[fs-toc-h3]Geographical and climatic factors for wine production

• Alluvial soil: Soil is composed of river deposits, often ideal for grape growing.
• Altitude: Elevation above sea level, affecting temperature and sunlight exposure.
• Continental climate: A climate characterized by distinct seasons with hot summers and cold winters, found in regions like Bordeaux.
• Diurnal temperature variation: The difference between daytime and nighttime temperatures, influencing grape ripening and flavor development.
• Granite soils: Volcanic or igneous soils rich in minerals, often found in wine regions like the Northern Rhône.
• Humidity: The air's moisture level, impacts disease pressure and grape development.
• Limestone soil: Soil rich in calcium carbonate, contributing to mineral complexity in wines, common in Champagne and Burgundy.
• Mediterranean climate: A climate with hot, dry summers and mild, wet winters, typical in regions like Tuscany and Napa Valley.
• Microclimate: Small-scale climate variations within a larger region, affecting grape growing conditions.
• Ocean influence: Proximity to oceans can moderate temperatures and provide cooling breezes, as seen in regions like Sonoma Coast.
• Rain shadow effect: Dry regions created on the leeward side of mountain ranges due to moisture being blocked, impacting rainfall.
• Slope and aspect: The angle and orientation of vineyard slopes influence sunlight exposure and drainage.
• Soil composition: The mixture of minerals, organic matter, and texture in the soil, affecting vine health and wine character.
• Terroir: The unique combination of soil, climate, and geography in a vineyard, influencing a wine's character.
• Volcanic soils: Soils enriched with volcanic minerals, found in regions like Mount Etna in Sicily.

[fs-toc-h3]Viticulture practices

• Canopy management: Techniques used to control the growth of grapevines' foliage, optimizing sunlight exposure and airflow.
• Cover crops: Plants grown between vine rows to improve soil health, prevent erosion, and provide habitat for beneficial organisms.
• Crop thinning: The removal of excess grape clusters to improve grape quality and concentrate flavors.
• Dry farming: Growing grapevines without irrigation, relying solely on natural rainfall, promoting deep root growth.
• Green harvest: The early removal of grape clusters to reduce vineyard yields and enhance grape quality.
• Integrated Pest Management (IPM): Sustainable pest control practices that minimize chemical intervention, utilizing natural predators and monitoring.
• Irrigation: The controlled application of water to grapevines, essential in arid regions to maintain vine health and grape quality.
• Leaf pulling: The removal of grapevine leaves to increase sunlight exposure to grape clusters, aiding ripening and disease prevention.
• Organic viticulture: Farming practices that avoid synthetic chemicals and promote biodiversity, using organic fertilizers and natural pest control methods.
• Pruning: The annual trimming of grapevine canes and shoots to manage growth and control fruit production.
• Rootstock: A vine's root system, often grafted with a scion to influence vine characteristics and disease resistance.
• Sustainable viticulture: Holistic vineyard management practices that consider environmental, social, and economic factors to minimize environmental impact.
• Trellising: A system of wires and posts used to support grapevines, control canopy growth, and improve fruit exposure.
• Vines per hectare: The density of grapevines planted in a vineyard, impacting vine competition and grape quality.
• Viticultural zone: A specific grape-growing area with defined characteristics, often used for regional wine classification.
