Brains Dark is produced by the S.A. Brains brewery in Cardiff and was the original mainstay to the Brains range. It is a relatively weak mild ale (3.5% ABV) with a very odd chocolate/nutty taste to it, and is quite sweet (to my tastes anyway, but I'm a bitter drinker so ...).

Dark is the current holder of the CAMRA "Champion Mild of Wales" award
