Ultimate Petroleum is our dense amber brewed with fluffy crystal malt, bright flaked rye, vibrant chili-lime, and real hibiscus flowers. Fermented with our sourdough culture on effervescent beets. Hopped into hellish oblivion with azacca and creamy organoleptic eureka. Notes of oopy-goopy lime leaf, foraged berry jam, comforting marshmallow sundae, pungent fresh pineapple upside down cake, and wet river rocks.
