Boann Legacy Cask Strength is the 2026 Summer Solstice release from Boann Distillery in Ireland’s Boyne Valley, a single pot still Irish whiskey bottled at 59.2% ABV and limited to 777 individually numbered bottles. It takes the same intricate mash bill and seven-cask recipe as the standard Boann Legacy and strips away the dilution, presenting the whiskey at full cask strength for €85. Bottles went on sale from the distillery on Friday 19 June and, given the run size, will not last.
The interesting part is not the strength on its own. It is what the strength does to a whiskey already built on one of the busiest cask recipes in Irish whiskey.
What is Boann Legacy Cask Strength?
The core Boann Legacy arrived earlier this year as a permanent addition to the distillery’s single pot still range, bottled at 40% ABV for €55. The Cask Strength version is its Summer Solstice expression: identical liquid in composition, but bottled without reduction at 59.2%.
That liquid starts from a complex mash bill of malted and unmalted barley with oats and rye, the historic grain mix that defines true Irish pot still and which Boann has built its identity on reviving. It is then married across seven cask types: Bourbon, Oloroso, Pedro Ximénez, Palo Cortado, Amontillado, Moscatel, and French oak. Three sherry styles, a fortified Muscat, a Bourbon barrel and virgin French oak in a single bottle is unusual even by sherry-heavy standards.
At 40% the core Legacy reads as elegant and easy. At 59.2% the same components arrive with the brakes off, which is the whole point of the release.
Who is Boann Distillery?
Boann is an independent, family-run distillery in County Meath, founded by Pat and Marie Cooney and named after the Celtic goddess of the River Boyne, which runs past the site. Pat Cooney spent decades in the Irish drinks trade before selling the family’s previous business and building the distillery, and four of his children now work in it.
The distillery’s reason for being is single pot still made the old way. While most modern Irish whiskey leans on malted and unmalted barley alone, Boann has reintroduced oats, wheat and rye into its mash bills, grains largely abandoned in Irish distilling for half a century. It draws water from its own Boyne Valley well, sources grain from local farmers, and has pushed a vintage mash bill research project alongside whiskey historian Fionnán O’Connor to recover lost recipes.
It is also not a small player anymore. Alongside the Boann single pot still range, the distillery produces The Whistler whiskey portfolio and Silks Irish Dry Gin, and now exports to close to 70 markets. The Legacy name is a deliberate nod to the Cooney family’s fifty years in the Irish drinks industry as much as to Irish whiskey’s broader history.
Boann Legacy Cask Strength tasting note
These are the distillery’s tasting notes. We have not yet tasted this release ourselves, and will update with our own assessment and a rating once we have a glass in front of us.
Nose: Bold and immediately expressive, stewed orchard fruits and dark berries surging forward over generous caramel, with a clear warmth signalling the cask strength. Opens up considerably after a few minutes in the glass.
Palate: Rich and full-bodied, coating the mouth with a thick, almost syrupy texture. Caramel and dark fruit sweetness trade blows with pot still pepper and warming spice. A drop of water softens the heat and draws out further fruit and toffee.
Finish: Long and warming, spice and dried fruit lingering well after the last sip, with the high ABV leaving a satisfying glow. ABV: 59.2% | Cask type: Bourbon, Oloroso, PX, Palo Cortado, Amontillado, Moscatel, French oak | Price: €85 (700ml) (distillery notes)
What makes this release different
Most cask strength releases are about one cask or one style turned up loud. Legacy Cask Strength is the opposite: a seven-cask marriage where no single influence is meant to dominate, then bottled at full strength so every component reads at maximum intensity.
The mash bill matters here too. Oats bring a soft, almost oily texture, which is likely where that syrupy mouthfeel comes from, while rye adds the pot still pepper that the distillery’s notes flag on the palate. At 59.2% those textural and spice elements are amplified rather than rounded off, which is why water is doing real work in the glass rather than just taking the edge off.
For anyone who has found the 40% core Legacy pleasant but a touch polite, this is the version that should have the grip and concentration the recipe always promised.

Is it worth it?
At €85 for a 777-bottle, full-strength single pot still from one of Ireland’s most ambitious young distilleries, the pricing is fair rather than greedy, especially set against what allocated cask strength Scotch now costs. This is for the drinker who already likes Irish pot still spice and wants it at full volume, and for collectors who follow Boann’s solstice releases. It is less obviously a first Irish whiskey for a newcomer, where the gentler €55 core Legacy makes more sense.
