Saxum is Latin for rock. You could even say rocks are a running theme at Saxum Vineyards. Parts of the estate’s James Berry Vineyard are notoriously rocky, as are most of the other vineyard sources. Several labels nod to rocks in the names, e.g., Broken Stones, Bone Rock, and Heart Stone. Whereas most growers curse their rocks, piling them at the best-forgotten edges, rocks are embraced by owner/winemaker Justin Smith.
