New project in the house – what’s with the bail top bottles? I’ve taken my first plunge into the world of home brewing, or should I say “home fermenting”? I’ve been aware of the health benefits of probiotics for some time, and have occasionally indulged in one of those pricey bottles of kombucha from the natural foods section of the store, but just hadn’t taken the time to try making my own at home.
Serendipity smiled upon me, and I found out that another homeschool mom in my natural foods co-op had been brewing her own kombucha for some time and was happy to share a scoby (Symbiotic Colony of Bacteria and Yeast) with me. I re-read the info I had on kombucha from Wild Fermentation and Nourishing Traditions, paid my friend a quick visit, and brought home two new scobys safely packaged in a covered pyrex container. I shared my extra scoby with another natural foods friend. (They say you should always keep a spare in case something goes wrong with yours, but I knew I could get a replacement from the first friend.) And then – my scoby sat in the fridge. (Which, BTW, is not the best thing for a scoby. Store them at room temperature with enough liquid to cover. A large mason jar works quite well.)
I was excited about the concept, but the original brew I smelled reminded me of a combination of old socks and vinegar, which made me a little nervous. I had a heck of a time tracking down an appropriate container to brew in – very few things come packaged in glass anymore, and I really didn’t need a gallon of olives. Finally, I found some nice gallon containers at Walmart. They had a lid that I didn’t need, but the ridge around the top was handy for holding the rubber band in place that kept the cloth covering the brew in place.
No more excuses – old sock smell or not, it was time to take the plunge. I used the recipe from Wild Fermentation, shown below. I make three quarts at once and ferment them in a gallon container.
Timeframe: About 7-10 days
Ingredients (for 1 quart/1liter):
1 quart/1liter water
1/4 cup/60 milliliters sugar
1 tablespoon/15 milliliters loose black tea or 2 teabags
1/2 cup/125 milliliters mature acidic kombucha
Kombucha mother (SCOBY)
- Mix water and sugar and bring to a boil in a small cooking pot.
- Turn off the heat; add tea, cover, and steep about 15 minutes.
- Strain the tea into a glass container. It’s best to use something wide; kombucha needs adequate surface area and works best if the diameter of the container is greater than the depth of the liquid. Allow the tea to cool to body temperature.
- Add the mature acidic kombucha. when you obtain a culture, it will be stored in this liquid. Save a portion of the subsequent batches for this purpose.
- Place the kombucha mother in the liquid, with the firm opaque side up.
- Cover with a cloth and store in a warm spot, ideally 75- to 85F (21 to 29 C).
- After a few days to 1 week, depending on the temperature, you will notice a skin forming on the surface of the kombucha. Taste the liquid. It will probably still be sweet. The longer it sits, the more acidic it will become.
- Once it reaches the acidity you like, start a new batch and store you mature kombucha in the refrigerator. you now have two mothers, the original one you started with, and the new one. use either the new or the old mother in your new batch, and pass the other one on to a friend (or the compost). Each generation will give birth to a new mother, and the old mother will thicken.
I followed the instructions, and low and behold a week and half later I was staring at this.
Floaty thing – check. Acidic – check. Drinkable – check. Tart, with a slight vinegar taste, but no old socks. Still, I like the fancy flavored brews in the store, so I decided to experiment a bit.
I fished out the scoby.
This thing really does look a little gross, like a rubbery piece of old, mysteriously white meat, of maybe blubber. The blob in the bowl is the original, the new growth is in my hand – fat and healthy.
Straining chunks – I wasn’t ready to face those yet.
Into the bottles.
I flavor the kombucha after the initial brewing, when I remove the scoby and put the kombucha into bottles. You can also used flavored teas from brewing, although those that contain essential oils (like Earl Grey) are not recommended. With this batch I tried 1/4 cup apple cider per bottle in two bottles, one with some blueberries, and one with some raspberries. I didn’t measure the berries, I simply loaded them in until they covered the bottom of the bottle.
I left one of the cider bottles on the counter for three days, the other I put in the fridge. Leaving it out produces more bubbles, refrigeration gives a sweeter brew. All the bottles produced a very tasty brew which I enjoyed very much, so much, in fact, that I got another container and now have two batches going at once. I like to let the second brew age for at least a few days to blend the flavors. IMHO it only improves with age, but I haven’t had any last for over two weeks. I drink it too fast.
In addition to the above flavors, I’ve also tried straight blueberry juice, grape juice, honey and ginger (about a tablespoon of each per bottle), and Ghirardelli Double Chocolate Hot Cocoa mix….mmmm…chocolate. So far I think my favorite is the blueberries, but all are tasty. It’s fun to munch on the bubbling fruit at the bottom of the bottle. The chocolate was a hoot. I got a little nervous because the powder formed an obstruction at the top of the bottle and didn’t appear to blend in well. When I finally popped it open (after almost a two week ferment), the carbonation had built up so much (because of the high sugar content) that it blew the foamy chocolate snake right out of the top of the bottle. So much for the bottle getting blocked – no problem. Most of the sugar was gone by this point, so the flavor was more like straight, strangely effervescent unsweetened cocoa, but it was still pleasant, and highly entertaining. I think the ginger could use more ginger, but I’m not sure how much. Suggestions are welcome, along with suggestions for other flavors. I’ve got some more fruit juice (pomegranate and mango – the Knuten’s pure juice was on sale recently) I’m planning to try, and will probably through some cherries in a batch at some point because we have so many in the freezer. I’m also thinking about getting some water kefir grains to make kefir soda, as the boys aren’t fans of the kombucha. Once I get the last of the beets in from the garden, I’ll try some beet kvass, too.
So why the heck am I bothering with all of this? Sure it tastes good, but it’s also good for you. From Kombucha Cultures:
The intestinal microflora is carefully balanced. The human gut is home to around 400 different species of good and bad bugs. However, the good bugs have to share their environment with bad bugs such as Salmonella, E.Coli and Clostridium. The way to balance between good and bad bacteria is to maintain good digestive health, creating stable “microflora”. It is generally recommended that probiotics are taken on a daily basis to create this balance.Prescription medicines, stress, sickness and especially antibiotics can all disrupt the bacterial balance because as well as killing off the bad bacteria they allso kill off the good bacteria. So you need to restore balance. Probiotics need to be taken regularly to maintain levels of good bacteria. Lactobacillus or lactic acid bacteria is a faciltative bacteria, named as such because most of its members convert lactose and other simple sugars to lactic acid. They are present in the gastrointestinal tract and the vagina. The production of lactic acid makes their environment acidic which inhibits the growth of some harmful bacteria. Large populations lactic acid-producing bacteria regulate the levels of friendly bacteria and reduce the levels of toxic pathogens which cause ill health. Resulting in Kombucha being one of the best skin treatments for acne and an arthritis health drink.Even though the beverage is acidic, it does not cause any acidic condition in the stomach; it facilitates and noticeably promotes the digestion. The “yeasts” found in the Kombucha are of a beneficial kind. Organic Kombucha Tea is considered by some as a delicious ‘Cancer Foods’ or as a natural alternative ‘herbal nutrition supplement’.By altering the pH of the large intestine to a slightly more acidic level, putrefactive bacteria (those bad for your health and causing foul wind production) tend to be inhibited or destroyed. There is no kombucha danger, It will cause no harm to have even ingested Kombucha mushroom. The pH is altered by active good bacteria producing high levels of lactic acid. The presence of this and other acids inhibit the growth of undesirable bacteria, molds, mold spores and yeast, particularly the Candida form.
