Description

A very dark, full-bodied, roasty, malty ale with a complementary oatmeal flavor. The sweetness, balance, and oatmeal impression can vary considerably. History: A variant of nourishing or invalid stouts of the late 1800s using oatmeal in the grist, similar to the development of sweet stout that used lactose. An original Scottish version used a significant amount of oat malt. Later went through a shady phase where some English brewers would throw a handful of oats into their parti-gyled stouts in order to legally produce a ‘healthy’ Oatmeal Stout for marketing purposes. Most popular in England between the World Wars, was revived in the craft beer era for export, which helped lead to its adoption as a popular modern American craft beer style that uses a noticeable (not symbolic) quantity of oats. Style Comparison: Most are like a cross between an Irish Extra Stout and a Sweet Stout with oatmeal added. Several variations exist, with the sweeter versions more like a Sweet Stout with oatmeal instead of lactose, and the drier versions more like a more nutty, flavorful Irish Extra Stout. Both tend to emphasize the body and mouthfeel.

Examples: Anderson Valley Barney Flats Oatmeal Stout, Broughton Scottish Oatmeal Stout, Figueroa Mountain Stagecoach Stout, St-Ambroise Oatmeal Stout, Samuel Smith Oatmeal Stout, Young's Oatmeal Stout
