Vineyards around the world utilize different types of trellis systems for growing grape vines. Although there are differences between each of them, they all have several things in common. First of all, one purpose for the trellis, regardless of style, is to support the weight of the vines and fruit, which will aid in the growing and harvesting processes, as well as helping to manage vines for pest and weed control. In addition, because the grapes that are being produced are affected by the amount of sunshine the vines receive, a trellis is important to maximize the exposure of the leaves. In this way, the ripeness, flavor, aroma and color of the grapes can be optimized by the grower. Throughout past generations, varied forms of trellis systems have been developed, customized, altered and used. Following are the most common types of trellises used today.
