After bottles and waiting 3 weeks, I have openned bottles of my first 2 batches and noticed that the beer has bubbles consistantly rising from the bottom of the glass for at least a few minutes. It is almost like champagne. I rarely if ever had a beer like this. Last night, I looked closely at the points where bubbles were rising from (on the side of the glass was one). It looked as if there was some sediment stuck to the glass. I thinking maybe all it is poor pouring on my part resulting in priming sugar in my glass.
