Wine destined to become Blanquette méthode Ancestrale undergoes its primary fermentation in concrete tanks, unlike their more modern counterparts Blanquette or Crémant de Limoux which are vinified in...

...stainless steel tanks. As with Champagne, the primary fermentation is relatively short and high temperature with no malolactic fermentation. More flavor development takes place during secondary fermentation in the bottle.

I couldn't help thinking that this huge fermentation warehouse would make a great set for a video game.

Analysis
Analysis
Wine making is serious business and at Sieur D'Arques, bottles are carefully analyzed to determine the ratios of various fermentation by-products. The method is constantly being fine-tuned by the winemakers to push their products towards a more desirable end result.

The spent yeast is traditionally removed by rapidly opening the bottle upside down, allowing just the lees to pop out, then quickly re-capping it. These days, this disgorgement is done by machine. Here a giant robotic arm picks up bottles 100 at a time and dips their tops into a liquid nitrogen solution, creating a frozen ice plug right at the stopper.

The sugar and wine added during dosage needs to be well-mixed. This machine rotates the bottles a few times to ensure a thorough homogenization.
