But that's been discussed here before. Somewhere.
I prefer white to red mostly with gwertzakermumble being my favourite grape since it tends to be sweeter. Gah, I had a savigaun blanc on Friday by some chick* named Kim from New Zealand that tasted like worn gym socks! My girlfriend thinks it's just prickly pear or some sort of pear and something else. That may very well be the case but they definitely used worn gym socks at some point during a filtering stage!
* I presume it's a chick. I know Kim can also be a guy's name but that tends to be less common.
