Diageo’s Orphan Barrel line of rare whiskies created with the goal of sharing lost barrels with discerning consumers, has added Rhetoric 22-Year-Old bourbon. Aged one year longer than last year’s Rhetoric 21-year-old, this release (the eighth orphan barrel overall) is slightly more mature. remaining barrels of rhetoric will continue to be aged and re-released annually, allowing aficionados to collect the series and compane the different ages side by side. Rhetoric 22-Year-Old bourbon Mash: 86% corn, 8% barley, 6% rye; 90.4 proof.
