Chouilly (postcode 51530) is a small commune in France, in the Champagne Côte des Blancs region. The commune has 1,013 inhabitants (as of 2016). Chouilly is located about 4 km east of Épernay. In 1985, with the reclassification, in Champagne, Chouilly was upgraded and since then carries the status of Champagne classification, as a Grand Cru place. However, the Grand Cru status is limited to the white grapes. The black grapes are still in the rank of Premier Cru, but have been raised from 90 to 95%. Only a few vineyards are located adjacent to the village. They are on rather flat terrain, some towards Épernay, bordering on the suburbs. Most of the vineyards are located south of Chouilly, on the northern side, on the slopes of the Butte de Saran and its foothills towards the north. In addition, there are a few vineyards on the eastern slopes of the Butte de Saran. In between lies the Château de Saran.

The vineyards adjacent to the village and those towards Épernay, are rather average quality. The vineyards on the slopes of the Butte de Saran and running out, are at an altitude of 100 to 120 m, are of very good quality. The best sites are on the southeast side, up to an altitude of 220m. There, however, the border with Cramant runs, so that most of the outstanding sites belong to Cramant. The commune has about 525.5 hectares (as of 2019) of vineyards. As usual in the Côte des Blancs, the vineyards are almost exclusively planted with the Chardonnay grape variety. The Chardonnay vine accounts for 519 hectares. 5 hectares are cultivated with Pinot Noir and only 1.5 hectares with Pinot Meunier.
