Q: How hot is too hot for a kombucha culture?

A: A culture can hit 95-100 degrees for a short time and survive just fine (like during shipping). Optimally, you want to be able to keep it consistently in the mid 70's, or upper 70's at the most. If the temperature goes above 88 for more than a few hours, the bacteria get out of control and throw off the brew. That is why our temperature gauge stops reading above 88 - because the temperature really shouldn't ever be any higher than that.
