here’s a lot of wine history in and around the small town of St. Helena, which many consider to be the fulcrum of the Napa Valley. Two of the Big Four – Beringer Vineyards and Charles Krug Winery – were among the earliest and most important wineries (along with Rutherford properties Beaulieu and Inglenook) to be founded on the northern outskirts of town. While later, in the early to mid-20th century, there was Louis M. Martini Winery and Sutter Home Winery.
