Fermentation Cogitation

(Editor's Note: This post originally appeared on http://sites.google.com/site/billsbrewing on June 21, 2010)

The two beers which I have fermenting right now are the Light and the Dark. Each of these was brewed with the same yeast strain, White Labs American Ale Yeast WPL060. They are being stored in the same location, and so have been kept at the same temperature. However,the Light has seemed much more aggressive in its fermentation. I had to switch out my standard three-piece air lock for my makeshift vinyl-tubing-submerged-in-a-bucket-of-water air lock.
