Harvesting & wine-making

The choice of the date of harvest is decisive to obtain a perfect maturity. Actually, the oceanic climate compels wine-growers to know perfectly the maturing process for each plot of vines and to master grapes preservation. The follow-up of every plot is essential to determine the date of harvest. To build its diversified range of Muscadets, Famille LIEUBEAU constitutes homogenous wine-making lots based on the qualities of each property. The vats contain between 5,000 and 30,000 liters, and can receive the grape juice from plots of less than one hectare to five or six hectares ones.

Mechanical harvest techniques enable to harvest grapes at full maturity. They are sorted out directly by the mechanical grape harvester. Right after that, the grapes are brought to the cellar; then, depending on the wine they will be used for, they either receive skin maceration or are directly pressed in a pneumatic press. Cold soaking, clarification and alcoholic fermentation are the next steps of the process.

A part of the grapes is still manually harvested; this is namely the case of old vines plots used for special wines such as Folie Nantaise, M de la Fruitière or Sensuel.

Vinification on lees is a specific ageing process used in the vineyard of Nantes. This technique consists in letting the wine relying on its lees until bottling. Lees are made of dead yeasts as well as natural elements from the grapes and their fermentation. All these elements settle slowly at the bottom of the tank or the barrel during the winter. The wine remains this way, without racking, until bottling. It keeps its freshness, develops complex aromas and is ready for keeping.

Famille LIEUBEAU is a specialist of dry white wines production. Both traditional and innovative methods are used in the wine-making, ageing and bottling steps of the production.
