BJCP 31A
A base beer enhanced by or featuring the character of additional grain or grains. The specific character depends greatly on the character of the added grains.
If the alternative grain does not provide a noticeable distinguishable character to the beer, enter it as the base style. This style should not be used for styles where the alternative grain is fundamental to the style definition (e.g., Rye IPA, Oatmeal Stout, Rice- or Corn-based International Lager). Note that sake is not beer, and is not intended for this category.
