You’ve been home brewing beer for a few years now and are ready to take your craft to the next level. Barrel aging your brews adds depth of flavor you just can’t achieve any other way. But barrels aren’t cheap, and you want to get the most bang for your buck. You’ve heard of people aging beer in used wine barrels, but what about hard liquor barrels? Can you put whiskey in a port barrel? The answer may surprise you.
What Is Port Wine?
What exactly is port wine? Port is a sweet red wine from Portugal made from native grapes like Touriga Nacional, Tinta Roriz, and Tinta Barroca.
Port gets its signature sweetness from the addition of brandy during fermentation, which stops the process and results in a wine around 20% alcohol. The wine is then aged for at least two years, often much longer, before bottling.
There are several styles of port, from approachable Ruby and Tawny to sophisticated Vintage and Colheita. Ruby port tends to be fruity, while Tawny port is nuttier from barrel aging. Vintage port, considered the pinnacle, is bottled from a single exceptional harvest and meant to age for decades.
Whether enjoyed on its own, in a cocktail, or paired with dessert, port wine is a delicious after-dinner treat. Its rich, layered flavors of red fruit, nuts and spice are best savored slowly.
So if you’re looking for a special wine to round out a meal or give as a gift, consider port. This historic, handcrafted wine from Portugal is a real taste of tradition.
The Unique Qualities of Port Barrels
Port barrels are made from oak and previously aged port wine, giving them a unique set of qualities that interact with whiskey during aging.
The Sweetness
The port wine soaked into the wood adds a touch of sweetness to the whiskey. As the whiskey ages, it absorbs these port wine compounds, resulting in tasting notes of dried fruit, nuts, and maple syrup.
The Ruby Tint
Whiskey aged in port barrels often develops a pinkish hue from the port wine’s anthocyanins. Don’t worry, the color is natural and won’t affect the taste. Some distilleries even add a bit of port wine to boost the color before bottling.
The Oak Influence
Although port barrels are reused, they still impart oak flavors like vanilla, spice and caramel. However, these oak notes are often more subdued compared to whiskey aged in new charred oak barrels. The port flavors tend to dominate.
An Elegant Balance
When done well, whiskey finished in port barrels achieves an elegant balance of oak, port, and spirit flavors. Notes of fruit, nuts, vanilla and spice all mingle together in harmony. The port qualities elevate the whiskey to a new level of complexity, perfect for slowly sipping and savoring.
Why Whiskey Is Often Aged in Ex-Bourbon Barrels
Whiskey is often aged in used bourbon barrels because the wood imparts flavors that complement the whiskey.
The Wood Matters
The type of wood used for the barrels significantly impacts the flavor of the aging whiskey. Bourbon barrels are made of American white oak, which gives whiskey flavors of vanilla, caramel, and coconut. The charred interior of the barrels also imparts a subtle smoky flavor.
It’s Been Seasoned
Bourbon barrels have already been used once to age bourbon, so the wood has been “seasoned.” The sugars, lignin, and other compounds in the wood have already been broken down, allowing the whiskey to absorb more complex flavors. The barrel’s pores have also opened up, allowing more interaction between the whiskey and the wood.
Cost-Effective
Ex-bourbon barrels are more affordable since they’ve already been used once. Whiskey makers can produce a quality, aged product at a lower cost by reusing barrels. The savings can then be passed onto consumers.
Tradition and Expectations
Using ex-bourbon barrels is also traditional for many whiskey styles. Consumers expect certain flavors, aromas and colors that can only be achieved using barrels that once held bourbon. Whiskey makers continue the practice to meet these expectations.
In the end, ex-bourbon barrels produce a whiskey with complex flavors and an amber color that consumers know and love. While other barrels could be used, bourbon barrels reign supreme due to their impact on the final product, as well as cost and tradition. The relationship between bourbon and whiskey is truly symbiotic.
The Flavor Implications of Using Port Barrels for Whiskey
Aging whiskey in used port barrels will impart rich fruity flavors. The port-soaked wood infuses notes of dried fruit like raisins, as well as sweet flavors of honey and toffee.
You’ll also detect hints of nuttiness from the oak itself, along with touches of spice. The port barrels tend to accelerate the aging process, so the whiskey can take on these complex flavors in a shorter period of time.
The result is a whiskey with deep ruby hues and a velvety mouthfeel. Each sip unveils layers of flavor that linger long after.
If you’re a fan of rich, decadent whiskeys, port barrel aging is a great way to experience an explosion of flavor in every glass. The port-infused flavors meld with the natural caramel and vanilla notes of the whiskey to create an utterly unique spirit.
Trying a port barrel-aged whiskey is a delicious way to explore innovative cask finishing and experience an unexpected blend of flavors in an all-new way.
Examples of Whiskeys Aged in Port Barrels
Some distilleries have started experimenting by aging their whiskeys in used port wine barrels. The port wine leaves behind flavors of dried fruit like raisins, prunes and figs that get imparted to the whiskey. A few examples of whiskeys aged in port barrels include:
Maker’s Mark
Maker’s Mark released a limited Private Select expression aged in port barrels that featured flavors of dark fruit, spice and toffee.
Westland
The Washington-based Westland distillery produces a port cask single malt with notes of cherries, plums, cocoa and coffee.
Teeling
The Teeling Whiskey Co. in Ireland finished one of their single malts in port barrels from Portugal. It has aromas of red grapes, sultanas and soft spice.
Glenmorangie
Glenmorangie’s Quinta Ruban is a 12-year-old single malt initially matured in bourbon barrels and then finished in port pipes from Portugal. It has a fruity, spicy flavor with hints of mint, rose and Turkish delight.
Aging whiskey in port barrels is an innovative way for distillers to create unique, complex flavors in their spirits. The port-influenced whiskeys tend to be fruity, spicy and perfect for after-dinner sipping.
The Pros and Cons of Aging Whiskey in Port Barrels
Aging whiskey in port barrels has some attractive benefits, but there are a few downsides to consider as well.
On the plus side, port barrels impart a ruby tint and flavors of dried fruit, nuts and spice to the whiskey. The port-infused whiskey often has fruity, jammy notes with hints of cherry, plum and raisin. Many whiskey drinkers enjoy the added complexity and layers of flavor from port barrel aging.
However, there are some potential drawbacks. The whiskey can become overly sweet from the port barrel, masking the underlying whiskey character. The port barrel aging also reduces the amount of whiskey that can be aged, as port barrels typically hold less liquid than whiskey barrels. More frequent barrel rotations may be needed.
Port barrel aging is an interesting experiment, but it may produce mixed results depending on personal tastes. For the curious whiskey explorer, it can lead to an exciting new discovery. But for purists seeking a traditional whiskey experience, standard oak barrel aging is probably your best bet.
In the end, whether or not to age whiskey in port barrels comes down to your own flavor preferences and how much you value tradition versus innovation. Both methods have their pros and cons, so you’ll need to weigh them for yourself. The only way to know for sure is to try some port barrel aged whiskey and see what you think!
Expert Opinions: Should You Put Whiskey in a Port Barrel?
The experts seem to agree that aging whiskey in used port barrels can impart some interesting flavors. However, it may overpower the original characteristics of the whiskey.
- Master distiller Jim McEwan believes aging whiskey in port casks can produce “fantastic results.” The port-infused oak barrels impart fruity, sweet flavors of raisins, plums and cherries to the whiskey. However, he warns that port barrels may dominate lighter, more delicate whiskeys.
- Whiskey expert Dave Broom notes that port barrel aging is “an interesting experiment” but the port flavors tend to “mask” the original whiskey characteristics. The results can be “a bit messy.” He recommends starting with a robust, full-flavored whiskey to stand up to the port influence.
- According to whiskey writer Charles MacLean, port barrel aging can yield a “complex and unusual” flavor. However, the port flavors tend to “overpower” the natural whiskey flavors. The longer the aging period, the more the port notes “take over.” He suggests a shorter aging time in port barrels to strike a balance.
In the end, whether or not to age your whiskey in used port barrels comes down to personal taste. If you enjoy bold, fruit-forward flavors in your whiskey, port barrel aging may appeal to you. If you prefer the natural characteristics of the whiskey to shine through, traditional oak barrel aging is probably your best bet. As in many things, moderation is key. A shorter time in port barrels allows you to experience the best of both worlds.
How to Source a Port Barrel for Your Whiskey
To age your own whiskey in a port barrel, you’ll first need to source an authentic used port barrel. Port barrels are typically made of oak and were previously used to age port wine, imparting rich flavors that also enhance aged spirits.
Find a Reputable Source
Purchase port barrels from established sources that properly prepare and seal the barrels after emptying. Check reviews to ensure quality and freshness. Local wineries or distilleries may sell or know of good sources. You want a barrel that will enhance your whiskey, not spoil it.
Inspect the Barrel
Once acquired, inspect the barrel for any leaks or damage before filling. The barrel should have a tight seal and solid construction. Give it a sniff—you should detect port wine aromas, not musty smells.
Consider the Type of Port
Ruby and tawny port barrels will impart different characteristics. Ruby port is fruity and robust. Tawny port is nutty and complex. Choose a barrel type based on the flavor profile you want.
Age and Sample
Fill your port barrel with unaged whiskey. Sample regularly, aging for at least 6-18 months. The whiskey will mellow and take on port wine notes with hints of fruit and nut. Bottle when it reaches your desired smoothness and complexity.
Aging whiskey in a quality used port barrel is a simple way to create a unique, flavorful spirit. With some patience, you’ll have a delicious whiskey infused with the essence of port.
