Château Sainte Marguerite is a winery based in Provence's Côtes de Provence appellation, in southeastern France. The estate focuses exclusively on rosé production, a natural fit for a region where rosé represents the majority of annual output and has been refined over centuries of winemaking tradition.

Côtes de Provence rosés are characterised by their pale salmon colour, delicate fruit profiles, and dry finish. The appellation's Mediterranean climate—with warm days, cool nights from marine influences, and well-drained limestone soils—creates conditions suited to producing dry, refreshing wines rather than sweet or heavy styles. This balance of freshness and subtle flavour complexity distinguishes the region's best examples from simpler holiday wines.

The estate's current range employs the classic Provençal blend of Grenache, Cinsault, and Rolle, the three varieties that form the backbone of quality Côtes de Provence rosés. Cinsault provides acidity and delicate red fruit notes, Grenache contributes structure and warmth, while Rolle (also known as Vermentino) adds aromatic complexity and minerality. The two expressions currently available—Fantastique and Symphonie—reflect different approaches to this traditional combination.

Provence spans southeastern France along the Mediterranean coast, stretching from the Italian border west to the Rhône delta. This ancient wine region produces approximately 170 million bottles annually, with rosé wines comprising roughly 90% of total production. The region encompasses eight appellations, including Côtes de Provence, Bandol, and Cassis, distributed across varied landscapes from coastal plains to limestone hills and mountainous terrain.

The Mediterranean climate provides abundant sunshine, warm temperatures, and the cooling influence of the mistral wind, which helps maintain acidity and reduces disease pressure in the vineyards. Soils vary significantly across the region, from limestone and clay in the hills to sandy coastal areas and schist in certain zones. Côtes de Provence represents the largest appellation, while Bandol focuses on structured reds from Mourvèdre, and Cassis specializes in distinctive white wines from local varieties.

Traditional grape varieties dominate plantings, with Grenache, Cinsault, and Syrah forming the backbone of most rosé blends, often complemented by Mourvèdre and Tibouren. White wines typically feature Rolle (Vermentino), Clairette, and Ugni Blanc, while reds emphasize Grenache, Syrah, and Mourvèdre. Provençal rosés are characterized by their pale salmon color, achieved through minimal skin contact and immediate pressing, resulting in fresh, dry wines with delicate fruit flavors and mineral notes that reflect the region's diverse terroir.

Côtes de Provence is an appellation located in southeastern France within the Provence region, stretching across the departments of Var and Bouches-du-Rhône. The appellation covers a substantial area of Mediterranean coastline and inland terrain, encompassing zones from the Maures Massif to the Esterel mountains. The appellation was officially established in 1977, recognizing the region's long winemaking tradition dating back centuries.

The appellation benefits from a Mediterranean climate with warm, dry summers and mild winters, moderated by the Mistral wind. Soils vary across the region, ranging from limestone and clay to schist and sandstone, contributing to diverse microclimates within the appellation. Côtes de Provence permits a broad range of grape varieties: Grenache, Cinsault, Syrah, and Mourvèdre dominate red and rosé production, while whites may include Rolle, Semillon, Ugni Blanc, and Sauvignon Blanc. The appellation is not restricted to single-varietal wines; blended wines are standard practice across all three colors.

Rosé wines are the hallmark of Côtes de Provence, typically produced in a dry style with pale salmon coloring. These rosés offer delicate red fruit aromatics and refreshing acidity, suited to the region's warm climate. The appellation also produces dry white wines with citrus and mineral notes, and red wines ranging from light and fruity to more structured examples, depending on the specific blend and producer. The diversity of the appellation reflects both its geographic range and the flexibility winemakers have in blending across permitted varieties.
