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.

Bloom

May

May marks a critical phase in the vineyard. Tissue sampling, like Petiole Analysis, is conducted to understand nutrient levels, crucial for the vines' optimal growth during this delicate flowering period.

Focus shifts to fruit set, where the flowers transform into tiny grape berries. Practices like leaf removal are implemented to improve sun exposure and air circulation around the young clusters, vital for healthy development.

Mid-Season

June–July

As summer progresses, vineyard managers estimate crop yield and engage in veraison thinning – selectively removing some grape clusters to enhance the quality and even ripening of the remaining fruit.

Pre-Harvest

August

In the lead-up to the harvest, fruit sampling becomes paramount. Tests for pH, titratable acidity (TA), and Brix (sugar content) are crucial in determining the perfect timing for harvest.

Harvest

August–September

This is the zenith of the viticultural calendar. The precise timing of the harvest is a critical decision, directly impacting the flavor profile and quality of the wine.
