Irish whiskey brand Kinahan’s is returning to its roots with the release of a new whiskey made in bespoke handmade hybrid casks.

The Kasc Project is described as “the world’s first series of whiskies made in hybrid casks”. Each cask is made from a mix of five different types of wood, including unusual oak varieties and chestnut (Irish regulations, unlike Scotland, allow maturation in ‘wood’ rather than ‘oak’). The hybrid casks feature Portuguese oak, French oak, American oak, Hungarian oak and Chestnur, all of which helps create a blend of rich unusual flavours.

The first expression ‘Kasc Project’, described as “a riot of unconventional flavours”, comprises a blend of malt and grain whiskies, bottled at 43% abv with no chill filtration and without adding artificial colouring.

Zak Oganian, managing director, said: “This is an escape into the new ways of whiskey making. If you are a traditional whiskey drinker, this is not the whiskey for you. This is a daring and unconventional whiskey – it is a riot of wood.”

The Kasc Project is exclusively distributed through the UK by SEA Spirits and is available to buy from Master of Malt and The Good Spirits Co for £34.95 for 70cl.

Kinahan was established in 1779 and was originally known as the pioneer of Irish whiskey, according to the company. It earned its worldwide recognition for its focus on maturation as early as the 18th century.
