What Wood is Used for Whiskey Barrels: Comparing The Choices

Whiskey-aging is has a long history and tradition, with the aging process playing a crucial role in defining the final flavor profile of your drink. We understand that the type of wood used for whiskey barrels is not just a matter of availability or cost, but a deliberate choice that impacts the taste, aroma, and character of the whiskey.

Predominantly, we love american oak for its unique properties that are ideal for aging whiskey. Oak’s tight grain, strength, and chemical composition allow it to hold spirits without leaking and to impart desirable flavors and aromas such as vanilla, caramel, and toasty notes. Other options are European oak, hickory, maple, chestnut, and cherry may.

Over time, we’ have observed that’ve tasted that different types of oak can influence the whiskey differently. For example, American white oak is commonly used for its sweetness and strong vanilla notes, while European oak tends to offer spicier undertones.

The charring or toasting of the inside of the barrel plays a pivotal role aging your whiskey. This process caramelizes the wood sugars, which in turn seep into the whiskey as it expands and contracts with temperature fluctuations during aging.

Origin of Whiskey Barrels

Historical Use of Wood in Whiskey Making

Historically, we have preferred oak for making whiskey barrels due to its durability and unique ability to improve the spirit for drinking. Of the different oaks, American white oak (Quercus alba) and European oak are the most commonly used. American white oak is especially prized since its less prone to leaking and imparts a distinctive flavor profile that includes vanilla, coconut, and caramel notes to the whiskey.

Are Wine Barrels Different?

Although both whiskey and wine barrels can be made of oak, the specifications and uses vary. Wine barrels tend to come in different sizes, reflecting traditional measurements like Bordeaux (225 liters) and Burgundy (228 liters) formats, and can be reused.

Whiskey barrels, however, are often made from new oak to comply with specific regulations, such as those for bourbon whiskey which require brand new barrels for the aging process. This dedication to using new wood for each batch contributes to the complexity and depth of whiskey’s flavor.


American White Oak Characteristics

American White Oak, often referred to by its species name Quercus alba, is highly regarded in the crafting of whiskey barrels due to its remarkable qualities.

Benefits in Whiskey Maturation

The superior physical properties of American White Oak not only make it a practical choice for barrel construction but also greatly enhance the whiskey aging process:

  • Durability & Waterproofing: Our American White Oak exhibits exceptional durability. Its wood cells possess tyloses, which render the wood waterproof, an essential trait for holding liquids over extended periods.
  • Flavor Contribution: During whiskey maturation, the barrel imparts a range of complex flavors to the spirit. Oak barrels are high in compounds such as tannins, which contribute to the whiskey’s structure and color. Furthermore, Quercus alba is rich in vanillin and lactones:
    • Vanillin offers sweet, vanilla-like notes.
    • Lactones are responsible for the characteristic woody, coconut notes. Lactones are more prevalent in American White Oak compared to other oak species.
  • Chemical Interaction: The oak’s interaction with the spirit is pivotal. American White Oak allows the whiskey to breathe through its pores, which promotes the oxidation processes, essential for mellowing the drink and enhancing its flavor profile.

We choose these materials and processes with care, considering how each contributes to the final product’s tastes and aromas.


The Best American Oak Barrels To Age With

Our favorite oak barrels to age with by far are the small and personal barrels made by Red Head Oak Barrels.

These are made in various sizes from 1-20 liters (and above if local). They are brand new american oak barrels that are primarily used for aging whiskey. They are also great for aging wine.

They are typically medium toasted and leave your whiskey with a great new flavor. I’ve had mine for a little over 6 months and love using it.

I have to say that new american white oak may be the best way to age whiskey in my opinion, but if you’re unsure you’ll just have to check it out yourself.


European Oak Varieties

When discussing European oak varieties utilized for whiskey barrel production, we primarily refer to two species: Quercus robur and Quercus petraea. These are the cornerstone species of European cooperage, known for their impact on the aging process and flavor profile of whiskey.

Here’s a comparison of some key characteristics:

Quercus robur and Quercus petraea both deliver unique qualities to whiskey. The choice of oak species is a critical decision for distillers, who must consider the desired flavor profile and maturation process. While both are commonly referred to as French oak within the cooperage industry, the nuances they provide are distinct and indispensable to the art of whiskey making.


How The Barrels Are Made

Influence of Barrel Size and Shape

The dimensions and geometry of whiskey barrels are deliberately chosen for their influence on the aging process.

  • Barrel Size: Smaller barrels expose whiskey to more wood surface area relative to volume, accelerating flavor infusion.
  • Barrel Shape: The shape determines the liquid-to-wood contact and can affect the rate at which flavors are extracted.

Impact of Toasting Levels

Toasting the interior of a whiskey barrel is a crucial step in its creation. It’s important to carefully control the intensity and duration of the heat applied to shape the final flavor profile of the whiskey.

  • Light Toast: Yields a subtle influence, preserving more of the whiskey’s innate character.
  • Medium Toast: Introduces a balance of caramelized sugars and deeper wood notes.
  • Heavy Toast: Dominates with pronounced caramel, vanilla, and spice tones.

Influence on Flavor From Different Wood Sources

  • Cherry and Maple Wood: Cherry wood imparts fruity, sweet flavors while maple can offer a smooth, buttery sweetness that can complement the traditional whiskey flavor profile.
  • Chestnut: This wood is known for contributing a dry, tannic quality to the spirit, which can add complexity to the whiskey’s finish.
  • Hickory: Hickory wood provides a bold, smoky essence to whiskey, reminiscent of what one might encounter with barbecued meats.
  • Acacia: This lesser-utilized wood offers floral and sweet vanilla notes, sometimes with a hint of spicy complexity.

The Flavor Effect Wood Has

When we store whiskey in barrels, the choice of wood plays a crucial role in shaping its final taste profile. Through years of tradition and scientific research, we have discerned that the interaction between the whiskey and the barrel’s wood generates a tantalizing array of flavors and aromas.

Oak is universally treasured for its positive influence on whiskey. Its porous nature allows the spirit to breathe, absorbing flavorful compounds such as vanillin (vanilla notes), tannins (dryness and astringency), and lignins (spicy and smoky qualities). Here, we explore how other woods contribute their unique characteristics:

The science behind this relates to the wood’s treatment before it meets the whiskey. Factors such as seasoning duration, intensity of toasting, and char level are meticulously controlled to ensure each wood type bestows its signature on the final product. We see that careful crafting and understanding of barrel wood can elevate whiskey to a complex and nuanced spirit, enjoyed by connoisseurs and casual drinkers alike.
