Up until 2013 the label always mentioned "Triple", as from 2014 (release: 2015) the word "Triple" on the label has been changed to "Quad". Story 1: This has always been a quadrupel, but the label designer was confused by the 3 X’s and had therefore changed the name to triple, thinking it was a mistake. (source: Facebook) Story 2: When brewed at Deca, the beer turned out a bit lighter in colour, so they called it a triple. Now that it’s brewed at the Struise’s own facilities, it’s more darker in colour and they call it a quad. (source: Carlo) Either way, it’s still the same recipe and should be treated as such.
