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.

The previous record for an aged single malt was 45 years, so Bushmills cracked the casket just in time to set a record.

“The casks will tell you when it’s time. We let each cask tell us when it’s ready and this whiskey told me it was ready,” Bushmills’ Master Blender Alex Thomas told The Post.
