Continuous-Brew Kombucha Jar with Stainless Spigot
A continuous-brew jar is the setup most kombucha brewers settle on. A wide-mouth glass jar with a stainless (not plastic) spigot lets you tap finished kombucha and refill without lifting the SCOBY, the glass is non-reactive against the acidic brew, and the wide mouth makes it easy to reach in and clean. Brewers like that a spigot jar turns kombucha into a low-effort, always-on supply.
