Cornas is a small wine appellation located in the northern Rhône region of France. The name "Cornas" is derived from the Celtic word for "burnt earth," which is a reference to the steep, rocky slopes that characterize the vineyards in this area. The appellation covers just over 100 hectares of land, and is known for producing some of the most powerful and complex red wines in the Rhône Valley.

The style of production in Cornas is heavily influenced by the unique terroir of the region. The vineyards are situated on steep slopes that face south or southeast, which allows the grapes to receive maximum exposure to the sun. The soil in Cornas is composed of decomposed granite, which is rich in minerals and provides excellent drainage for the vines. The combination of these factors results in wines that are full-bodied, rich, and complex, with intense aromas and flavors.

The primary grape variety grown in Cornas is Syrah, which is known for its deep color, intense aromas, and full-bodied flavor. The Syrah grapes grown in Cornas are typically smaller and more concentrated than those grown in other regions, which contributes to the intensity and complexity of the wines. In addition to Syrah, some producers in Cornas also grow small amounts of white grapes, such as Marsanne and Roussanne, which are used to produce a small amount of white wine.

The typical wines produced in Cornas are full-bodied, rich, and complex, with intense aromas of black fruit, spice, and earth. The tannins in these wines are firm and well-structured, which allows them to age gracefully for many years. The best examples of Cornas can be quite expensive, but they are considered to be some of the finest wines in the Rhône Valley.

The history of winemaking in Cornas dates back to the Roman era, when the region was known for producing high-quality wines. However, it wasn't until the 19th century that Cornas began to gain recognition as a distinct wine appellation. In the early 20th century, the vineyards in Cornas were devastated by phylloxera, a disease that nearly wiped out the entire wine industry in France. However, the vineyards were eventually replanted, and today Cornas is once again recognized as one of the premier wine appellations in the Rhône Valley.
