Growing winegrapes at high elevation is challenging. The wines that result are intense, true to terroir, declarative. The vineyards experiment with varietals and coax the clusters to ripeness in the unique mountain microclimates. The mountain-and-foothill wineries and winepeople work hard. The flavorful wines, sourced from the fruit of the mountains and foothills in various parts of the USA, benefit from the clean air and deep breathing that comes with life at 1300-feet-and-above.
