Irish Single Malt Whiskey Irish single malt is similar to Scotch single malt in the way that both have to be made from a mash containing nothing but malted barley. They must be aged for at least three years in cask and the final product must come from one distillery, not a blend of distilleries. Apart from this there is obviously many differences between the two.
An interesting dram in the Jack Ryan Beggars Bush Irish whiskey range. The Bourdega is a medium-aged 15 year old single malt whiskey. After being matured in US oak, the whiskey is then finished in Sherry casks for extra flavour. Its bottled at 46% ABV.
