It's A Sin is a Dutch imperial stout brewed in Middelburg by Brouwerij Kees in collaboration with Estonia's Pühaste Brewery. The name draws from Pühaste's 'Patt', meaning 'sin' in Estonian. At 13.8% ABV, this is a full-bodied, characterful stout built on coffee and chocolate, with a subtle spicy edge. The opening delivers deep coffee and cocoa notes, followed by a slightly warming finish. A substantial beer that works equally well as a dessert companion or standalone experience.

The core version is a thick, intense stout. Brouwerij Kees also releases a Barrel Project variant, aged in port casks, which adds elegant wine and oak dimensions beyond the standard expression.
