Best wineries near Montepulciano, Italy?

Visiting Tuscany next year and looking for recommendations on the 1-2 best wineries to visit near Montepulciano.

Also wondering if there is a wine bar/enoteca in town where I can taste some unicorn wines from other regions (mostly Brunello and Piedmont) without having to venture out to those places. Wanted to avoid using a day for Montalcino since there’s no much to do in that area aside from wineries.
