(bottle, as Maxbrauerei Porter, Bierkalender 4/2017, 5.8% abv) Slightly ruby brown colour with a beige medium-sized foamy head. Mildly dark malty and earthy aroma with leathery notes and mildly sour berry fruits. Sour and delicately sweet flavour, light to medium bodied with a tame carbonation. Slim dark malty start with sourish fruity notes of infection, leaving not much room for a real Porter character, except for some vaguely detectable earthy and leafy dark malty notes far in the background. Disappointing. 30.VI.17
