Eagle Rare 10yr--along with the Buffalo Trace Bourbon--is one of Buffalo Trace's flagship spirits. Along with the required 50%+ corn in the mash bill to qualify as a bourbon, Eagle Rare has a somewhat higher quantity of rye, giving the bourbon a spicier, more robust flavor. As the label suggests, it's aged for 10 years on site.

In 2014, Eagle Rare dropped the "single barrel" designation and took the "10yr" out of the title and moved it to the label description. We verified with Buffalo Trace that the bourbon remains a full 10 years aged and "the company has absolutely no intention of dropping [the 10yr label], and it has plans on the books to keep it at 10 years through 2047." Despite some tumult among customers, they claim there is no formula change.

One doesn't often think of buffalo in Kentucky but the distillery takes its name from the buffalo path (or "trace") that led to the banks of the Kentucky River in Franklin County. Buffalo Trace Distillery takes pride in the limestone water (being notably free of iron) and good soil conditions for grain. The site has had a working distillery since 1787 but the official Buffalo Trace first began operation in 1857. It obtained one of only four permits offered during Prohibition to maintain production for "medicinal purposes." Today, the distillery sits on a picturesque 119 acres and produces several labels of bourbon. Buffalo Trace was named Distillery of the Year by the 2008 San Francisco World Spirits Competition. It was named a national historic landmark in 2013.
