When used properly, in the right beer, nothing can replace black malt for what it lends to a beer. Black malt primarily gives a highly roasted flavor, that carries some bitterness and acidity. But it can also show a deep fruity character reminiscent of currants, blackberries or sultanas. It gives deep contrast to a round malty beer by giving it some elbows, without being pushy. Most importantly, even in very small quantities, it provides a drying quality that brightens up the finish of any beer.
