Additional guideline notes & competition context
These beers are brewed with 15% or more rice. Rice expression may vary in the beer, from neutral to very expressive and may exhibit flavor and aroma profiles of the specific rice varietal used, as well as a clean, dry finish. Hops should be integrated and not pronounced. Beers featuring a dominant hop or dry hop profile are classified into other hoppy lager categories.
