Belgium - Breweries

Westmalle Brewery (Brouwerij der Trappisten van Westmalle) is a Trappist brewery in the Westmalle Abbey (Belgium) that was founded in 1836. Westmalle Tripel is credited with being the first golden strong pale ale to use the term Tripel.
As with all Trappist breweries, Trappist beer is brewed within the walls of a Trappist monastery, under the control and responsibility of the community of monks, who are involved through the process of making and marketing the beer. The beer is sold only for financial support of the monastery and good causes. The majority of the profit from the sale of the beer is distributed to charities and for community development around the region.

Over the years the brand identity is updated and re-launched with subtle changes, a change of Logo or a new font.
Sometimes this brand update is done by the new owners after a brewery has been sold, other times just to give the brand a fresh new look on the ever growing market.

Below are some notes to help identify some of these changes and an aid to reference the year of the glass.
