I have 5-6 bottles in rotation and it keeps a pretty constant output. Every 5 days I add one and harvest one. Would be a lot of work and maybe not worth the effort, but mine are making wine.
I've been very tempted to try it. But then I wonder, what would I do with all that wine? I rarely drink.
A nice dry white for cooking would be a bonus though. Dangit, now I'm tempted again.
