Pollination Pollination and the Vine
After the vines lay dormant through the winter months, the plants begin to spring anew as the temperatures warm up and the vines begin to produce their new leaves. When the buds, or new growth on the vine, begin to “break” out and soak up the sun they start to flower. In mother nature flowering often means that it is time for pollination by an outside organism however wine grape varietals are hermaphroditic, meaning they posses both male and female reproductive organs, allowing them to self-pollinate. This type of grape is preferred in winemaking because there is no need for the vines to be pollinated by an outside organism such as a bee or other insects.
While we do not need to rely upon insects for pollination, this period can bring with it some difficult circumstances. For example, a cold front can prevent the vines from properly maturing if pollination is interrupted by an abnormal cold streak. Luckily, California has very even growing seasons so rogue weather is a rare occurrence.
