I love port ... not a fan at all of tawny ... and my default choice is "six grapes". I think it's very good, and if there is no reason to switch, I won't ... but I'd love to upgrade a bit. Perhaps something better and a little subtler ? Again, I don't like tawny, so I don't want to go down that fork at all. I've tried 6-7 other bottles, with pricing between $15 and $50 and while one of them was as good as six grapes, none were better. I have also tried some of the Grahams "Vintage" ports, although I don't remember the year ... again, good, but no reason to switch from six grapes. What should I try that would really knock my socks off ? Priced less than $100, please... Thanks.
