Champguyon is a small rural commune of 298 inhabitants in the west of the Marne département, close to Sézanne and Esternay. It is not a wine village with a cru classification, but it makes a quiet base for exploring the area.
Location
Champguyon lies in the west of the Marne département, around 85 kilometres east of central Paris. Administratively, the commune belongs to the arrondissement of Épernay and the canton of Sézanne-Brie et Champagne. Its neighbours include Morsains, Les Essarts-lès-Sézanne, La Noue, Esternay, Neuvy, Joiselle and Tréfols.
With 298 inhabitants (2023), Champguyon is small. That figure is about 8.8 per cent higher than in 2017. The statistics classify it as a rural commune with scattered housing. It lies outside any major urban area and falls within the catchment area of Montmirail.

Landscape and climate
The commune is drained by the Ruisseau de Vessard and the Ruisseau de la Fontaine Bouillante, both of which belong to the Seine basin. In terms of water management, the village falls under the plan for the Petit Morin and Grand Morin.
The climate is temperate oceanic, with cool summers and cold winters. The nearest Météo-France weather station is in Esternay, only five kilometres away. For 1991 to 2020 it records:

Growers in the region know such swings from first-hand experience, since heat and frost shape every vintage.
Name and sights
The place name is recorded as far back as 1161 in the Latin form Campus Guidonis, which can be read as "Guido's field". Later spellings include Champ-Guion, Champguion and Changuyon. The Changuion family also originates from Champguyon.
As its one sight, the source names the church of L'Invention-de-Saint-Étienne. Beyond a visit to the village church and a walk through the countryside, there is not much else to expect here. If you are after peace and quiet, you will find it.

Champguyon holds neither grand cru nor premier cru status. Whether, and to what extent, vines grow here is not clear from the information available. We would therefore rather not credit the village with a winegrowing tradition it may not have.
It is still of interest to travellers. Sézanne, whose surrounding area counts among the champagne growing districts, and Esternay both lie nearby. If you want to explore the western reaches of the region, Champguyon makes a quiet stop along the way. A glass of champagne is then best enjoyed at a tasting with a grower in the surrounding area.
