Virgin Oak casks are indeed charred as part of the maturation process. The charring of the casks plays a crucial role in imparting unique flavors and characteristics to the whisky.
When it comes to Virgin Oak casks, we at Deanston source our casks from the Kelvin Cooperage, a family-run cooperage based in Kentucky. The selection of the right casks is essential, as it sets the foundation for the quality and character of the whisky.
Before being transported to our distillery in Deanston, the casks undergo a toasting and heavy charring process at the cooperage. This process involves exposing the inside of the casks to an open flame, which results in the charring of the wood. The level of charring can vary, but for Virgin Oak casks, a heavy charring is typically employed.
The charring process has several effects on the wood and subsequently on the whisky that matures within. Firstly, it caramelizes the natural sugars present in the wood, creating rich and sweet flavors. This caramelization also contributes to the deep amber color that is often associated with Virgin Oak matured whiskies.
Additionally, the charring process creates a layer of charcoal on the inside of the cask. This charcoal acts as a filter, removing impurities and unwanted compounds from the spirit as it matures. It also provides a surface for interaction between the whisky and the wood, allowing for the extraction of flavors and aromas from the charred oak.
The level of charring can influence the flavors and intensity of the whisky. A heavy charring tends to result in more pronounced smoky, vanilla, and spice notes, while a lighter charring may allow for more delicate and nuanced flavors to develop.
At Deanston, our Virgin Oak casks are filled with our new make spirit, which is crafted using traditional methods and local barley. The casks are then placed in our unique, vaulted ceiling warehouse for maturation. This warehouse provides a conducive environment for the whisky to slowly develop and interact with the charred oak.
Virgin Oak casks are indeed charred as part of the maturation process. The charring adds depth, complexity, and unique flavors to the whisky, making it a sought-after choice for whisky enthusiasts. The Kelvin Cooperage and our warehouse at Deanston play vital roles in ensuring the quality and character of our Virgin Oak matured whiskies.
