So I made an IPA this past Sunday that has a higher starting gravity than I'm used to (1.076) and I'm not sure if fermentation is working or not. It's in a bucket that seems to be sealed well with a blow off tube. I'm not getting bubbling from the blow off tube and it's been 40 hours. If i move the hose it will blow bubbles. The lid on the bucket is bowing up slightly like it usually does and if i push down on it the blow off tube bubbles. Am I just paranoid and use to seeing a lot of activity or may there be an issue with my fermentation. Any advice is greatly appreciated. Cheers.
