Brewing your own kombucha at home is one of the most satisfying fermentation projects you can take on, and this stripped-back recipe keeps things beautifully simple. Many commercial kombuchas lean heavily on ginger as a flavoring, which can make finding a safe option genuinely tricky for anyone who needs to avoid it — this recipe skips it entirely and lets the fermented black tea shine on its own. The process is straightforward: brew a strong, sweet tea, cool it down carefully, introduce your SCOBY and starter liquid, and then let time do the work. That cooling step matters more than it might seem, since a too-warm brew can stress the culture and throw off the whole batch. After seven to ten days of quiet fermentation, you end up with a pleasantly tart, lightly fizzy drink that tastes clean and complex without any added flavors to worry about. Tasting daily from day seven lets you dial in exactly the level of tartness you like, whether you prefer something mild and slightly sweet or a deeper, more vinegary finish. Once you have a finished batch, you also have your starter liquid ready to go, so the whole cycle just keeps rolling.

Bring 1 quart of the filtered water to a boil in a large pot. Remove from heat, add the tea bags (or loose-leaf tea in a strainer), and steep for 5–7 minutes, until the tea is deep amber and strongly brewed. Remove and discard the tea bags or strainer.
Add the sugar to the hot tea and stir with a long-handled spoon until fully dissolved, about 1 minute.
