Gluten Free beer. The dubbel style originated in Belgium, possibly as a "second style" offered for sale by monastic breweries. Green's Endeavour Dubbel is the world's first version of this style made with no barley. In the classic dubbel fashion, a hint of dark-sugar and toffee flavor; and a traditional Belgian yeast bouquet. Makes a fine aperitif; also great with traditional Italian antipasto, soft cheeses, gluten-free baked goods and Belgian-style "pomme frites."
