Grain bill option means that if you are ordering this grain for a particular recipe (lets call it grain bill #1)then the will place all the grains for grain bill #1 in the same bag. The grain bill is list of grains and their amounts for a given recipe.

So if you are ordering grains for different recipes, you can have all of recipe #1's grains put together (grain bill option 1), all of recipe #2's grains put together (grain bill option 2), etc.
