It might not feel like St. Patrick's Day, but there are plenty of reasons (maybe more) to drink like an Irishman today. One unique option is this quarter-century-old expression from Glendalough. The single malt Irish Whiskey is the first of its kind to be aged in Irish Oak. The spirit was first matured in heavily charred ex-bourbon barrels before being transferred into an Oloroso Sherry cask and then transferred to the virgin Irish Oak. Only 1,800 bottles are known to man, so consider yourself more than lucky should you find yourself sipping some on this annual holiday.
