Brew the buch,
ditch the $4 bottle.
A gallon of kombucha costs about what one store bottle does. See how fast a brewing kit pays for itself against your bottled-buch habit.
What you buy out now — the spending we compare against.
1 Your kombucha habit
How many bottles do you buy? Toggle per day or per week; tap Edit prices to match the store.
2 Fine-tune upkeep
Fermenting costs very little to keep going. Edit any of these to what you pay.
Counted against your at-home cost for the whole projection.
The gear and ingredients you'd use to make it yourself.
3 Choose your tea
Tea feeds the ferment. It costs pennies per bottle — pick a type or enter your own batch cost and how many bottles it fills.
4 Choose your sugar
The ferment eats sugar, not you — most is gone by bottling. Pick a type or enter your own batch cost and how many bottles it fills.
5 Second-ferment flavor
Fruit or juice in a second ferment adds fizz and flavor. Only your flavored bottles use it.
6 Pick your brew kit
From a single jar to a continuous-brew crock — this sets the upfront cost.
