Answered by: Cassandra, An Expert in the Beer - General Category. The IBU's in beer refers to the International Bitterness Unit scale which is a standard for measuring the amount of hops in one's beer. For example, a hoppy beer like an IPA will have a very high IBU rating, like a 75, while a malty beer like a stout will usually (but not always) have a low IBU rating at around a 30. Really light beers will also normally have low IBU's.
