Proper No. Twelve Black Reserve: Bold Irish Whiskey from Charred Bourbon Casks

Proper No. Twelve Black Reserve: Bold Irish Whiskey from Charred Bourbon Casks
Proper No. Twelve Introduces Black Reserve for a Bold Irish Whiskey Experience
Proper No. Twelve Back Reserve extends the Proper No. Twelve lineup with a new expression featuring a blend of single malt and grain whiskey, matured for at least four years. This release highlights the influence of heavily charred bourbon barrels, delivering enhanced depth and intensity in the spirit. As part of a renowned legacy from the world's oldest licensed whiskey distillery, it offers an accessible yet robust option for both new and seasoned Irish whiskey enthusiasts.
Maturation & Flavor Profile
The whiskey matures in level 3 heavily charred American Oak bourbon barrels, combining both first-fill and second-fill casks. The heavy charring opens the tight grain of the American White Oak, imparting pronounced caramel, toasted wood, soft vanilla, and sweeter notes. Second-fill barrels contribute traditional Proper No. Twelve character with additional vanilla, toffee, and spice nuances. This thoughtful maturation creates a rich, intense flavor profile while retaining a smooth approachability.
Master Blender's Statement
Lander Otegui, Executive Vice President of Marketing and Innovation at Proximo Spirits, emphasizes that Proper No. Twelve Black Reserve builds on the brand’s foundation of craftsmanship and tradition. He highlights the synergy between the toasted wood, caramel notes, and vanilla sweetness as a testament to their production expertise.
Tasting Notes
• Nose: Rich caramel and toasted wood with soft vanilla undertones
• Palate: Intensely bold bourbon flavors enhanced by sweetness and spice
• Finish: Smooth with lingering toffee, vanilla, and gentle spice
Release & Availability
Proper No. Twelve Back Reserve is bottled at 40% ABV and offered in a 700ml bottle. It is priced at approximately €33.00 SRP and available now through Spiritory. This expression suits neat drinking, on the rocks, or in cocktails such as the Proper Black Honey Old Fashioned, where a hint of honey complements its vanilla and wood-derived sugars.
Whether for St. Patrick’s Day or everyday enjoyment, Proper No. Twelve Back Reserve invites whiskey lovers to experience a fresh take on Irish whiskey craftsmanship.
