Eagle Rare 10 Year Kentucky Straight Bourbon Whiskey. Masterfully crafted and aged in oak barrels for no less than 10 years, Eagle Rare boasts a complex array of flavors, offering a distinct taste experience. As soon as you pour a glass, you're enveloped with aromas of toffee, honey, leather, oak, herbs and orange peel. Take a sip and you'll get that oaky flavor complete with cocoa and almonds. It sounds like a delicious breakfast cereal, but it's better sipped in the evening with friends after a long day at the office.
