Harvesting in Champagne is an entirely manual process, selecting whole, undamaged clusters that must remain that way right up to the point of pressing. This is essential to avoid staining the musts, bearing in mind that 70% of Champagne wines are made from black grapes.
The actual start of picking varies with each producer but cannot commence before the date fixed by the Comité Champagne on the basis of reference values established for each vine parcel and grape variety, using the hundreds of thousands of samples collected by the"Réseau Matu"(Ripening Observation Network).
