“After decades spent walking sun-warmed vineyard rows at harvest, sharing early-morning coffee with winemakers before the first crush, and tasting in candlelit barrel rooms far from the tourist path, we’ve learned one truth: California wine is as much about place as it is about the pour. Every hillside, fog line, and patch of soil tells a story—one you can taste in every glass when you know where to look.”
