Dark roasted malts, such as black patent malt (the darkest roast), can lend a bitter coffee flavor to dark beer. Some brewers like to further emphasize the coffee flavor and add ground coffee. The ABV of these coffee-flavored stouts will vary from under 4% to over 8%. Most examples will be dry and bitter, though others add milk sugar to create a sweet stout which may then be given a name such as Coffee & Cream Stout or just Coffee Cream Stout. Other flavors such as mint or chocolate may also be added in various combinations.
Another great collaboration of beer and coffee
