Round 2 - ESB vs. American 2

Entering the second round after only 10 days of first round action. And some action it was. Both strains gave a great performance, and showed off their distinctive personalities. London ESB gave off larger bubbles, and though the krausen foam was just as large, it didn't seem to exhale as many air-locked bubbles. It also tried to finish earlier, so it got a couple spins to loosen its clumpy yeast cake. In the end it really settled out good and clear.

The American 2 strain performed with much more vigor. Wildly swirling around, it looked like it was boiling in carboy. Finer sized bubbles succumbed to strong currants on there way to the foamy surface. Simply amazing! Exhalations slowed but never really seemed to stop. Also, a 2 inch thick and creamy foam head never wanted to settle back into the beer, and it remained pretty cloudy at ten days.

Each batch was packaged into ten 12oz. bottles (with Cooper drops) and the rest kegged (3gal each). Please look back to Round 1 for their ending stats.

Round 2 already showed signs of fermentation within 1 hour on their yeast cakes. After five hours they were both fermenting wildly with considerable krausen foam. Eventually the ESB started to settle down, while the American 2 built up even more milky/top-cropping yeast, and decided to blow out of the airlock late the next day. It continued to blow off slowly through the night. photo coming soon

This round is very similar with malts and color. The gravity is a couple points higher, and it was mashed similarly to the first round. The hops however, were increase at both bittering and aroma with one additional ounce. The separation of additions was also increased, with only two aroma addition at 15min & knock out. The hop presence is definitely more pronounced with the ESB getting Phoenix/Saaz and American 2 getting Glacier/Saaz blends. The Saaz has a soft aroma with only 2.3 alpha acids which should provide a good balancing effect with the stronger English aroma hops.

Great recap :-) Any indications of taste differences? I noticed you're going on to round 3 and then the finals, so maybe I'm a little premature in asking.

Adam, no...not yet. You are just gonna have to wait a bit longer.
