Accurate vinification

The vinification process must bring out but also preserve the very delicate aromas of the Chardonnay grape. For must purchases, the winemaker is present for each pressing on the winegrower’s own premises, in order to best estimate pressing time and vinification for each cuvée.

“Vinification for whites requires great care and a lot of sensitivity. Wine is a living product and in the early stages, it is extremely fragile. My aim as enologist in a region like Chablis is to preserve as much as possible of the aromatic potential in the grape to bring out the expression and characteristics of the terroir after vinification. The most important thing for me is to let the grape express the maximum possible in the finished wine. It was on this principle that J. Moreau & Fils established its approach to winemaking.

“Everything is done to avoid oxidization and to preserve the characteristic aromas of a Chablis wine. The grapes are pressed in a pneumatic press over a long, gentle cycle so as not to extract any bitter elements. The musts are protected following pressing and are left to settle for a night using a static process. They are then quickly inoculated with yeasts selected for their aromatic neutrality, or else using natural yeasts taken straight from the best quality plots in tip-top condition.

“Once the alcoholic fermentations are completed, we want to trigger the malolactic fermentations – a process which converts malic acid to lactic – as soon as possible to avoid periods when the wine is just sitting there, when it is vulnerable to premature oxidization". 

“Upon completion of these stages, the wines are sulfured to protect them and remain on the lees for ageing which further protects the wine and gives it roundness and complexity. Chablis is aged for between six and eight months for the village wines, and from 10-14 months for the premier and grand crus, adjusted according to the vintage".

“Certain premier or grand cru wines are partially fermented and aged in barrels, but only ever a fraction of the finished wine will have been in oak because Chablis is all about freshness. The choice of barrels is crucial for wines as sensitive as Chablis and we favor very fine-grained wood and a medium toast with the aim of enhancing the terroir and not masking it with aromas of oak. This is the best way to reveal its complexity".

Wines are inoculated with natural yeasts taken straight from the best quality plots, selected by the winemaker which received little or no treatment and which were in good health. The grapes are then pressed and the must from each pressing is fermented separately for a week open to the air to obtain a juice that is rich in indigenous yeasts, called levain – a sort of starter culture – which is then poured directly into certain cuvées in fermentation.
