Castellare di Castellina is a Chianti Classico estate in Castellina in Chianti, Tuscany one of the established mid-size estates in the historic heart of the Chianti Classico DOCG. The estate is known for I Sodi di San Niccolò, an IGT Toscana from Sangiovese and Malvasia Nera grown on the estate's San Niccolò vineyard one of the original 'super-Tuscan' expressions that predated the DOCG reclassification. Standard Chianti Classico and Chianti Classico Riserva are the commercial backbone.

I Sodi di San Niccolò is the estate's flagship for premium Italian red by-the-glass service a named-vineyard Sangiovese blend with cellar track record and collector recognition.
