Spontaneously, when one thinks of winemaker's cellar one imagines vaulted cellars, rows of barrels, trembling lights and a constant temperature whatever the season. This is true in some limestone vineyards where it is possible to dig the basement. The vineyard of muscadet is established on subsoils of granite, gneiss, gabbro, plutonic rocks dense and almost flush. How to dig ? Therefore, traditionally, the winegrowers raised their wine in wooden containers (barrels, fowls) in stone buildings. Then in the years 30-40 were built the first concrete tanks covered with glass tiles. First aerial then, when the ground allowed it, underground. The glass tile coating allows the tank to be perfectly sealed, totally neutral, protected from oxygen. The parallelepiped shape is ideal for the contact of the wine with the lees. The underground tank adds a criterion of thermal inertia very useful for the prolonged aging (2, 3 or even 4 years) of our crus.
Inside the vat, everything is smooth, the wine takes golden shades (picture taken during a bottling, the tank is normally full), the sound resounds. Magic.
Then of course we also use stainless steel tanks for short elevages, barrels for the cuvée granite in red and 2 ovoid tanks. But this is another story !
