Along with Tom Lubbe of Matassa and Gérard Gauby of Domaine Gauby, Thomas Teibert is one of the handful of dedicated (perhaps fanatic) vignerons committed to working the rugged terroir of Calce. The shallow topsoils here are generally no deeper than one foot, so the vines plunge almost immediately into the mother rock of brown and black slate, with occasional breaks into marl and gravel. Buffeted constantly by wind and chilled by its high altitude, Teibert’s vines yield wines of striking minerality and clarity. The cool climate here ensures brilliant acidity and wines that rarely exceed 13% ABV.
