Barbera d'Alba Il CerretoRoberto Voerzio is undeniably one of the stars of Piedmont and a Barolo producer with a world wide following, his philosophy is a simple one; from the healthiest lowest yielding vines, in the greatest plots, come the very finest wines. His vineyard management is meticulous and covers hard pruning, green harvesting, pruning, and leaf thinning which, together with his policy of having high planting density, result in an exceptionally small production.
