My first reaction at the article in this month's "What's Brewing", the CAMRA members paper, was that this must be a wind-up, but it seems not:
The people who brought you Cobra beer to drink with your curry are now using Belgian (Rodenbach) brewing expertise to produce an 8% abv, bottle-conditioned version of the beer. It's called King Cobra, comes in a black, Champagne-corked bottle, and retails at £3.99. It's brewed in Poland, then bottled in Belgium, apparently.
I can't wait to try one of those with a curry!
