Found in the garage, home brew 5-8 years old. No idea what it is. Only clue is RBW on the cap. Made with water drawn from the Hascombe fountain after dark. Colour dark amber, nose malty Flavour: initially sweet malty over tones, replaced with mild stout flavours. Still with that unusual lager fizz. I'm going to claim it is a dark lager. Surprisingly drinkable.
