Medieval grape harvesting. The harvesting of wine grapes is one of the most crucial steps in the process of wine-making.The time of harvest is determined primarily by the ripeness of the grape as measured by sugar, acid and tannin levels with winemakers basing their decision to pick based on the style of wine they wish to produce.
The time of harvest depends on a variety of factors – most notably the subjective determination of ripeness. As the grape ripens on the vines, sugars and pH increase as acids (such as malic acid) decrease. Tannins and other phenolics also develop, which can affect the flavors and aromas in the resulting wine.
A green harvest is the removal of immature grape bunches, typically for the purpose of decreasing yield. The removal of the bunches while they are still green induces the vine to put all its energy into developing the remaining grapes.

The Grape Harvest Festival is expected to draw more than 2,000 people to celebrate family, food, fun and agricultural discovery at Florida A&M.
Large bodies of water, such as Lake Geneva in Switzerland, can have a moderating effect on the climate of a region.. Beyond establishing whether or not viticulture can even be sustained in an area, the climatic influences of a particular area goes a long way in influencing the type of grape varieties grown in a region and the type of viticultural practices that will be used.
