Viticulture refers to the cultivation of grapevines, primarily for the production of wine, but also for raisin and table grape consumption. It is a branch of arboriculture, which is the cultivation of trees. The practice involves a deep understanding of grape varietals, soil types, climate conditions, and vineyard management techniques.

The selection of grape varietals is crucial, as different types of grapes thrive in specific environments and yield distinct flavor profiles. Key environmental factors include climate, with temperature, rainfall, and sunlight playing vital roles in grape ripening and sugar development. Soil composition also significantly impacts the vine's growth and the resulting wine's characteristics, often referred to as terroir.

Vineyard management encompasses a range of practices aimed at optimizing grape quality and yield. This includes pruning, which controls vine growth and fruit production, trellising, which supports the vines and improves air circulation, and canopy management, which manipulates leaf cover for optimal sunlight exposure and disease prevention. Pest and disease control are also integral to viticulture, protecting the vines from various threats.

The timing of harvest is critical, as grapes reach their peak ripeness at a specific window. This ripeness is determined by factors such as sugar levels, acidity, and phenolic maturity. Once harvested, the grapes are typically transported to a winery for vinification, the process of winemaking. Viticulture, therefore, forms the foundational step in the creation of wine, dictating much of its final quality and character.
