Bottle from Drinkmonger, Bruntsfield, Edin. Cloudy yellow. Thin head that goes away promptly. Aroma has yeasty, Saison notes with some serious funk! Fruit salad sweets. Bit sweaty. A wee hint of the musky, slightly smokiness of the vanilla pods. Taste is sharp with more, softer this time, sour character. A hefty dose of the bitter rhubarb addition comes through midway. Bit of acrid puke! Some rather harsh medicinal notes. Tart, juicy finish. Medium to lightish body. Medium carbonation. Bit too much for me.

Though this one had slipped the net, so good to finally get my paws on it. Hazy gold beer, good pale cream colour head. Palate is light and fairly dry. Good fine carbonation. Good fresh rhubarb kicks off, tangy. Some bitterness creeps in, traces of orange and tangerine peel. A nice light vanilla before a crisp finish. Overall impression is indeed quite Rhubarb and Custard like but with a light bitterness. Good invention again by the mad ones.
