Castello di Montepo - any experience with these wines?

Was invited to a wine dinner where this producer’s wines are being tasted. The background info I got for the dinner explains this is the current winery of the 7th generation of the Biondi Santi winemaking family.

I’m unfamiliar with this producer and nothing meaningful came up when I searched the board. If anyone collects or has consumed their wines would welcome your thoughts.
