Mike brewed an Extra Special Bitter (ESB) and an Oatmeal Stout. He split each batch in two and fermented with two different yeast strains. One half of each beer was fermented with White Labs’ WLP002 strain and the other half was fermented with White Labs’ WLP007 strain.

Here is our video post with the results of an English yeast strain experiment.

The experiment was conducted to find out if there was a noticeable difference between the finished beers that used two different English yeast strains and if the differences that we perceived matched up with the written, documented differences that we have read and understood.

Watch this video to see the side by side tastings and evaluations. Is there a difference? Is this difference what we expected?

I think there are more experiments like this one that we could be conducting. Yeast is only one facet in beer to test. Of course, malts and hops are other ingredients we could test and taste side by side to understand the similarities and differences between the two.

Beyond ingredients, techniques like fermentation temperature and mash temperature are other things we can test and discuss the findings, but let’s start with the big items first.

We hope you have enjoyed our Wednesday video series so far. Let us know if there is anything you would like us to vlog about.
