Chianti Colli Senesi is one of the seven defined sub-regions of Chianti that are distinct from Chianti Classico. This is the largest and most significant sub-zone, bordering the southern end of Chianti Classico in the hills around Siena and running all the way down to Montalcino and Montepulciano.

Being a large region, there is a variety of micro-climates, elevations, exposures, and soil types. This can make for a mixed bag of styles depending on the exact location of the vineyards and the aims of the individual producer. In general; however, well made examples are easy drinking and perfumed, while better wines almost universally provide good value. The varietal and aging guidelines are the same as those for the broader Chianti DOCG. (Wine/Appellations)
