My wife asked me what the definition of beer was, and my best response was my understanding of Reinheitsgebot definition (which may or may not be correct).
- Malted Barley
This definition however excludes many things that I would also consider beer, for instance, the entire BJCP category 15 - German Wheat and Rye Beer, nor would it include beers with fruit or coffee beers, or winter ales (with coriander etc...)
So what is a good definition of beer? Is there one?
