Rabbit Hole Derringer is a Kentucky straight bourbon whiskey that undergoes a unique aging process to develop its distinct flavor profile. The aging process for Rabbit Hole Derringer starts with a base of a wheat mash bill, which sets it apart from other bourbons that typically use corn as the primary grain.
The whiskey is initially aged for a period of five years in #4 Char barrels. The use of #4 Char barrels is significant as it refers to the level of charring on the inside of the barrels. This char level helps to impart rich flavors and aromas to the whiskey as it matures. The five years of aging allows the whiskey to develop its character and complexity, as well as mellow out any harsh edges that may have been present in the younger spirit.
But the aging process for Rabbit Hole Derringer doesn't stop there. After the initial five years in the #4 Char barrels, the whiskey is then transferred to hand-selected sherry casks for further aging and finishing. This step adds another layer of flavor and complexity to the bourbon, as the sherry casks impart their own unique characteristics to the spirit.
The use of sherry casks for finishing is not uncommon in the whiskey industry. Sherry is a fortified wine that is often aged in oak casks, and these casks can add notes of dried fruits, nuts, and spices to the whiskey. The length of time that Rabbit Hole Derringer spends in the sherry casks can vary, but it is typically long enough to allow the flavors from the casks to integrate with the bourbon and create a more refined and balanced spirit.
The result of this aging and finishing process is a bourbon whiskey that showcases the best of both worlds – the rich, smooth flavors of a well-aged bourbon, and the complex, nuanced notes from the sherry casks. The wheat mash bill adds a unique twist to the flavor profile, bringing forth a slightly sweeter and softer character compared to bourbons that use corn as the main grain.
In my personal experience as a sommelier and brewer, I have had the opportunity to taste a wide range of whiskies, including those that have been aged in sherry casks. The influence of the sherry casks can vary depending on the specific whiskey and the length of time it spends in the casks. However, when done well, the sherry cask finishing can add an extra layer of depth and complexity to the whiskey, enhancing its overall flavor profile.
Rabbit Hole Derringer is aged for five years in #4 Char barrels and then finished in hand-selected sherry casks. This unique aging process creates a bourbon whiskey that is refined, balanced, and full of flavor. Whether enjoyed neat, on the rocks, or in a cocktail, Rabbit Hole Derringer is a whiskey that can be savored and appreciated by both bourbon enthusiasts and newcomers alike.
