Two Stacks announced the release of Single Grain Double Barrel, the latest offering now available nationwide through importer Foley Family Wines & Spirits

This is the first Two Stacks offering in the Irish Grain Whiskey category. It is available in both a 700 ml bottle and the unique 100 ml Dram in a Can.

As one of only three recognized whiskey bonders in Ireland when there used to be hundreds before the 1930s, Two Stacks is constantly on the hunt for traditional Irish whiskeys that will offer something beyond the ordinary, delving deep into heritage and lore. 

Two Stacks Single Grain Double Barrel exceptionally showcases the versatility and unexpected refinement of Irish Grain Whiskey, a very traditional style of whiskey most often used as a blending component. Here, the blending and double barrel aging allows this flavorful whiskey to step into the spotlight with exceptional character and value. 

“I think a lot of folks in Ireland thought we were mad when we told them we were coming out with an Irish Grain Whiskey,” Two Stacks Co-Founder Liam Brogan said in a news release. “We were confident with the right blend and aging/finishing we could produce something rather sophisticated and unexpected that honored the legacy of this workhorse stalwart in Irish whiskey history.”

While not as historically entrenched as the famed Single Pot Still whiskeys of the 18th and 19th centuries, the single grain style gained momentum with the advent of column stills in the mid-1800s. However, it wasn’t until the establishment of Cooley Distillery in 1987 and The Great Northern Distillery in 2015 (both founded by John Teeling, David Hynes, and Jim Finn) that the style truly came into its own in modern Ireland. The whiskey from those distilleries is blended and bonded for this bottling.

Two Stacks Single Grain Double Barrel starts with a mashbill of 94% maize and 6% Irish malted barley. The technical file for Irish Grain Whiskey requires that it is produced with malted barley (not exceeding 30%) and includes un-malted cereal grains, in this case corn. The small, but impactful, inclusion of 6% Irish malted barley brings subtle richness, enhancing the creamy, honeyed sweetness of the maize.

The distillate is first aged for 3-5 years in former bourbon barrels, followed by 1-3 years in Oloroso sherry casks, both in a traditional Irish rickhouse on the Cooley Peninsula, resulting in an 86-proof whiskey that is light and nuanced.

In addition to a 700 ml sustainable bottle made from 100% recycled glass ($44.99 MSRP), Single Grain Double Barrel is also available in a ground-breaking 100 ml Dram in a Can ($6.99 MSRP). Both products may also be purchased online https://twostackswhiskey.com/

The recyclable aluminum can provides added convenience for those wanting to enjoy a high-quality whiskey on the go. With the new embossed bottles, Two Stacks was one of the first spirit brands in the world to use 80% recycled glass, along with all-natural cork and recycled plastic seals.
