Sum of all diverse activities during the annual vegetation cycle in the vineyard with corresponding tools, measures and systems in order to obtain as physiologically ripe and healthy grapes as possible as the basis for high-quality wines. A catchphrase frequently used in this context and often used on winemaker websites is "The quality of the wine is already decided in the vineyard" with sometimes the addition of "The measures in the cellar are limited to controlled (non-invasive) doing nothing". It is not quite as simple as that, but there is no doubt that omissions and mistakes in vineyard management are difficult or impossible to rectify in the cellar.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.Dr. Edgar Müller
