Like good wine, Unibroue’s fine beers have flavors that develop with age. Over time they become smoother, sometimes revealing notes of honey and candied fruit and developing a more assertive and lasting flavor. This phenomenon is known as “maderization” and is similar to the aging process of dessert wines like port.
Oxygen is the mortal enemy of beer because oxidation creates a stale, flat flavor. The yeast added to the bottle of Unibroue products triggers natural fermentation, consuming excess oxygen and preventing the beer’s CO2 from oxidizing. This enhances the beer’s aging potential. The high alcohol content of certain Unibroue products also lends itself well to aging by acting as a natural preservative.
Store bottles upright in a cool dark place at a stable temperature between 46ºF and 61ºF.
