18 years. Limited Reserve. Jameson — the apex of the standard Jameson age-stated range, presenting the world's best-selling Irish whiskey at 18 years of maturation in hand-selected American barrels and European oak casks, finished in first-fill bourbon barrels for the final maturation period.Jameson has been triple-distilled at the Midleton Distillery in County Cork since the brand's revival there in 1975. The 18 Year is produced in limited quantities compared to the ongoing standard range — a mellow, rare expression that requires the patience of extended maturation applied to one of the world's most consistently produced whiskeys.Where the standard Jameson and 12 Year are blends of pot still and grain whiskey, the 18 Year draws on the finest hand-selected barrels from the Midleton warehouses meeting the specific character profile of extended maturation — richer, silkier, more complex than any younger Jameson expression.Tasting Notes Nose: Dried fruit, vanilla, leather, toasted wood, light spice Palate: Rich dried fruit, toffee, vanilla, warming spice, creamy mouthfeel Finish: Long, smooth, honeyed and spiced Specs Distillery: Midleton Distillery, County Cork, Ireland Style: Blended Irish Whiskey (Pot Still + Grain) Age: Minimum 18 years Finish: First-fill bourbon barrels ABV: 40% Size: 750ml Browse all Irish whiskey at Wooden Cork.Frequently Asked Questions How does the 18 Year differ from the standard Jameson range? The standard Jameson is a blend of 4–7 year whiskeys for consistency and volume. The 18 Year draws on the finest aged barrels from Midleton's inventory meeting an 18-year minimum, producing the richer, more complex character that extended maturation in high-quality casks develops. What does first-fill bourbon finishing add? First-fill bourbon casks — used only once before — impart more vanilla, caramel, and toasted oak character than refill casks. Applying this as a final finishing step adds fresh bourbon cask influence on top of the primary maturation's developed character. {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"How does the 18 Year differ from standard Jameson?","acceptedAnswer":{"@type":"Answer","text":"Standard Jameson blends 4-7 year whiskeys for consistency and volume.
