Boulevard’s signature beer was a happy accident. Almost 20 years ago, the westside brewery was working on a saison with the funky wild yeast strain Brettanomyces. The base beer sat in tank seven — as in, the brewhouse tank numbered seven — waiting to be blended. When the Brettanomyces didn’t progress as planned, the brewers took to sampling it. As it turned out, everyone who tried that base beer fell in love with the fruity aromatics, grapefruit hop notes and layered spice.
