I didn't realise we had to stay on-subject. Well, I'll try. So for people with genes such as ours, the best Sardinian wine is Cannonau, anything over 13%. This is a strong red-black wine, more ore less the wine equivalent of Guinness. As regards actual bottles I'd recommend Nepente from Oliena or Orturù from Mamoiada, also Mamuthone from Mamoiada but that's quite expensive. Don't know if any of these reach England.
