Erbaluce
Erbaluce is an ancient Italian white wine variety suitable for a variety of wine styles, including sparkling, dry, and passito. It is considered vigorous and productive in Italy, where it is traditionally long-pruned and grown on a pergola. In a San Joaquin Valley trial where the vines were trained to bilateral cordons, spur-pruned, and supported with a two-wire T-trellis, the yields were low, but fruit and wine quality were high. Simulated mechanical pruning greatly increased yields without affecting soluble solids accumulation, so adequate yields should be attainable by adjusting pruning practices.
