Just as it says on the tin! This style dates back to the mid-to-late 1800s, with the discovery that adding oats made the beer just that bit healthier! It lost popularity for quite a while until the 1980s where the style was revived. Oatmeal stouts vary from other stouts due to the oats (of course!) and sweetness. Think roasted chocolatey notes and silky smoothness. A great winter warmer!
