Massimo Lentsch and his family are one of the members of the nearly 600 year old `I Vigneri` guild. In accordance with their traditions vines are densely planted, but individually trained up untreated chestnut poles, not along wires, in a quincunx pattern. Viticulture is very much according to biodynamic principles, but without certification. Tenuta di Castellaro is all about the winemaking heritage of Lipari; recovered sites, and a mix of old vines and new plantings. They make wine from indigenous varieties naturally suited to the volcanic soils. All their vineyards are cultivated according to the albarello method, traditional also on Mount Etna; high-density, head-trained bush vines.
