1 Gallon Glass Kombucha Jar

The classic 1-gallon kombucha brewing jar — a wide-mouth glass vessel with a breathable cotton cloth cover and securing band, sized for a full batch of kombucha, jun, or water kefir. The cloth lets your brew breathe while keeping fruit flies, dust, and debris out; the thick, BPA-free glass never takes on flavors or scratches the way plastic does. Full 1-gallon batch size — the standard for home kombucha: roughly 12–14 bottles per brew Breathable cotton cover + band included — airflow in, fruit flies out, SCOBY undisturbed True wide mouth — easy to add the SCOBY, check your brew, and clean between batches Thick clear glass — watch fermentation progress without lifting the cover Doubles as a storage jar — between brews it holds grains, beans, or sun tea Ready to level up? Pair it with our airlock fermentation jar for vegetables, or go hands-off with the continuous brew dispenser . Browse the full Fermentation Station for weights, swing-tops, and bottling growlers.
