Eagle Rare 10 Year Old has long been a beloved expression under Buffalo Trace‘s portfolio.
The brand was first introduced in 1975 by Charles L. Beam, the grandnephew of Jim Beam. In 1989, the brand was purchased by Sazerac and, since 1992, the bourbon has been produced at Buffalo Trace Distillery.
One of the enduring mysteries of Eagle Rare 10 Year Old is the mash bill. We know that the bourbon is produced using Buffalo Trace’s mash bill #1, the same as some other brands such as George T. Stagg and Col. E.H. Taylor Jr. Of course, the mash bill is at least 51% corn (otherwise Eagle Rare 10 could not be classed as ‘bourbon’), but the rest is a mystery. There is a general acceptance that there is less than 10% rye in the mash bill, but the exact quantity is not known.
The whiskey is matured for at least 10 years in “alligator barrels”. These barrels are charred for a minimum of one minute, leaving deep and charred ridges in the wood. The ridges encourage more interaction between whiskey and wood, giving Eagle Rare a rich and complex profile.
Despite its relative affordability in comparison to other luxury bourbons, Eagle Rare 10 Year Old remains difficult to get a hold of in the USA. This is due to limited release numbers, and allocations to specific bars, retailers, and restaurants.
