Roast barley are unmalted barley kernels which have been toasted in an oven until almost black. Roast barley is, after base malt, usually the most-used grain in stout beers, contributing the majority of the flavor and the characteristic dark-brown color; undertones of chocolate and coffee are common.
Essential for stouts, it imparts a distinct, roasted flavor to Stouts. Other dark beers also benefit from smaller quantities (2 – 6%). Small amounts are OK in Porters, provided it doesn’t overpower the chocolate/caramel notes.
