(Paolo's) pride in his estate, on the western side of the Chianti Classico zone, is evident at every turn of the road... As we tour the vineyards or taste the wines, there is one theme to which De Marchi returns again and again: the typicity of Chianti. It is, for him, more than a philosophical or stylistic debate. It has to do with the relation of wine to the land on which the vines are grown.

Proprietor Paolo De Marchi has left an indelible and highly personal stamp on Isole e Olena, and all of Chianti Classico for that matter... De Marchi stands apart from many of his colleagues for his vocal opinions and intense dedication to the vineyard above all else. Since taking over his family’s estate... De Marchi has transformed Isole e Olena into a powerhouse.
