I borrowed this idea from Boak and Bailey, who in turn took their inspiration from someone else. (http://boakandbailey.com/2015/01/proporval/) They reckoned that St Austell’s Proper Job could do with a hint of the wild Brettanomyces yeast as found in Orval. I added a third of a pint of Orval to two thirds Proper Job.
And while some may say this is a perfectly good way to spoil two good beers, I disagree. I found they meshed very well together. The hops of the Proper Job benefiting greatly from the addition of the Belgian esters. Give it a try yourself. Both beers are easily got and not too expensive so you’ve not got a lot to lose. I’m not much of a man for blending beers, Evil Twin’s Yin & Yang was the last I remember mixing and that’s what they were made for, who knows, this may have unleashed the mad scientist within me. Sláinte!
