Round 1 - ESB vs. American 2

This is the first round of a number of split brew sessions. London ESB is going head-to-head with American Ale 2 to win my preference as a good pale ale yeast strain. It will be a lot of fun finding out how they perform over a few rounds. Read about the break down of this experiment here.

For the first round, the beer style and hopping is a session-like English style bitter/amber. It may be a little light on the bittering hops, but should allow the yeast's fermentation characteristics to be more noticeable. The next rounds will either be higher OG's and/or higher IBU's. Below there is a list of grains for the main mash, then separate listings of hop schedules, followed by brewday stats. Check back in about 1-1.5 months for the final results, or there may be a special post highlighting the results of all these brews.

A couple challenges added almost 2 hours to the day. The lid was on tight during the first sparge. This caused a strange vacuum, that compacted the grains and stopped the flow. We added about a gallon of the second sparge water to mix the grains, vorlaufed, and we were on track again. Then, while adding the first hop addition to the 2nd batch...American 2 ale, Matt mistakenly added the 2nd addition at the beginning. So I made an adjustment, and added only half the original 1/2 ounce of Pheonix bittering hops. Other than that, it was a good brew day, and the OG's were just a couple points above target.

Ted...Can't wait to find out how they come out. I'm thinking I might steal/borrow your idea and do a session like this myself.

Thanks jason,

Go for it. Running a split batch is really a great way to go. Get more experiments in one brewday. Explore yeast strains, or hopping rates, or what ever.

These beers should be interesting. As they have fermented, I've noticed they may be a bit too light with bittering hops, so make sure to add enough. I may have needed to add another 1/3-1/2 to the amount in the recipe. The next round will be different.

What a great way to control the variables. I am really interested to see how it turns out. Thanks!
