The champagne-like bubbles, distinctive hop bouquet, and balanced character of Liberty Ale® revives centuries-old ale brewing traditions that are now more relevant than ever. First introduced in 1975, Liberty Ale® is brewed strictly according to traditional craft brewing methods, and uses only natural ingredients — pale malted barley, fresh whole-cone Cascade hops and a special top-fermenting yeast, and water. The yeast used during fermentation produces many of Liberty Ale's subtle flavors and characteristics. A natural process called "bunging" creates gentle carbonation, and the practice of dry hopping (adding fresh hops to the brew during aging), revived by Anchor, creates its unique aroma. Liberty Ale® was first brewed to celebrate the bicentennial of Paul Revere’s historic ride. As the first modern American IPA brewed after prohibition and the first modern American single-hop ale and dry-hopped ale, Anchor’s Liberty Ale® is the original craft brewed ale and the historic beer that started a revolution.
