To age; to store, frequently while a slow after or secondary fermentation process under bunging pressure is taking place; lager means storage in German.
A class of beer made with a bottom-fermenting yeast strain. Usually fermented at cooler temperatures than ale and lagered (stored cold) after fermentation to drive off yeast by-products, usually resulting in a "cleaner" character in the finished beer.
