There are a number of different theories as to the origin of the name 'Tripel'. One thing that is certain is that the modern use of the word came about in the 1950s when a well-known Belgian Trappist brewery renamed a beer they had developed in the 1930s.
Golden in colour and high in ABV, Tripels are brewed with Belgian yeast strains which lend the beer fruity esters and spicy phenolics. A dry finish and relatively high bitterness ensure Tripels are more drinkable than their strength would imply. Brew By Numbers brews Tripels with a large addition of aroma hops to give them extra flavour and to bring them into the 21st century.
