The appellation, named after the village of the same name (Côtes de Fronsac until 1976) is located in the Bordeaux region to the west of Saint-Émilion and Pomerol. Until well into the 19th century, the wines from Fronsac were more important than those from the now dominant neighbour Pomerol. The vineyards cover some 1,000 hectares of vineyards in the communes of Fronsac, La Rivière, Saint-Germain-de-la-Rivière, Saint-Michel-de-Fronsac, Saint-Aignan, Saillans and parts of Galgon. Parts of the two communes of Fronsac and Saint-Michel-de-Fronsac with special soil have the right to the name Canon-Fronsac (or Côtes de Canon-Fronsac).
The tannin-rich and long-lasting red wine is blended from the grape varieties Merlot (main variety with at least 85% in most cases), Cabernet Franc, Cabernet Sauvignon and Malbec(Cot). These are the typical grape varieties of the Rive droite (right bank). As in the Pomerol area, there is no Grand Cru classification. Well-known vineyards are Château Canon, Château Canon de Brem, Château Canon Moueix, Château Dalem, Château de Carles, Château Fontenil, Château de la Dauphine, Château La Grave, Château la Rivière, Château La Vieille Cure, Château La Villars, Château Mayne-Vieil, Château Moulin-Haut-Laroque and Château Villars.
