Hi all! I know this is very similar to a question i asked previously but I have a repeat issue! I brewed the summer ale recipe late on thursday night, pitched the yeast at 5am on fri morn. I got a decent enough frothy top in the FV and good bubbling action in the airlock by fri night. The bubbling has now stopped, totally! there is a lot of yeast built up at the bottom of the FV, i can see it through the side of the bucket. I havent opened the lid so think it should still be airtight. Is it really worth doing a gravity check after only three days?
