| Other Information |
With Brewer's Gold, Bullion is one of the earliest high
alpha hops in the world. Now largely superseded by bitter types with less
characteristic aromas. Less than 100 acres now grown in the U.S.. There are
many recipes using this hop found in older brewing publications. As a
result, get many requests to use this hop. Many brewers believe this hop no
longer is grown, but this is not the case. |
