorry to hear. I’d start anew but keep your current one going to see if it turns. Mine doesn’t fizz wildly although if I give it a gently jostle I can see some bubbles.
The most common reasons for no fermentation include not feeding (but you are), chlorinated water, soap residue in the jar or too much/ too little heat.
Let us know what happens and what you try!
Joel
I started a new bug while continuing to feed the one that had stopped bubbling. After a couple of days the old one just started getting moldy. But the new bug is fizzing away happily now, and I will be bottling tonight! We’ll let you know how it turns out!
