Chianti Colli Fiorentini is the subzone of Chianti that immediately borders the city of Florence. Viticulture has been practiced in this undulating landscape for hundreds of years, and the zone is noted for its Sangiovese-based red wines that are well-rounded, fruity and easy-going. Colli Fiorentini wines tend to lack the prestige of Chianti Classico wines, and are commonly used to fill carafes at local Florentine restaurants.
The zone essentially wraps around the northern part of the Chianti Classico zone, with its northeastern corner extending up into the mountains behind Fiesole, bordering the Chianti Rufina zone. Colli Fiorentini also takes in a section of the Val d'Arno, as well as the valley of the Pesa river in the southwest. It is one of the lesser known of Chianti's seven subzones, but many producers still choose to append the title to their wines, which fall under the umbrella Chianti DOCG.
The terroir here is not too far removed from the rest of Chianti, with its Mediterranean climate and limestone-rich soils. Vineyards can be found on the south-facing slopes in the area, reaching as high as 1000ft (300m) above sea level. Warm, sunny days and cooler evenings give the berries good ripening opportunities without compromising acidity. Moderate rainfall throughout the year keeps the vines hydrated, but the stony soils ensure good drainage, reducing disease pressure and restricting canopy growth to an extent.
As is the case for most of the Chianti subzones, Colli Fiorentini wines must be made from at least 70 percent Sangiovese (although in practice this proportion is often much higher). Sangiovese's herbal, rustic character is tamed by other local varieties like Canaiolo and Colorino, and sometimes by more recognizable international varieties like Cabernet Sauvignon and Merlot.
