Despite the fashion for replanting, many old vineyards remained across California. They were planted with Zinfandel, and a mix of grape varieties brought by Italian immigrants. Most of these older vineyards were dry farmed (not irrigated), with deeply rooted vines. Some winemakers—older ranchers and their children, as well as newcomers—valued the fruit on older vines that produced fewer grapes, but with more intensely concentrated flavor. They sought out old vineyards, and planted new fields with old varieties.
