Nirvana Brewery Mocha Porter is among the darker, richer entries in the brewery's extensive low-alcohol range. The coffee character comes from two distinct sources: Midnight Oil, a concentrate from Climpson and Sons, and The Baron, a single-origin coffee from Daterra farm in Brazil. Brewed in Leyton, East London, it contains lactose and is not suitable for vegans. This is a 0.5% AF porter, sitting at the lower end of the alcohol spectrum.
