Anyone who knows Paul Grieco will tell you that he is patently insane. Final proof, if any were needed, lies in this video promoting his new wine bar, Terroir. Grieco, the co-owner, manager, and wine director of both Hearth and Insieme, is the mad genius of the city’s wine corps, and Terroir is his padded cell and laboratory. The teaser site gives some hint of the white-knuckle wine-geek intensity that courses through Grieco’s veins: Among the vitriolic mottos that flash are “Our wine world is now dominated by over-manipulated, oak-chip-flavored, micro-oxygenated wines that have nothing to do with what Mother Nature, God, or the Cistercian Fathers had in mind” and “To go to Friuli for red wine is like going to Las Vegas and expecting to catch Arthur Miller’s The Crucible.” But to really get a measure of his madness, watch this video. You won’t be sorry.
