The canopy consists of the portion of the grapevine that is above ground. This includes the shoots (lateral shoots, tendrils and petioles) as well as the leaves and the fruit. Many viticulturists also include the trunk, cordon and canes as part of the canopy, but this is not universally accepted. Many techniques are employed in managing the canopy to control the health and yields, while maximizing the quality of the wine produced from its fruit.
