Unibroue beers are manufactured from natural ingredients only, namely water, malted barley, malted or raw wheat, corn, spices, sugar and yeasts. Unibroue uses state-of-the-art equipment and rigorously follows each step of the manufacturing of its beer.

The brewing methods used by Unibroue have been inspired by the great European brewing traditions and, in this respect, are one of a kind in North America. The methods used stand out, in particular, from the brewing methods of the mass-producing breweries and even from the other North American craft brewers because the beer is refermented in bottles and partly-clarified only. Through these methods, specialty beers with an evolutive taste and a long shelf life are produced. The manufacturing of the beer at Unibroue is done in five phases: brewing, fermentation, clarification, bottling and kegging and, finally, refermentation in bottles in the holding room.

It is unnecessary to add preservatives or to pasteurise the beer, a process that makes the beer sterile and without a soul.

The brewing of Unibroue beers is divided into five sequences:
Brewing
Fermentation
Clarification
Bottling or Kegging
Refermentation in Botlles
Quality Control
