Irish Ale is a traditional beer style that originates from Ireland. It is typically characterized by its smooth, malty flavor and moderate alcohol content, usually ranging from 4% to 6%. The use of roasted barley gives it a rich, dark color and a slightly sweet taste, often with hints of caramel and toffee. This ale is often served in a pint glass and is known for its creamy head, which is achieved through a nitrogen gas infusion. Popular brands include Guinness and Smithwick's, both of which showcase the unique qualities of Irish brewing traditions.
