Gifts for Kombucha Brewers

The kombucha brewer who has been at it for more than a year isn't looking for a starter kit. They've named their SCOBY, they have opinions about tea sourcing, and they've already worked through two batches of too-sweet first fermentation. These gifts are the tools that experienced brewers reach for when they stop guessing and start measuring — and the accessories that signal someone actually understands what they do.
