Our wine
Stainless-steel cuvée, oak-barrel cuvée and fermentation control.
For each vintage and each appellation, if the harvested quantity is sufficient, we make both a stainless-steel cuvée and an oak-barrel cuvée. For the oak-barrel cuvée, one quarter of the barrels are new so that the wine is not overly oaky.
Since 2017, stainless-steel coils have helped regulate the wine temperature during fermentation. Yeasts consume sugar and turn it into alcohol, releasing heat and carbon dioxide: about 17 g of sugar are needed to produce 1% alcohol by volume. At 14% vol, the yeasts have consumed 238 g of sugar per litre.
This heat must be dissipated: without regulation, the vat can rise above 30°C and stop fermentation. Once the sugars are consumed, fermentation is over; the vat is then warmed to around 27 to 28°C for maceration lasting about 15 days to 3 weeks, before running off, pressing, bottling and tasting.
The Fronsac is mostly Merlot with Cabernet Franc. The estate’s Canon Fronsac is 100% Merlot.
