Thanks for the memory... I’ve visited most of the Trappist breweries and/or met with the brew masters.
My favorite all time beer is the Westmalle Triple. (third from the left.)
LaTrappe is in Holland and I have not been there... but their beer is excellent.
Many times I have gone to the Beer Festival in the Brussels Grande Place that is held the first weekend in September... 300+ Belgian beers for three days... Every other year there is a Bruxellensis a week later that is for Belgian sours and farmhouse ales. Me I like a good stiff lambic like La Cantillon..
