After seven to ten years of aging in a barrel, bourbon whiskey is usually ready to be poured into your glass or drink straight out of the bottle. Teeling Whiskey Co. does it one better with their Vintage Reserve Single Malt Whiskey. Boasting some of the oldest single malt Irish Whiskey ever bottled, the Teeling Vintage Reserve Collection is crafted from 21 year old Irish Whiskey distilled in 1991 and matured in bourbon casks, then married in Sauterne wine casks for a unique flavor. Each cask was hand selected for quality and taste. Limited to only 5,000 bottles.
