The Cabernet Sauvignon is hand-picked at about 10° alcohol. The free run juice (saignée) is sent to an airtight stainless steel tank where it ferments on it own with nothing added to it -- no dosage, no liquor, no gas, no sugar, no yeast. This single fermentation is referred to as Method Charmat. While similar to Petillant Natural, the difference is that the fermentation does not take place in bottle.
