It depends on the recipe, the strength, and how deceptive or not the alcohol might be in how the actual beer tastes. It could be any of the following:
1B. American Lager -- if the alcohol isn't strong, and it tastes "weak" for a malt liquor.
2A. International Pale Lager -- if it tastes "German" enough but not too strong.
4B. Festbier -- if it tastes very "German" and strong.
31B. Alternative Sugar Beer -- if it's just an American Lager with a buttload of extra sugar.
34B. Mixed-Style Beer -- if it's anywhere in between any two of the above.
