Dormant Season

December–February

During the colder months, the vineyard may seem quiet, but vital work is underway. Pruning is the main task - a strategic shaping of the vines to set the stage for the next season's growth. This careful trimming is essential for controlling both the yield and quality of the forthcoming harvest.

Pre-bloom

March–April

With the arrival of spring, the vines awaken. Shoot thinning and positioning become key to managing the vine's energy, ensuring adequate sunlight and air circulation for healthy growth. This period also sees nitrogen fertilization to support the vines' vitality.
