Belargus owns a tiny plot (0.35ha) of Chaume 1er Cru that surround sthe place called "L’Echarderie", which used to be, until the French revolution, the cellar of the lords of Haute-Guerche (who were farming the Chaume vineyards on behalf of the Ronceray Abbey).

The marriage of schist and puddingstone in the soils gives this cuvée a mineral complexity and a slight bitterness on the palate. It is is a sweet wine fermented and aged in oak barrels. The result is a wine with a complex structure, showing aromas of caramel and mocha. The sweet mouth lengthens on a marked bitterness, typical of the soils of Chaume. The 2018 vintage was historic, in Anjou as in many French regions, with good yields and exceptional grape quality. The winter had started early and was quite cold, with severe frosts. The land was thus opened, allowing nitrogen fertilization as well as soil oxygenation. Generous rains helped building a comfortable water reserve. The hot and humid spring allowed the vines to grow well, but also brought strong mildew pressure, especially in June. The summer was particularly hot and dry, but the vines did not suffer thanks to the sufficient accumulated reserves. The dry wines harvest began on September 10th and went on for twenty days without a single drop of rain, perfect conditions which allowed optimal management of the ripeness.
