A high vacuum pump removes approximately 90% of the air from the bottle, after which the bottle is filled with an inert gas. Normally nitrogen is used, but CO2 or a mixture of nitrogen and CO2 can also be used.
Air suction and neutral gas injection only take place if a bottle is present.
Thanks to our special (patented) filling valves, the same atmosphere is created in the filler bowl as in the bottle.
De-aeration reduces average oxygen absorption on filling from an average of 0.6 to 0.09 mg per liter of wine, and the amount of oxygen contained in the head space is reduced from 0.1 to 0.08 mg.
