Exclusive | One shot of this rare whiskey costs $3,000 The Post taste tests the oldest Irish single malt ever sold

This is one swanky sláinte.Last month, Bushmills, the world’s oldest licensed whiskey distillery, released its limited edition, 46-year-old whiskey — billed as the oldest Irish single-malt ever sold.The mahogany sipper, hailing from County Antrim, Northern Ireland, also sports one hefty price tag for New Yorkers not worried about the volatile market and hoping for a taste.Bottles of the special spirit — officially christened “Bushmills 46-Year – The Secrets of the River Bush” — were originally priced at $12,500, and only 300 were made.

We’d order it — if someone else was paying for it.For a sobering comparison, a blip of the bougie booze at the Peninsula costs more than a night’s stay in the pricey property’s Executive Suite upstairs.The ritzy Midtown hostelry added a 2-ounce pour of the limited-edition whiskey to their menu on a rainy St.

Patrick’s Day, last month — which, incidentally, was the first and last time somebody gambled on the glam gulp sipping out of a rocks glass at the Clement Bar, the property told The Post.The luxurious tipple will...
