I know I read this somewhere once but can't seem to find it. When a base malt profile (Munich malt for instance) says something like "80% max in batch", is that 80% of total grain bill, even if that malt is your only base malt (other 20%+ are specialty malts), or does that mean that you need another base malt (say, a pale 2-row) to make up a total base malt bill?
