About Justin Vineyard: We planted our first vineyard back in 1981 with a mission to make world-class Bordeaux-style blends. Since then, we’ve expanded both our knowledge of viticulture in this unique region as well as our acreage. Soil: Rich in fossilized limestone from eons of marine deposits, JUSTIN’s soil is ideally suited to creating big, Bordeaux-style reds. The limestone “stresses” the vines, producing grapes that fully express their varietal character. Climate: Paso Robles’ distinctive microclimate offers the widest day-night temperature swings of any grape-growing region in California. The hot days allow the grapes to develop intense flavor, while the cool nights create great structure and balance.
