From Château Léoville Barton to Rhum Agricole, taking in a combination of Tequila and mezcal, these are some of the most strange and sensational cask-finishes used to mature whisky you’ll find at MoM Towers.

Cask-finishing has become a popular phenomenon in the whisky industry over the last couple of decades as experimental producers seek to add a touch of something different and delightful to their distillates. But despite there being a glut of great expressions on the market that benefit from secondary maturation already, there’s always room for innovation and this leads some to choose a road that’s less travelled, but very rewarding.

To celebrate those who dare to do it differently, we’ve decided to shine a light on some of the most unusual cask-finished whiskies around. Enjoy the selection!

Glen Moray Rhum Agricole Cask Finish Project

Glen Moray loves a good experiment, to the joy of fans of all things unusual and writers who need ideas for a blog like this. The distillery in Speyside has finished this single malt Scotch whisky in casks that previously held rhum agricole from Martinique for around 24 months, a style that should bring a lot of grassy, fruity sweetness to the dram.

What does it taste like?:

Candied lemon peel, honey, white pepper, toffee apple, dried grass, toasted brown sugar, walnut, cherry and banana.

J.J. Corry The Battalion

From Chapel Gate whiskey bonders comes J.J. Corry The Battalion, a blend of 60% grain and 40% malt whiskey that was initially aged in bourbon casks. Then the grain portion continued its maturation in a combination of Tequila and mezcal casks for seven months, while the malt portion continued maturing in just mezcal casks for seven months. Ever had a whiskey matured in both Tequila and mezcal casks? Of course, you haven’t! This bottling gets extra badass brownie points for being named after the Battalion San Patricos, a group of Irish soldiers who fought for Mexico in the Mexican-American war

What does it taste like?:

Fresh leafy notes, apple skin, tangy pineapple, ripe pear, green grass, vegetal agave, oak spice, sea salt, dried herbs, lemon curd and a slight oily nutty note.

Talisker 2007 (bottled 2017) Amoroso Cask Finish – Distillers Edition

The Distillers Editions from Talisker are always sure to deliver some true delights and this expression is no exception. Finished for a period in casks that previously held amoroso (a blend of oloroso and sweet Pedro Ximénez)  sherry, the profile pairs wonderfully with the distinctive maritime salinity of this single malt.

What does it taste like?:

Toffee, seaweed, a sharp hint of fresh citrus fruit, milky coffee, juicy pineapple, apple and some light vegetal hints of fresh thyme and basil balanced by a kick of sea spray, lingering smoke and dried fruit.

Penderyn Madeira Finish

Not many brands would make its original ‘house style’ such a distinctive profile, but then Penderyn has proved itself to be quite the experimental distillery since it first began distilling back in September 2000. This bottling was aged initially in ex-bourbon barrels before it was finished in ex-Madeira wine casks, an idea that speaks to the influence the late Dr. Jim Swan had on the Welsh whisky makers.

What does it taste like?:

Herbs, vanilla sweetness, resin, sultanas, toast, over-ripe grapes, custard and stem ginger.

Glenfiddich Experimental Series – IPA Cask Finish

You’d expect Glenfiddich’s Experimental Series to have a few single malts with a point of difference and this IPA Cask finish doesn’t disappoint. Created from a collaboration between Glenfiddich Malt Master Brian Kinsman and IPA expert Seb Jones, the IPA which was in the casks before the whisky was specially brewed for this expression by the Speyside Craft Brewery.

What does it taste like?:

Fresh green apple, William’s pear, spring blossom, aromatic hops, fresh herbs, zesty citrus and creamy vanilla.

Midleton Method and Madness Single Pot Still

Another highly innovative series from an exceptional distillery, Method and Madness Single Pot Still was perhaps the most intriguing release from the first batch of Midleton’s experimental range. You won’t find many single pot still whiskies, matured initially in ex-sherry and bourbon barrels and finished in French chestnut, believe us!

What does it taste like?:

Red liquorice laces, fresh rosemary mint, grated root ginger, sweet fruit, aromatic green tea, cinnamon toast, rich wood and ripe banana.

Jefferson’s Grand Selection Château Pichon Baron Cask Finish

Jefferson’s Grand Selection range demonstrates that the Americans are no strangers to the joys of cask-finishing with a selection of excellent Jefferson bourbons finished in a variety of wine casks. This particular bottling was finished for a period in casks that previously held Bordeaux red wine from Château Pichon Baron, and it’s as downright delicious as it sounds.

What does it taste like?:

Red apples, raspberries, buttered corn, honey, heavy cinnamon heat, fresh floral notes and dense red berry elements supported by waxy peels and earthy oak.

Green Spot Château Léoville Barton

This beauty is certainly a treat. We’re always suckers for all things Spot (Red, Yellow, Green – they’re all great), but this happens to be the first-ever single pot still Irish whiskey finished in Bordeaux casks! The Bordeaux wine takes its name from the Irish wine merchant Thomas “French Tom” Barton and the grand cru Château is still run by his descendants to this day, so this is a real celebration all things awesome and Irish.

What does it taste like?:

Wild raspberry, a little potpourri, crab apple, toffee, lemon peel, warming spice, vanilla, honey and gingerbread.
