Pruning is really important
Since the begining of the year, we do the pruning in our vines in order to prepare the new life-cycle of our vine stocks. The pruning in Champagne begin just after the leaf-fall.
There are four approved pruning methods: Chablis system, Guyot system, Vallée de la Marne system, Cordon system. In the Champagne Julien Chopin, we use the Chablis system.
The first purpose of pruning is to encourage the sap to flow toward the fruit-bearing buds. The buds require an even distribution of sap for vigorous growth but excess sap may compromise productivity. Ideally, there should be a good balance of vigour and productivity – two conflicting requirements that are not easily reconciled.
