I've heard all of the comments about confusing airlocks for hydrometers so there's no need to repeat it. I for one am not fond of opening my fermenting vessel unless I'm fairly certain that fermentation is complete. Then I'll take a hydrometer reading.
That said, I had an IPA with OG 1.060. I let it sit in primary for 2 weeks. It stopped bubbling completely after 7 or 8 but it still sat on the yeast for 2 weeks. Then I racked to secondary with dry hops in a hop bag. I wasn't paying attention to it for several days after racking but now that it's nearing the time I was expecting to keg it, I've noticed that the airlock is bubbling once every 30-45 seconds. There is a pretty good amount of yeast that has dropped out of suspension at the bottom of the carboy. It's been almost a week in the secondary. The bubbles in the airlock indicate active fermentation though right? Regardless of hydrometer reading, the bubbles show that CO2 is being produced and fermentation is definitely active right?
