The vines in spring

The vines begin to "weep". The sap starts to rise and oozes out of the winter-pruned cane-ends. Shoots that have been cut are gathered up to be burnt. It's also the time for vine training, where the two canes are arched over and secured to the wires. The sun comes out, the soil begins to get warmer and the conditions are good for planting young vines, which will only produce fruit after four or five years.

The vines stop weeping after two to four weeks, at bud-break, when the buds start opening. The vines start to grow come April/May. In good weather conditions, shoots can grow up to 5 cm per day.
The next job for the winemaker is disbudding, where unwanted suckers on the lower part of the vines are removed to concentrate the energy in the upper part of the plants.

In June, training begins, whereby the growing stems are secured to the trellises to prevent them breaking and getting tangled up and also to leave enough space for spraying and other treatment. Once each shoot has 15 to 16 flowers, it is ready for flowering (mid-June).
During this period, the weather is crucial for the future of the vintage and the temperature must not go below 15°C, otherwise flowering will stop. Muscat and Gewurztraminer are the most sensitive varietals.

The best time for flowering is between 11 and 24 June, St. John the Baptist's day. A hundred days later, the grapes should be ripe and ready for picking!
