The Cave in Vinsobres is a cooperative enterprise. Vinsobres is located at the top of a small mountain and provides south-facing slopes at higher altitudes that allow production of high-quality grapes. Because of this terrain and its reputation for quality, Vinsobres is the first village in the Drome to receive a Cru designation for its wines. This is the highest designation available for villages and requires the producers to restrict the numbers of acres of production to maintain quality. While wines from Vinsobres are available throughout Europe, the Cave's wines have never been exported to the U.S.
The Emeraude is one of the Cru wines. It is made from grapes from vines at least 40 years old and is restricted to years of better growing conditions. It is also aged for 12 months in wood and so has slight vanilla undertones. 2007 was an excellent year for wine grapes in Vinsobres, and the 2007 Emeraude has more deep ripe fruit flavor than the 2005, as well as a little more spice.
