Hyde No. 8 Stout Cask finish is a blend of 75% 4 year old single grain, matured in a first fill flame charred bourbon cask and 25% 4 year old Single Malt, matured in a toasted Oloroso sherry cask. This is a collaboration between The Cotton Ball Brewing Company in Mayfield, Cork and Hibernia Distillers (Hyde). The blend is vatted and then transferred into a craft Irish stout infused ex-bourbon Oak cask for 5 to 6 months. The stout was previously aged in the cask for 3 months to infuse flavour before laying down the whiskey.
