One thing you wrote made me curious: That good wine box -- will a wine box from another batch also impress as much? I assume one of the problems with the cheap stuff is the std deviation values?
I might add that I got a Moldovan 2 bucks wine in a PET bottle this week and quite liked it. :-)
(I prefer dry red Spanish that you almost have to chew (I think the English term i s "rich"?). I should probably just admit defeat and replace the wine with a bit of vodka in espresso. :-) )
Edit: Hmm, I guess the cheap stuff is blended in giant volumes and hence consistent? Thanks for the information, lisper. I should try to widen my experience.
