For the serious home brewer. Our large organically grown kombucha SCOBY is a hefty, powerful culture that will comfortably brew up to 3L per batch — perfect if you get through a lot of kombucha or want to brew for the whole family.
Approx. 16cm in diameter and at least 1.5cm thick, this is our most substantial single SCOBY and arrives plump, active, and packed in its own starter tea so you’re ready to brew straight away. Like all our SCOBYs, it grows a new baby with every single brew — so it really is a lifetime’s supply.
As with all living cultures, size, shape and appearance will vary slightly — that’s nature doing its thing.
