>>129779>Oatmeal stout is a stout with a proportion of oats, normally a maximum of 30%, added during the brewing process. Even though a larger proportion of oats in beer can lead to a bitter or astringent taste,[21] during the medieval period in Europe, oats were a common ingredient in ale,[22] and proportions up to 35% were standard. Despite some areas of Europe, such as Norway, still clinging to the use of oats in brewing until the early part of the 20th century, the practice had largely died out by the 16th century, so much so that in 1513 Tudor sailors refused to drink oat beer offered to them because of the bitter flavour.[23][24]It's bitter deliciousness.
