Step into the shadows with a session dedicated to the rich, bold, and mysterious world of dark beer. From silky stouts to roasty porters, we’ll uncover what makes these beers so beloved — from the unique malts that shape their flavour to the myths and memories they stir up. It’s a night for curious drinkers, flavour explorers, and anyone who’s ever felt drawn to the dark side of the beer spectrum.
