The great diversity of soils and climates on the Cote du Rhone has led to several grape varieties, including the Grenache and the Syrah, being grown here. The Grenache red grape variety endows the Maison Castel Cote du Rhone wine with fruit, warmth and smoothness, while the Syrah confers spicy aromas, colour and a firmer structure. Slow, traditional vinification is carried out to retain the character of the terroir and the grape variety. Blending is carried out with precision applying the typically French expertise with Cotes du Rhone wines.
