From the official website:
The fact that Kilbeggan Distillery is alive and well is a testament to the people who live here today. The process used to distill the whiskey is a testament to the people who came before. The same pot stills from centuries ago are still on-site, and the whiskey still runs through a building erected well before the advent of electricity.

Kilbeggan® Single Pot Still is a glorious tribute to the town and those who kept its whiskey alive, proudly wearing the colour of County Westmeath on its label. It is the second limited release whiskey to be 100% distilled and matured at Ireland’s oldest licensed distillery, and the oldest expression to be released since distillation resumed at Kilbeggan in 2010. Double distilled, once through the oldest working whiskey pot still in the world, Kilbeggan® Single Pot Still is a unique mash of malted barley, raw barley, and 2.5% oats that was inspired by historical recipes from the distillery’s heyday in the late-1800s.

Nose: Initial fresh crisp aroma followed by apple, pear and melon. Jasmine and hazelnut notes combine with an almost honeycomb sweetness.
Taste: Spice becomes apparent but not overbearing with summer fruits and citrus. Warming mid palate with a fresh mint leaf flavour leading on to a rich creamy mouthfeel.
Finish: Initially soft, mellow and smooth with a creamy finish. Lingering spice and a dryness as the oat influence becomes evident.
