Tuscany, Italy
From the winery website: 
The Rancia vineyard takes its name from the historic Rancia farmhouse, once a Benedictine monastery. Located in Castelnuovo Berardenga at elevations ranging between 400 and 420 metres it has a fine southwest-facing exposure. The more recent plantings utilize genetic material from massal selections gathered from the old Rancia vineyard. The soil is composed of limestone-derived alberese classic to the Castelnuovo Berardenga area and of galestro marl in some areas. First vintage was 1983.

The 2020 Chianti Classico Riserva Rancia shows beautiful minerality with dusty notes of crushed limestone or flint. This is the wine's special signature, and it shines through in a warm vintage such as this. Rancia also offers an upfront quality of red and purple fruit tones. The 2020 vintage displays pretty concentration and richness with wild cherry and plum, but ultimately the wine leaves you with that elegant mineral sendoff. (ML)

Intense, with complex flavors of cherry, blackberry, violet, mineral and leafy underbrush, this red is silky and verges on racy. Harmonious and persistent, with a long, resonant aftertaste that echoes red fruit, mineral and savory elements. *Highly Recommended* (BS)
