BeardedAvenger (1197) - Addlestone, Surrey, ENGLAND - JUN 12, 2017
Cask at PoW, Farnborough. Vaguest of vague sweet floral malty aroma. Glossy black on first sight, but more of a dark cola brown on closer inspection. Thin bubbly beige head. Light bitter, however there is a sweet and sour element underneath that. Weak coffee. Roasts. Berries. Boiled Veg. Light bodied, Watery. Light carbonation. Long finish. Nothing to write home about. Drinkable but ultimately uninspiring. jackl (8454) - Minneapolis, Minnesota, USA - JUN 4, 2016
