Geological time
The terroir of this place is placed under the dependence of geological formations of lacustrine origin, of Oligocene age (- 35 to - 25 Ma).
The Beauregard bar consists of sandstone limestones from the base of the Miocene (-24 Ma) which, during the cold phases of the Quaternary, nourished its slopes with fragments and fragments which formed a vast sheet of colluviated scree.
Geographic location
Isolated at the edge of the commune between the Rieu and the Beauregard ridge, there is a valley very sheltered from the fury of the mistral. It is a microcosm within the Vacqueyras space, located near Gigondas.
In the direction of Petit Montmirail, the presence of a limestone bar limits the gaze to the east. Very wooded, rocky, it has a piedmont made up of scree packed in more or less marly materials.
Weather
In a valley where the mistral gives up dominating the sun, a confidential vineyard has developed, a sort of garden that the vine explores to give charming and fruity wines. The small Oligocene valley enjoys a very sheltered situation; it benefits from the shadows provided by the Dentelles massif to the east and the Beauregard bar to the west.
Soils
It is the red, salmon or orange-colored marls, as well as clay sands and thin cobbles, which form the foundation of this valley.
The Beauregard bar is made of sandstone limestones, very straightened by the tectonics of
Montmirail lace.
On the east side, this bar passes to light-colored clay limestones.
Grape varieties
Grenache finds in the Oligocene marls one of its most beautiful expressions.
Syrah is present there, but in a secondary manner.
Rich, complex, fleshy, all the attractive characteristics of Grenache are found in the red wines obtained on these terroirs.
White grape varieties can be installed, but their place is less assertive.
For the Piedmont of Beauregard, the wines are marked by a dense and lively tannic structure. The red grape varieties give wines whose aromas are associated with those of acid red fruits; redcurrant, raspberry, strawberry, while minerality is present in white grape varieties.
