Matin Calme is able to grow fully mature grapes of high acidity and great density without developing wines of high alcohol. The viticulture is Ecocert certified organic and the soils are tilled by hand. The fruit is manually harvested and gently pressed in a vertical press. The wine is never pumped and the fermentation is completed with only the natural yeasts. There is no SO2 used in the fermentation process and in certain vintages, like the 2008, there is no SO2 used at all. The yield is very, very small at 20 hl/ha and there is no fining or filtration whatsoever...Terroir at its purest.
