Tröegs Brewery’s Flagship beer, HopBack Amber Ale derives its name from a vessel in the brewhouse called a hopback. As the ‘wort’ is being transferred from the brewhouse to fermentation it passes through the hopback vessel. Packed full of fresh whole flower hops, the wort slowly circulates through this vessel extracting the essence of the aromatic hops. This vessel adds more time and more hop character that creates a fresh, spicy taste and rich caramel note that defines this signature ale.
