The goal of most grape growers is to produce high quality grapes for wine. For making the best wine, the highest quality grapes are often the most mature and uniform. In today’s quality driven marketplace, the best fruit will command the highest prices and the greatest demand. Climate, environmental circumstances, and cultural practices are all important in determining fruit quality, however, few techniques may impact fruit maturity more than regulating yields to achieve a balanced vine and uniformly mature fruit. A previous “Timely Viticulture” discussed estimating the existing crop in the vineyard. Once tons per acre or pounds per vine data is collected, it is easy to work backwards towards a targeted yield. This issue will address adjusting the crop level for the desired outcome.
An experienced grower will know his site and will develop a sense of what the optimal yields are to achieve full ripeness in certain varieties and fields.
After the target yield has been determined, the fruit must be thinned to the proper level.
