When I have the opportunity to prove that Chianti Classico can show grace and pristine fruit quality akin to Red Burgundy, I use Giovanna Morganti's Le Boncie as my first example. I implore you to trust this will be your moment of clarity for Sangiovese.
Importer Neal Rosenthal's Montevertine is a benchmark for the region, but his other discovery, Le Trame, better illustrates Sangiovese's sometimes elusive, fruit-forward profile and silken tannins. Also consider Chiesamonti, which comes from a one-hectare parcel in Castelnuovo Berardenga. The stonier soils here result in a wine with brighter red fruits and a long saline finish (Differing from Giovanna's other wines that exhibit more fleshy characteristics). These two Chiantis are all class.
Giovanna farms her five hectares using organic and biodynamic principles. I could go down the rabbit hole on farming, fermentation, and aging specifics, but I'd like to cut this one short and say: This is a profound wine that's a joy to drink. I've lost count of the number of times I've used this bottling to convince friends that Sangiovese can be fun, approachable, and deadly serious. Below is a photo from my 2017 visit and the gorgeous color of the Stockinger barrel sample that had me in love.
