 And a ale yeast can do its job above 75. However, they work best in those other ranges. So can I ask a question then? Obviously, and maybe you're going to give this up later, so I'm getting a little ahead of myself, but it's like, what are the benefits of having those two different temperature ranges as the yeast are working? This is exactly the next thing I was going to talk about. So excellent lead in. Thanks. So there is a relationship between the temperature of fermentation and the flavor that you get.
