As I was brewing my latest batch, I heard my hydrometer, which was drying on the counter, fall to the ground. I wasn't able to get a replacement until two days into fermentation, there's already fun coming out of the blowoff tube (as graphic as that sounds). Is it even worth getting a gravity reading? It's certainly not OG, it's like T-Minus 2 days OG. Would it still give me any reasonable indication of fermentation completeness? I'm brewing an APA, so fermentation times shouldn't be horrendously long, as I've already got a fair amount of activity after a day or two, but I know that activity doesn't equal fermentation.
Any tips?
