Not being a Antinori fan, I'll pass on the Tignanello. But if you enjoy Brunello Di Montalcino's, get a bottle of Poggio Di Sotto once. The regular Brunello (not the riserva which ha to age quite a lot). Better prices then Soldera or Biondi Santi but equal quality. You can keep the Napa wines also. God, I'm really not a Cabernet Sauvignon guy.
This is my faaaaaaavorite wine!

Can't comment on anything over $50. I buy $12-20 wines and if I had anything over $50, I wouldn't have known so
