The harvests are carried out by hand, as each plot reaches perfect ripeness. The grapes undergo an initial sorting in the vineyard, carried out by the pickers.
Two further sorting stages take place in the vat room, before and after removal of the stalks, to optimize the quality of the fruit.
Alcoholic fermentation takes place in small concrete vats, separated by grape variety and plot, the juice and skins are then left to macerate for two to three weeks.
The free-run wine is then drawn off and kept separate from the wine obtained by pressing the residue ("marc"). The second fermentation, or malolactic fermentation, is then carried out, each grape variety being kept separate, either in barrels or vats, depending on the quality of the batches.
The wines are then transferred to oak barrels (50% new barrels).
They mature for eighteen months, during which the wines are progressively blended during meticulous rackings approximately every three months.
The contact with the fine lees and the oak tannins gradually adds structure and complexity, enabling the production of wines that can be laid down and that will improve over time.
The estate can produce up to 100,000 bottles.
A second wine, an AOP Pomerol, l'Hospitalet de Gazin, was created in 1986 so that Château GAZIN could be made with only the best grapes from each harvest.
After being bottled and placed in wooden cases on the property, the wine is distributed all over the world by wine merchants in Bordeaux. 86% of Château GAZIN's production is sold to wine lovers outside of France.
