 But it's lagered, so it's made at higher temperatures, and then they cool the temperature down and store it for a long period of time. And by storing it for a long period of time, the yeast are still working, but they're working very slowly. They can't leak because they're all tightened up because they're nice and cold. And so they're just chewing up the old off flavors that are out there and getting rid of them. So they're cleaning up the beer.
