Fermenting Under Pressure. Pressurized fermentations are becoming increasingly popular, and for a good reason. Some of the benefits that you gain from fermenting beer under pressure are: Lower ester production, being able to ferment at higher temperatures without producing off-flavors, and having your beer carbonated by the end of fermentation (rather than carbonating separately for over a week!).
