(Wines&Vines) - It took years of preparation, a name change and somewhere between $50,000 and $100,000, but the Pine Mountain-Cloverdale Peak AVA won TTB approval just about a year ago. Since then, the scant dozen grapegrowers and winemakers in this remote, high-elevation appellation in northeastern Sonoma County have founded an association, a website and are working together to build a brand focused on high-end, high-elevation Bordeaux varieties.
