Eagle Rare bourbon 90 proof. Rare was originally a 101-proof ten-year old Kentucky Eagle Rare was among the last new bourbon brands introduced prior to the current era of 'small-batch bourbons'. The Sazerac Company, an American family owned producer and importer based in New Orleans Buffalo Trace Distillery. 6/7/14 having my first sip at the Peabody in Memphis. It is charred oak barrel with a sweet taste and a little burn the first sip then mellows out.
