The terroirs are highly diverse, with Grenache primarily sourced from the north and central areas of the Vaucluse department, while Syrah comes from the northern part of the Gard department.
The soils and microclimates from which this wine originates vary significantly, with each plot planted with the grape variety best suited to its conditions. Grenache, which makes up about 60% of the blend, thrives on hillsides with good southeast exposure and is planted in sandy-clay, clay-limestone and silty clay soils often covered with pebbles or gravel, as well as deep red clay. Pebbly soils impart concentration, clay-limestone adds power and depth, while sandy soils bring finesse to the blend.
Syrah (around 30%) grows mainly on clay and sand at the foot of the slopes, contributing to a balance of freshness and finesse. Depending on the vintage, the blend may also include up to 10% of complementary grape varieties such as Mourvèdre, Cinsault, and Counoise.
Fiole Réserve is classified as a Côtes du Rhône Villages, though its quality is on par with that of a Côtes du Rhône Villages with village name. However, since it is made from grapes sourced from several villages, such as Laudun, Valréas, Rochegude, Vinsobres, and Cairanne, it cannot be classified within this specific AOC segment.
