question: What is a good beer pairing for Pecan muffins with chocolate ganache?

  A collaboration with Omnipollo, known for their uncanny ability to repilcate dessert flavours in indulgent beers. This caramel and pecan flavoured imperial stout has been barrel aged for almost a year in whisky casks, to add an extra level of depth to the pecan mud pie concept.
  ABV: 12% | IBU: 55
  Malts:
  - Extra Pale (5.76 kilograms)
  - Caramalt (1.2 kilograms)

  - Flaked Oats (0.72 kilograms)
  - Extra Dark Crystal (0.48 kilograms)
  - Brown (0.48 kilograms)
  - Dextrin Malt (0.48 kilograms)
  - Double Roasted Crystal (0.24 kilograms)

  Hops:

  Yeast: Wyeast 1056 - American Ale™

  Tip: 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.
