DescriptionViticulture- learn the techniques and become a successful Vitculturalist. This course will help you develop an ability to select and cultivate appropriate varieties of grapes in different situations, and provide the knowledge to make informed decisions about the management of a vineyard. There are ten lessons covering the history of viticulture, the current state of the industry, wine and table grapes, dried grapes, cultural practices (trellising, soils, planting, pruning, irrigation, pests & diseases); vineyard design, improving quality, harvest & post harvest procedures, winemaking, marketing and more.

Suitable regions for good quality grape production are determined more by climatic similarities than geographic location. Regions that have mean annual temperatures between 10 and 20 degrees Celsius are the most conducive for quality wine production. World distribution of viticulture is bounded by the 50∞ line of latitude, both north and south of the equator. However, even within these general parameters, grape vines are not suited to places where leaves do not fall from the vines over winter (due to warmth) or where winters are severe and summers are short.
Assessing regional suitability to grape production is not
absolute. Variations in local climate caused by topographical
characteristics can greatly affect the feasibility of production.
For example, elevated areas in warm climate regions may yield the
cooler temperatures required to produce good quality winemaking
Several parameters are commonly used for assessing growing conditions. Degree Days and Latitude-Temperature Index (LTI) are two such measures. A region with a higher latitude may have cooler mid-summer temperatures but may not be inhibited from good production when offset by a long growing season. The Bordeaux region of France and areas of Washington state in the USA may fall into this category
