The how and why of kombucha, a fermented tea beverage.

I love kombucha.

Several years ago, I became interested in it, but rarely bought it, as it’s in that category of pricey, cool products that are too expensive for this Dutch guy to buy. I mentioned, off-handedly, to my wife once that I wanted to try and make some myself, but never really did anything until Christmas of 2015. That year, we decided to challenge ourselves into trying to find heartfelt gifts for each other with a $10 price limit. I bought her some earthy cosmetics and loose-leaf tea, and she bought me the supplies to start making my own kombucha.

I was hooked. The process was easy enough, the product was delicious, and the cost was a fraction of the store-bought product. Since then, I’ve been making it constantly, and have produced (and drank the majority of) a few hundred litres of it.

At this point, I feel it necessary to explain why I drink kombucha. In most kombucha-related circles I’m in, it seems that the primary reason is the purported health benefits. I’m not in it for that. I could not care less about fancy health stuff. Sure, it may have some benefits—I do have some things I’ve noticed that some might attribute to the drink—but the fact that I’ve seen at least 50 health reasons to drink it makes it feel a bit like “snake oil”.

Why I drink it:

Now, if you’re sitting there thinking, “I want to get on this bandwagon!” here’s your first step: gather the supplies. Most people recommended doing a one-gallon batch, and not going much smaller than that. (The smaller the batch, the more finicky the ratios of ingredients can be.)

What you’ll need to get started:

Have all your supplies ready? Let’s head over to step two: basic brewing. The basic process of making kombucha is very simple! Once you’ve got your supplies laid out, let’s start.

The Brew Cycle

  1. Boil half of your three litres of water. Once boiling, add the tea and steep for about 5 minutes.
  1. Remove the tea and dissolve the sugar.
  1. Add the remainder of the water. Before continuing to step four, you’ll want to make sure your sweet tea is at room temperature, as high temperatures can kill the fermentation cultures.
  1. Combine the sweet tea and starter fluid in your jar, then add your “starter fluid”.
  1. Cover with a cotton cloth (not cheesecloth as it’s too loose) and let it sit for 7-10 days, at room temperature and out of the sunlight. In general, it’ll go faster the warmer your home is, so if your house is cool, find a warmer spot. In winter months, I’ve brewed mine on top of my fridge, where it benefits from being higher, and also from the warmth generated by the fridge.
  1. After about six days, stick a straw down past the newly forming pellicle, place your finger on top, and pull up a sample of the fluid. Do this each day until it has a combination of tartness and sweetness that you like, then move on to step 7.
  1. Bottling day! Set aside two cups of the kombucha (the “starter fluid”) and, if you want, your SCOBY/pellicle, for the next batch, then divide among your bottles. This is when you’d add flavouring items, detailed below. If you’re not adding any flavouring elements, and you want strong carbonation, you could add a quarter teaspoon of sugar to fuel extra carbon dioxide production. You’ll also start your next batch at this point, though you can wait a few days as well. (Your “starter fluid” will continue to ferment.)
  1. Seal your bottles and keep them at room temperature for about 48-60 hours. This is called the second fermentation. If you’re using plastic, you’ll be able to feel them get hard as the carbon dioxide, one of the products of fermentation, builds up. Keeping the bottle sealed will trap that carbon dioxide, which will give you fizz when you finaly open it.
  1. After 48 hours, it’s ready to drink, or place in the fridge to slow the pressure build-up.

Second Fermentation Flavouring

When you bottle your kombucha for the second stage of fermentation, you can add a myriad of fruits, vegetables, and herb combinations to add to the flavour of the drink. The basic idea is, when you bottle, add some fresh or frozen fruit, fruit puree, pure fruit juice, or any combination, and see what happens. A basic rule of thumb is to use about 1/8 to 1/4 of a cup per 1-litre bottle.

Be careful when you open them for the first time! Just like adding sugar during the second fermentation, the sugars in your flavouring additives can cause some crazy over-carbonation if you’re not careful.

Here’s some of my favourite things I’ve used as flavouring:

Experiment! There’s not much that can go wrong, other than you making a mess in the kitchen or making a strange flavour, like garlic and lemon. Have fun!
