Factors affecting wine quality and style Flashcards
How does soil affect when quality and style?
The composition structure of the soil has a considerable effect resulting on the resulting wine. The geographic and chemical properties of the soil have influence.
Which types of soil are best suited for wine making?
Gravelly clay loam
Hard pan loamy sand
Hard pan gravelly clay loam
How does climate affect wine quality and style
Climate conditions are important factors in viticulture. The average yearly temperature must not be below 10°. The ideal average is 14°. 
What is the difference between macro climate meso climate and micro climate?
Macro climate is the climate of a large area such as a region
Meso climate is the climate of a specific vineyard site
Micro climate is the climate within the vineyard canopy
How do hot and cold climate affect wine
Too much heat will result in small grapes with tough skin and high potential alcohol and low acidity while too little heat will result in grapes high in acid and have less sugar and flavour
How does rain water and sunlight exposure affect wine quality and style?
Too much water produces bigger barriers with less sugar density, less alcohol, a weak body and less flavour
Sun Exposure enables the grapes to convert carbon dioxide and water into sugar
More sun ➡️ more sugar ➡️ more alcohol
Less sun ➡️ less sugar ➡️ less alcohol
How does location of vineyard affect quality and style of wine?
Most vineyards are located in mountainous slopes, valleys and plains with consideration of altitude and slope orientation impacting the temperature and sun exposure affecting the ripening process and flavour.
How does vineyard size affect the quality and style of wine?
Small vineyards often have more control over the quality of the grape and management
Large vineyards may have the technology but face challenges in managing consistency across 
How does grape variety affect quality and style of wine?
Certain grape varieties are associated with high-quality due to their flavour profile however the quality of wine ultimately depends on how well the grape variety suits the climate and soil
How does vine density affect the quality and style of wine?
grape density influences the concentration of flavors, tannin levels, acidity, yield control, and terroir expression in wine, ultimately impacting its quality and style.
How does vine pruning affect the quality and style of wine?
The process of selectively removing parts of the grapevine to control the growth and optimise quality
How does canopy management affect the quality and style of wine?
carefully managing the canopy, growers can influence the vine’s environment, optimize fruit development, and ultimately produce wines with desired quality, style, and expression of terroir.
How does irrigation affect quality and style of wine?
Involve supplying water to grapevines to ensure adequate hydration and provide healthy grapevine growth and development, especially in regions with limited rainfall or drought
