“Sleppingur” Cask Programme
The Sleppingur casks will be your unique opportunity to secure ownership of some of the very first whisky produced by Faer Isles Distillery.
AVAILABLE CASK TYPES
Bourbon
Bourbon is the most common cask type in the whisky world for a reason. It is the perfect match to malted barley, creating a stabile backbone and adding attractive flavours, most notably vanilla deriving from the American oak used. Known for creating a rich, sweet flavour profile due to the corn content.
Using ex Kentucky bourbon casks these barrels benefits from Char 3 charring, which brings out notes of vanilla, caramel, and spice. Matured aromas typically include coconut, licorice, honey and butterscotch. Spices such as nutmeg, cloves and cinnamon can appear with longer aging. Also, fruity notes such as apples, cherry and dried fruits.
The Missouri oak’s grain structure allows for steady maturation, adding depth while maintaining balance. In this cask, ASC Barrels’ meticulous wood selection meets Faer Isles Distillery’s distinctive new make, rich with grassy notes, light peat, and a mineral depth from surface pure water. The oak’s warm vanilla and spice wrap around the vibrant malt, allowing the fruit-forward fermentation to shine through while subtly integrating with the barrel’s caramelized sweetness. This partnership ensures a whisky where spirit and wood evolve together, creating a balanced and layered profile that fully honors both elements.

Sherry - Pedro Ximénez (PX)
Sherry is the second most common cask type in the whisky world. Very popular among enthusiast for the sweet and fruity flavours it adds to a whisky.
Crafted from Spanish oak and fed with Pedro Ximénez sherry, this cask carries the deep, syrupy flavors of dried figs, raisins, and chocolate. The medium toast helps refine tannins, giving a well-rounded structure while allowing the whisky to take on the intense, rich sweetness of its previous contents. Spanish oak has been prized for centuries in sherry-making, with coopers in Jerez perfecting their craft to create barrels that subtly enhance wine without overpowering it. The influence of this careful craftsmanship lives on in this cask, lending its refined depth to the whisky within. As it matures, Faer Isles’ vibrant malt spirit, with its gentle maritime influence, interacts with the cask’s residual sherry richness, enhancing both the whisky’s body and its lingering fruit complexity.

Sherry - Oloroso
This cask, previously filled with Oloroso sherry, brings complex and nutty character with hints of dried fruits like blackcurrants and prunes. The Spanish oak’s open grain allows for deep whisky interaction, creating a layered profile with rich mouthfeel. The history of Oloroso casks in whisky dates back to the early days of Scotch, when distillers sought out barrels from Spanish bodegas for their unique influence. A whisky aged in this cask will carry echoes of that tradition, with a balance of robust dryness and lingering warmth. Faer Isles’ new make spirit, with its savory hints of parmesan and fermented notes, integrates seamlessly with the cask’s oxidative depth, adding layers of umami richness and structure.

Tawny Port
A refined selection, this hogshead was seasoned with tawny port wine, imbuing the wood with notes of oxidized fruit, soft spice, and an elegant smoky depth. Sourced from the forests of central France, the French oak adds a fine tannic structure, making this cask ideal for maturing a whisky that carries a balance of dark fruit, toasted nuts, and a delicate dryness. Port-seasoned casks have long been favored by distillers seeking to add rich layers of complexity to their spirits, and this one, carefully sourced by ASC Barrels through its network of Portuguese and French cooperages, brings together the best of both worlds – refined oak and fortified wine influence. Here, Faer Isles’ vibrant malt, with its underlying exotic fruit notes of peach and pineapple, finds a perfect counterbalance in the barrel’s structured depth, creating a whisky with a velvety finish.

Moscatel
This cask, previously holding Moscatel wine, imparts a bright and tropical fruit influence, with clean aromas of floral notes and a touch of sucrosity. The light toast preserves the freshness of the wood’s character, allowing for a whisky that will develop into a vibrant, fruit-forward expression with a crisp yet rich finish. Moscatel, known for its floral intensity, has been a staple in Iberian winemaking for centuries, its barrels used sparingly but effectively in whisky maturation. This particular cask, selected for its excellent balance of sweetness and freshness, promises an elegant whisky with a lively yet nuanced profile. The floral and botanical qualities of Faer Isles’ new make, enhanced by its long fermentation, seamlessly merge with the cask’s honeyed influence, elevating both aroma and depth.

Banyuls
Once home to Banyuls, a fortified wine from the Mediterranean coast of France, this cask carries deep notes of sun-dried red berries, dark chocolate, and a hint of spice. The influence of the warm, coastal climate where Banyuls is produced gives this barrel a unique, ripe-fruit character that beautifully enhances whisky. French oak’s fine grain structure supports a smooth maturation process, allowing for a whisky that balances richness with a slight minerality. Carefully selected by ASC Barrels through its close ties with Southern French cellars, this cask is a rare find that adds depth and complexity to any spirit. The rich, velvety fruit profile from the cask melds with Faer Isles’ spirit, where earthy peat and maritime salinity play against the sweetness, giving the whisky a layered and expressive profile with an elegant oxidated complexity.

Carcavelos
A rare and historic cask, once filled with Carcavelos, a Portuguese fortified wine produced in limited quantities near Lisbon. In the 18th century, the Marquess of Pombal fiercely defended the reputation of Carcavelos, establishing one of the first regulated wine regions to preserve its bold character. This strength lives on in the wood, with the medium toast of the French oak enhancing the richness of the wine-soaked barrel, imparting notes of caramelized nuts, orange zest, and spiced honey. This cask represents a perfect balance between rarity and craftsmanship, wrapping Faer Isles’ new make spirit. Its minerality and subtle grassy notes interact beautifully with the cask’s orange and nut character, allowing the whisky to develop a refined, golden complexity over time.

NEOC®
The NEOC® (New Era of Cask) brings a meticulous approach to whisky maturation.
Originally used for premium French wines, these barrels undergo a precise
hand-shaving and re-toasting process – akin to the slow roasting of an
eight-hour lamb – to enhance their maturation potential. This method results in
a whisky with greater complexity of flavors and faster aging. Faer Isles’ new make, with its
botanical freshness, light peat, and mineral depth, finds an ideal partner in
the NEOC®. The cask refines the whisky with spice, elegant smoke, and an
extended length on the palate, allowing the flavors to unfold gradually. Each
sip reflects the synergy between Faer Isles’ bold spirit and ASC
Barrels’ expertise, resulting in a whisky that is both expressive and refined.

No two casks are the same. Even whisky on sister casks of the same type, filled on the same day, and stored next to each other in the same warehouse will develop differently due to the complex chemistry of oak barrel maturation and environmental factors. This is what makes single cask whisky a sought-after treat by connoisseurs.
Your cask will be filled with our unique new make spirit at 60-64% ABV. We will then store and mature your barrel for you for up to 10 years in our special “hjallur” storehouses for optimal maturation. For the first approx. 5 years of maturation we will use your chosen cask. After that, you will be able to choose a different cask for further maturation, ensuring that your cask is truly unique.
During maturation, your cask will be insured. You will get a certificate validating your ownership, and you will be able to get samples (see Terms & Conditions).

Your registration will be non-binding at first, since it must be followed up by a more formal commitment document that is sent out once we go through the waiting list. We will use the first-come-first-served principle, so registrations will be time-stamped. Listed people who do not complete the formal commitment document and make payment within the stated deadline will be deleted from the list.
