Susan is a pet nat! Hello Susan. It is made from a very exotic white grape variety called fernao pires which is made as a light orange win and the rest is brightly flavoured montepulciano which is macerated for seven days and immediately pressed off, so it comes out as a lightish red wine. Get it? Orangey white meets light red in a pet nat vibe. Fun, but in capital letters. FUN. And delicious.
