There is of course beer recipes but what makes it different from a hop bill? Do you use a hop bill for all types of beers? What do you consider when making one?
The term "Bill": be it grain or hops is simply the list of that type of ingredient, weight and time or stage schedule and how it's applied to the recipe.
Sample: 2oz Galaxy FWH
( weight, ingredient, added to kettle allowing the first wort of the sparge to mix with the hops, hops stay in for full duration of the boil)
Yes all beers have a grain and hop bill, technically. Even if each bill just has one ingedient.
