Bullion Hops is a sibling to Brewers Gold and was a seed collected off a female plant taken from a wild variety from Morden, Manitoba. It was open pollination that gave rise to this abundantly bitter hops variety that sprung in the year 1919. Bullion hops has been dubbed the first super alpha hops and deservedly so, as it has a skyrocketing 8%-12.9% alpha acid rating.
Bullion Hops, as you would guess, is a wonderful bittering hops. Bullion has a strong zesty aroma. It is commonly used in darker beers including Stouts, Porter, and Scotch ales, but is also used in Bitters, and IPA's. Buillion produces dark yellow lupulin oil, and has a moderate yield. It's production has been on the decline for decades, as the new super alpha varieties have taken its place over time. So, it may be a little difficult to find for your homebrews and commercial beers.
