Hop Study - E.K. Goldings

Brewed 2/20/14
Bottled 3/18/14

This is part of a Wort Hogs experiment. The idea coming from the May/June 2013 edition of Zymurgy. We use the same grain bill, the same yeast, and only one variety of hops for each batch.

The hops are used for flavor, bittering and aroma to see how they behave in each role. In theory, this will allow us to better understand how each style of hops contributes to any beer.
