question: What is a good beer pairing for Hazelnut truffles?
answer: A great choice for Hazelnut truffles is I Wanna Be Your Dog (Omnipollo X BrewDog - Barrel Aged Imperial Stout.). Here's the recipe:
  This Omnipollo X BrewDog - Barrel Aged Imperial Stout. features a complex malt bill including Extra Pale (5.76 kilograms), Caramalt (1.2 kilograms), and Chocolate (1.08 kilograms). The hopping schedule uses Magnum (40grams @ 70), and American Oak Chips Medium Toast soaked in Speyside Whisky (50grams @ Wood Ageing) for balanced bitterness and aroma. Don’t be too quick to rack the beer off the yeast once your final gravity is reached. The stressed yeast will be absorbing a number of undesirable fermentation by-products such as acetaldehyde and diacetyl. Give them a minimum of 10 days at fermentation temperature to do this before cooling it down.
