The best? That be Midleton's.
Midleton’s are all are triple distilled and have aged between 12 and 25 years in individually selected Bourbon or Sherry casks.
The aging in Sherry casks is an idea they got from Bushmill’s...Black Bush has been aged this way for many years (since 1934). The goodness of Black Bush is no doubt the reason the Master distiller chose to do this for Midleton’s Very Rare.
