Milam & Greene Whiskey is unleashing Gray Wolf Straight Bourbon, a blend of two six-year-old, cask-strength collector’s edition bourbon casks. This first release in the 2025 Wildlife Collection will be available exclusively on the Milam & Greene Whiskey website and for the first time ever, available for online purchase to pick up at the distillery tasting room beginning at 3:00 p.m. (CDT) on Wednesday, March 26, 2025.

Gray Wolf is the first release in the Milam & Greene 2025 Wildlife Collection, which explores how climate impacts the final flavor of aging bourbon. 

“The Wildlife Collection is more than just an incredible collectors’ bourbon, it is also an opportunity for us to test how climate impacts the aging of whiskey,” Heather Greene, Milam & Greene Whiskey master blender and CEO, said in a news release. “Whiskey barrels aging in our rickhouses are open to natural airflow, letting the Texas weather make its mark on it. The Gray Wolf barrels spent roughly half their time aging in Kentucky, and the other half in Texas. 

“The climatic whipsaw over the last three years in Hill Country with some of the coldest cold we’ve ever experienced, along with extreme drought and long periods of intense 100+ degree heat had a tremendous effect on the rate of maturation and the final flavors that you just won’t get in other locations.”

The first release in the 2025 Milam & Greene Wildlife Collection is named for the largest species of the wolf family, which historically hunted the lands where the distillery is now located in Blanco, Texas. Gray Wolf pups are born in Spring, just like this release.

The Wildlife Collection: Gray Wolf Single Barrel Bourbon

This limited cask-strength Milam & Greene Wildlife Collection Gray Wolf Straight Bourbon was distilled at the Green River Distilling Company, in Kentucky, with a mash bill of 60% corn, 36% rye, and 4% malted barley. It was barreled on May 18, 2018, and aged in Owensboro, Kentucky for three years, eight months, and 25 days before being transported to Blanco, Texas, and aged for an additional three years and one month on the north side of Milam & Greene Rickhouse 2. Gray Wolf Straight Bourbon was bottled on March 14, 2025, and has plenty of bite at 125.5 proof (62.75% ABV) after aging for a total of six years, nine months, and 25 days.
