Design your own "Stout" beer. Include the malt and grain components and their percentages of each.
In the late 1600s to early 1700 the word “stout” used to refer to strong beers. It is the dark beer made up made by using roasted malt or roasted barley, hops, water and yeast and in beer-making, a simple pale ale might contain a single malted grain, while a complex porter may contain a dozen or more ingredients.
Mash ingredients, mash bill, grain bill , or mashbill are the materials that brewers use to produce the wort as they then ferment into alcohol. Mashing is process in which act of creating and extracting fermentable and non-fermentable sugars and flavor components from grain by steeping it in hot water, and then letting it rest at specific temperature ranges to activate naturally occurring enzymes in the grain that convert starches to sugars. The sugars separate from the mash ingredients, and then yeast in the brewing process converts them to alcohol and other fermentation products.
Stout malt is a base malt for stout beer which is light in color and it is prepared so as to maximize diastatic power in order to better-convert the large quantities of dark malts and unmalted grain used in stouts.
In practice, however, most stout recipes make use of pale malt for its much greater availability. ASBC 2-3/EBC 4–6, DP 60–70 °Lintner.
