St. Kilian 8-Year Celtic Pact II: Cask-Strength Islay Cask Release
Introduction & Overview
The Islay Cask Company introduces one of the oldest whiskies from the St. Kilian Distillery with the St. Kilian 8 Years Old 2017 Celtic Pact II Islay Cask Company 50 cl . Distilled in March 2017, this whisky is a rare expression matured for over 8 years, making it a landmark release for St. Kilian. Its production reflects the distillery’s Scottish-inspired tradition combined with meticulous cask selection, emphasizing authenticity and character.
Design & Presentation
This limited edition bottling is presented in the iconic St. Kilian pot still bottle, reinforcing the brand’s dedication to heritage and craftsmanship. True to the Islay Cask Company’s standards, the whisky is non-colored and non-chill filtered, highlighting a natural profile and transparency.
Maturation & Flavor Profile
The whisky was initially aged in ex-bourbon barrels before receiving a finishing period in a uniquely seasoned Oloroso sherry octave cask, previously used at Glenlossie and Deanston distilleries. This cask journey imbues layers of rich sherry influence, complementing the distillery’s original spirit. The bottling strength is a full 56.3% ABV, preserving the depth and intensity of the single cask maturation.
Master Blender’s Statement
Matthias Brückner of the Islay Cask Company reflects on the partnership with St. Kilian: “A few years ago, we could hardly imagine bottling a German whisky – until we discovered St. Kilian. Our first bottling, ‘Celtic Pact I,’ thrilled both us and our community so much that a follow-up became inevitable... ‘Celtic Pact II’ thus unites origin, history, and artisanal precision in a special way.”
Release & Availability
The St. Kilian 8 Years Old 2017 Celtic Pact II Islay Cask Company 50 cl is limited to just 112 bottles and will be released on 14 December 2025. It is priced at €69.90 for 0.5 l and available exclusively through Spiritory, offering collectors and enthusiasts a truly distinctive cask-strength single malt from one of Germany’s most respected distilleries.
