Four Walls Irish American Whiskey

In 2022, Glenn Howerton, Rob McElhenney, and Charlie Day, of the hit TV series “It’s Always Sunny in Philadelphia,” founded Four Walls Whiskey to donate all proceeds to financially support Pennsylvania hospitality workers affected by the COVID-19 pandemic. The first release was a commemorative 15-Year, single-barrel cask strength Irish whiskey made to celebrate the record-breaking 15th season of “Sunny”. Only 755 bottles of this premium package were released, which included signatures by Glenn, Rob, and Charlie, featured a mirrored, engraved box, and sold for $999. The second release was a 90-proof grain and malt Irish whiskey blended with Pennsylvania Straight Rye Whiskey, packaged in a collectible premium box with a retail price of $89. After the success of these limited releases, Glenn, Rob, and Charlie were inspired to create a permanent flagship release. After several test iterations, they developed an 80-proof grain and malt Irish whiskey sourced from the Great Northern Distillery in Ireland, and the Rye Whiskey from Cedar Ridge Distillery in Swisher, Iowa. The goal was to create an easy-drinking, affordable, and versatile Irish American whiskey that appealed to a wide audience. Let’s get started!

Nose

Upfront, there’s a nice mix of sweet caramel, butterscotch, and malt, followed by subtle apples and pears, with herbal notes of green tea, vanilla, a very nice floral note, lemon citrus brightness, toasted oak, and allspice. This profile leans on the caramel sweet side but has a good balance of malt and fruit, with underlying herbal notes and brightness, and a modest amount of toasted oak and allspice hanging underneath.

Palate

There’s a hint of smoke, malt, and caramel with apples, green tea, toasted oak, and a gentle amount of allspice. The mouthfeel is very good, and much more viscous than expected from an 80-proof whiskey. There’s less complexity here than on the nose, but there’s still a tasty mix of flavors in this very easy drinking profile.

Finish

A moderate amount of allspice continues with toasted oak, apples, while lemon citrus, vanilla, and floral return as the spice settles. The finish is on the short side as the spice fades away, leaving subtle tannins of lingering pipe tobacco

Conclusion

Four Walls has a flavor profile that’s more interesting than I expected. For the most part, the profile is what you’d expect, being 95% Irish whiskey. The 5% Rye whiskey contribution is subtle, yet noticeable. I’m not familiar with Cedar Ridge Rye’s profile, but Four Wall has some signature, tell-tale rye flavors. Particularly, the herbal and rye spice. I’m also picking up barrel characteristics, with more butterscotch and tannins that are typical of whiskey aged in new American oak. Because I’m too curious for my own good, I compared Four Walls with the original versions of Jameson, Bushmills, and Tullamore D.E.W.. I also compared Four Walls to Keeper’s Heart Irish + American, which I’ll discuss later.

Compared to Jameson, Bushmills, and Tullamore D.E.W., the 5% Rye whiskey in Four Walls had more of an influence than I originally thought, but still a very dominant Irish whiskey blend. Another takeaway was that Four Walls has a more flavor-intensive profile and a significantly better mouthfeel. I’m aware that everyone has their own palate, but I preferred Four Walls to the other three. The whiskey that came closest was Tullamore D.E.W. for its fruitier, brighter profile, which offered a good contrast. I’ve tried the original Bushmills before, but I didn’t recall it having such a strong lavender floral note that just wasn’t my jam. Jameson was the least complex and my least favorite.

Keeper’s Heart is an Irish-American whiskey brand from the Minnesota-based O’Shaughnessy Distilling Co., which launched its first release in 2021. Until their own distillate is ready, they’re sourcing their Irish whiskey from GND (same as Four Walls) and their rye and bourbon whiskeys from MGP, in Indiana. I compared Four Walls with Keeper’s Heart Irish + American whiskey (86 proof, $34.99). Keeper’s Heart doesn’t disclose its blend ratio of Irish to American whiskey, but it tastes like a 50-50 split, or close to it. MGP’s signature herbal rye notes are up front and center, compared to Four Walls’ dominant Irish whiskey profile. I also expected the higher ABV in Keeper’s Heart to give it an advantage, but the 6% increase in ABV didn’t make a difference. What the Keeper’s Heart had in herbaceous rye flavors, Four Walls made up for it in malt, caramel, and stone fruit. Because I’m a big rye fan, I liked Keeper’s Heart as much as Four Walls, but if American rye whiskey isn’t your thing, or you’re looking for more of an Irish whiskey profile, Keeper’s Heart may not be your best choice.

Four Walls is off to a good start. I would like to see them expand their lineup while continuing to offer high-quality and value-driven releases, including higher-proof and older-aged options, as well as wine or sherry cask finishes. If you already enjoy Irish whiskey in this price and proof range, Four Walls is a very good option that I’d recommend trying.
