Tripel is a term used by brewers or people mainly in the Low Countries, some other European countries, and the U.S. to describe a strong pale ale, loosely in the style of "Westmalle Tripel".
 The origin of the term is unknown, though the main theory is that it indicates strength in some way.
 It was used in 1956 by the Trappist brewery, Westmalle, to rename the strongest beer in their range, though both the term Tripel and the style of beer associated with the name (strong pale ale), were in existence before 1956.
 The style of Westmalle's "Tripel" and the name was widely copied by the breweries of Belgium, and in 1987 another Trappist brewery, the Koningshoeven in the Netherlands, expanded their range with a beer called "La Trappe Tripel", though they also produced a stronger beer they termed "La Trappe Quadrupel".
 The term spread to the U.S. and other countries, and is applied by a range of secular brewers to a strong pale ale in the style of "Westmalle Tripel".
The Bass Brewery was founded in 1777 by William Bass in Burton-upon-Trent, England.
 The main brand was Bass Pale Ale, once the highest-selling beer in the UK.

 Its pale ale was exported throughout the British Empire, and the company's distinctive red triangle became the UK's first registered trademark.
