Last week Domaine Wine Shippers lined up the big guns of Domaine Raveneau and Domaine Laroche with the new guy, Patrick Piuze, from precocious Petit Chablis to profound Grand Cru Les Clos. After an hour of intensive interrogation, Raveneau claimed three of my top five wines and Piuze snared two. Terroir de Courgis is a Chablis subregional blend, and one of the best value introductions to the charms of this region at the moment. Generous fruit presence of white peach and glace fig is honed with grapefruit juice and lemon zest, built around Chablis’ defining structure of ultra-fine, chalky minerality.
