n 1982 Sir Peter Michael established the Peter Michael winery on a square mile of rocky volcanic ridges that form the western face of Mount St. Helena in Sonoma County. From the beginning, the wine growing philosophy was modeled on the French tradition infused with a few modern influences: One, the vineyard terroir would be the single most important feature. Two, the wines would be elegant rather than overstated. Three, there would be a hundred-year commitment to the development of a great estate. Given this commitment to the product, only a limited quantity will ever be made.
