THE CORE represents the very best of Buoncristiani Cabernet Sauvignon from the 2015 vintage. Each year the four Buoncristiani Brothers craft multiple single vineyard Cabernet Sauvignons from premium Napa Valley vineyard blocks, and THE CORE is the culmination of meticulous blending of carefully selected lots. Choice barrels are folded together slowly over the course of two years, diligently creating a balance of power and elegance, and then captured in bottle without fining or filtration. At the heart of the Buoncristiani portfolio is THE CORE.
