question: What is a good beer pairing for Chocolate, cherry and hazelnut mousse?
answer: A great choice for Chocolate, cherry and hazelnut mousse is AB:19 (A Blend of Two Barrel-aged Imperial Saisons.). Here's the recipe:
  One of the most complex beers we’ve ever attempted. A blend of two barrel-aged Imperial Saisons – one black, one red – which has in turn then been aged in rum barrels, it is an enormous, intricate beer. A baseline of warm, smoky raisin and plum, followed by punchy flavour elements coming to the fore – coconut, mint and blackcurrant. There’s a long undercurrent of treacle toffee, before the finish darkens to liquorice, star anise amidst a touch of honey sweetness.
  ABV: 13.1% | IBU: None
