Barrel-aged whisky is built on three key elements: whisky, oak, and time. As whisky rests in barrels, it changes in flavour, aroma, colour, and even mouthfeel. At Hunter & Barrel, our focus is rooted in the primal, rustic things in life. Cooking meat over hot coals; honouring traditional culinary techniques; and using the aging process to inject more flavour and depth into our food and drink. We’ve mastered the art of barrel-aging our whisky, and made this guide to cover the fundamentals in a clear, practical way.
What Is Barrel-Aged Whisky?
Whisky is a spirit distilled from grain, then aged in wooden barrels, usually made of oak. Barrel-aged whisky refers to varieties in which the oak is a key component. The barrel adds to whisky in three main ways: it deepens and complexifies the flavour, changes the colour, and often softens the texture.
How Whisky Matures in Barrels
As the whisky rests in the barrel, the wood pulls colour and flavour compounds from the wood, resulting in a product that feels less sharp, tastes richer and smoother, and introduces new notes to the flavour profile. These flavour compounds often manifest as vanilla, caramel, coffee, and tobacco, among other floral and spiced notes.
The temperature and humidity of the barrel’s location also play important roles. In warmer climates, whisky often ages faster, while in cooler ones, the process is more gradual.
Types of Barrels Used for Aging
Different woods significantly affect the final flavour. The most commonly used oaks include American white, French, and Japanese. Each variety has different porosity, wood sugar levels, and chemical compositions that affect how the spirit and the wood interact.
Additionally, some oaks are ‘charred’ to varying degrees to further control the amount of oxygen allowed through the cask, thereby impacting flavour and ageing time.
Key Characteristics of Barrel-Aged Whisky
When trying a barrel-aged whisky, there are a few key factors to note, namely: flavour, colour, and aroma. Identifying these will help sharpen your tasting skills and pair the right kind of food with your whisky.
Flavour Profiles to Expect
As mentioned previously, the most common flavour notes you’ll notice in barrel-aged whisky are:
- Vanilla, caramel, cinnamon, tobacco and other spices
- Toasty and smoky notes
- Subtler hints of fruit, nuts, coffee or chocolate
Most barrel-aged whiskies will have a mix of these flavours, depending on the ageing time and type of barrel. Shorter ageing often keeps a more traditional whisky taste — lighter, sharper, and balanced. Whereas a longer ageing process develops a sweeter, more spiced flavour in the whisky.
There’s a fine line to ageing, as leaving the whisky to age for too long can result in an unpleasantly woody, sawdust-like taste, while not ageing it long enough often results in no noticeable change at all.
Aroma and Nose Characteristics
Aroma usually reveals a drink’s notes before the first sip. Flavours like citrus, smoke, or vanilla are generally apparent in the scent of a whisky, while other notes like coffee, chocolate, or nuts are harder to notice until you taste it.
To pick up the aromas of a spirit, hold the glass just below your nose and breathe in slowly and deeply. Ask yourself which scents are most prominent and what the whisky’s character is: smoky, sharp, candied, or floral. It takes time to hone your nose to the subtle intricacies of each whisky, but with practice, it will become second nature.
Colour and Appearance
Whisky is naturally amber, but barrel ageing can drastically alter the colour. A darker shade points to one of two things: a tannin-rich oak variety, or a longer ageing period. While it’s hard to gauge quality simply from colour, when paired with the other qualities mentioned, it gives an idea of the whisky’s style and production method.
How to Age Whisky in a Barrel at Home
Now that we’ve covered what it is, let’s talk about how you can age whisky in a barrel at home. While distilleries are often kitted with specialty machinery and rows and rows of barrels, the basic idea of barrel ageing is quite simple.
You’ll need a food-safe barrel, an unaged whisky, and a dark place to store it. That’s it!
Choosing the Right Barrel Size
The size of your barrel matters. A small whisky ageing barrel behaves very differently from a larger one, as more wood surface area is in contact with the spirit. This leads to faster flavour transformation and therefore a shorter ageing period.
For DIY ageing, we recommend a barrel capacity of 1–5 L, which translates to an ageing period of anywhere between 2 and 12 months. Anything larger, and you might be waiting upwards of 24 months for your aged whisky.
Tips for Optimal Ageing Conditions
The best location to store your barrel is a cool, dark place. Somewhere with a stable room temperature, with some way for air to get in and out. A cellar, basement, or garage is perfect for this.
It’s vital to taste small samples of your whisky regularly. Note the colour, aroma, and flavour each time, and once it’s at a place that you’re happy with, empty the barrel into sanitised glass bottles and seal them.
