Mechanical bunging valve for beer pressurized fermentations
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)
Moreover, some research suggests beer fermentation under pressure can reduce the amount of advanced alcohol in beer and avoid having a headache after drinking.
Mechanical bunging valve can regulate pressure from 2 psi to 32 psi. (0.2bar~2.2bar)
