The market for organic food products in the Netherlands is growing; however, supply shortages are hampering the grow th of the market. The Republic of South Africa (RSA) has the advantage of being able to produce organic food products during the European winter seas on, as it is located in the southern hemisphere. Sourcing organic products from the RSA could therefore amelio- rate the current shortness of supply.

Grapevines require annual pruning to remain productive and manageable and to achieve consistent yields. Dormant vines are pruned in early spring to adjust pruning severity to account for midwinter cold injury. Growers control production by pruning to achieve consistent yields. Grapevines can potentially produce 10-12 tons per acre (average is 5 tons). Allowing vines to overproduce reduces vigor and future yields.
