Barleywine Malt Experiment

To help learn the differences between base malts, brewers all made the same English-style barleywine but each showcased a different base malt.

Effect of O2 on Fermentation

Two batches of beer, one hoppy West Coast-style red ale fermented with Chico ale yeast (Fermentis S05) and one Belgian single fermented with Chouffe (WLP550), were brewed to determine the effects of O2 on fermentation. Each batch was 10 gallons, and the wort was split across two carboys in each case. For each 10 gallon batch, one of the two carboys received O2 prior to pitching the yeast, while the other control batch received no oxygen. In both cases the two carboys were fermented in the same environment, and had the same pitch rate. The brewers noted that the batches showed no difference in lag time/final gravity.

Attendees of the July 2014 meeting blindly tasted the finished beers and voted on which of the two beers in each case got oxygen. The result was that the hop driven amber had a near 50/50 split on votes, but that tasters were overwhelmingly able to correctly identify which of the two Belgian beers received oxygen. Many tasters cited the
oxygenated beer’s less phenolic flavor and aroma profile as their reason for selecting it. It was noted that the oxygenated Belgian single did eventually end up with as much character a few weeks later.
