My first batch of kombucha hit 14 days and tasted like sour vinegar

I followed the starter kit instructions to the letter and left it fermenting for the full two weeks in my pantry. Around day 10 I got curious and tasted it, and it was already getting that tangy flavor. By day 14 it was undrinkable, like straight up vinegar with a weird floaty thing on top. Has anyone else had a batch go way too sour because they left it too long, or is my kitchen just too warm?

Cut that ferment time down to 10 days max, your kitchen is too warm for the full two weeks. That floaty thing is just a yeast blob, totally normal, but the vinegar taste means it went too far. Next batch, taste it every day after day 7 and bottle it when it hits that sweet spot for you.

Read an article from one of those fermentation blogs that said temperature swings mess with things more than people realize. If your kitchen stays above 75F, that two week window shrinks fast and the vinegar taste pops up sooner. They recommended keeping a little log of temps and tasting notes for each batch so you can spot the pattern. Might help you dial in your own timing.
