Golden ale aged in oak with fresh lime peel, lemongrass, and lactose
Key Lime Tau (2π) was brewed in collaboration with Hawkshead Brewery (UK) as part of the Trans-Atlantic Rainbow Project, a series that challenges brewers to come together and brew a beer inspired by a color. In its third year, the 2015 project involved seven UK breweries, each paired with a different American brewery and randomly assigned a color.
Key Lime Tau (4.5% ABV), brewed to embody the color green, is a Mixed Culture Fermentation Ale aged in Oak with Lactose, Fresh Lime Peel and Fresh Lemongrass.
