Local lad Andrea Mantengoli has been farming Cantina La Serena since 1988. The farm is next door to Cerbaiona and Biondi Santi, on the eastern shoulder of Montalcino. The vines here are grown at 200-400 metres’ altitude. This covers a range of different soil strata: atypically white and yellow tufo; sand; schist; and galestro. Each gives depth and detail to the wine. Andrea and his twin brother, Marcello, manage the estate. They are proudly organic, and they use some biodynamic methods. In addition to grapes and vines, the ecosystem here includes spelt, grain, olives and honeybees.
