American Pale Ale. The pale American Glutenberg is a gluten-free ale, brewed from millet, buckwheat, corn and quinoa. Its expressive nose offers aromas of apricot and grapefruit. The palate, of great amplitude, explodes with notes of citrus, especially grapefruit, a true signature of American hops. It presents a raised bitterness, characteristic of this style of beer. Formerly known as American Project.
