Soil : The hill-slope of Corgoloin are carved into the hard limestones of the upper bathonien. The slopes are gentle and regular, not reaching the rim of the plateau. In the upper part the brown soil is only slightly limy, lower down, a thick layer of pebbly scree, while at the foot of the slope it is an extensive area of brown soils over accumulated alluvium.
Maceration process : 0% whole bunch. five days of cold maceration, one "pigeage" a day at the start of the alcoholic fermentation, then pump-overs during maceration for a gentle extraction
