Iwai whiskey is aged for a period of 3-12 years, with an average age of 5 years. This aging process plays a crucial role in developing the flavors and characteristics of the whiskey. The whiskey is primarily aged in ex-bourbon and ex-sherry casks, which are known for imparting unique flavors and aromas to the spirit. Additionally, there may be some incorporation of wine, port, and new oak barrels to ensure consistency in the final product.
The use of ex-bourbon casks in the aging process brings forth notes of vanilla, caramel, and oak, which are commonly associated with American bourbon whiskey. These flavors can add a rich and sweet complexity to the Iwai whiskey. On the other hand, the ex-sherry casks contribute to fruity and nutty undertones, as well as a hint of spiciness. This combination of cask types creates a harmonious balance of flavors that make Iwai whiskey unique and enjoyable.
It is worth mentioning that the use of wine and port casks in the aging process can add different dimensions to the whiskey. The influence of these casks can introduce fruity and sometimes even floral notes to the final product. This experimentation with different cask types showcases the creativity and innovation of the distillers, as they strive to create a whiskey that stands out from the rest.
New oak barrels may also be incorporated in the aging process. These barrels, which have not been previously used for aging other spirits, can contribute intense flavors of oak, spice, and tannins. The use of new oak allows for greater control over the maturation process and can result in a more robust and bold whiskey.
In my personal experience, I have found that the aging process of Iwai whiskey plays a significant role in its overall quality and complexity. The flavors and aromas that develop over time add depth and character to the spirit, making each sip a delightful experience. The use of different cask types further enhances the whiskey's flavor profile, creating a unique and memorable drinking experience.
To summarize, Iwai whiskey is aged for an average of 5 years, with a range of 3-12 years. The aging primarily takes place in ex-bourbon and ex-sherry casks, with the addition of wine, port, and new oak barrels for consistency. This careful aging process allows for the development of a complex and flavorful whiskey that is truly a delight to savor.
