How much does it cost to make Kombucha Bottle (12 oz)?
About $1.04 per 12 oz bottle, 29.7% of a $3.50 price: 39 cents of brew (tea, sugar, fruit, and starter) and 65 cents of bottle, cap, and label. If you refill your own swing-top bottles, it is 39 cents; if you buy glass by the case, about $1.47.

Ingredients and packaging (the Bottle + cap + label line). Labor, fuel, and stall or platform fees come out of these figures.
Organic tea and cane sugar come to 12 cents a bottle. The fruit juice or puree added for the second ferment is 25 cents, and starter saved from the last batch adds about 2 cents, because the culture regrows. That is 39 cents of brew against 65 cents of packaging: the amber glass, the crown cap, and the label are 62.5% of the $1.04. The brew is already cheap; the bottle is the number you can change.
The 65 cents assumes volume pricing. A small brewer buying by the case pays more: MoreBeer sold a case of 24 amber 12 oz longnecks for $17.99 in October 2026, 75 cents a bottle, or 64 cents at eight cases or more. Oxygen-absorbing crown caps run about 6 cents each in a 144-count bag, and a first run of 1,000 printed roll labels can cost 38 cents a label. At the eight-case price that is $1.08 of packaging and $1.47 a bottle, 42.0% of $3.50. By the pallet the glass drops to about 36 cents (Berlin Packaging listed 4,050 longnecks for $1,439.17), but that means storing enough bottles for 84 batches of 48. The other way out is to skip the bottle: kombucha sold from a keg in a cafe, or poured into a customer's own growler at a market, costs only the 39 cents of brew per 12 oz.
The cost the recipe leaves out is keeping it cold. Raw kombucha keeps fermenting after it is bottled, and warm storage raises the alcohol. In one British Columbia Institute of Technology study, two of three brands kept at room temperature for three weeks went over 1% alcohol, while the refrigerated bottles did not rise. Under the rules of the federal Alcohol and Tobacco Tax and Trade Bureau (TTB), kombucha that reaches 0.5% alcohol by volume at any point, including in the bottle after it leaves the brewery, is an alcoholic beverage: it has to be made on TTB-qualified premises and taxed and labeled as alcohol. So a raw bottle has to stay refrigerated from bottling until it is drunk, and every warm hour in a van or a market stall counts. The cold room, the cooler, and the alcohol tests are not in the $1.04, but every bottle sold pays for them.
