I'm a wine lover, but by no means a wine snob. I drink what tastes good to me, regardless of the label. Had some wine snob friends visit for dinner recently and he decanted a 2007 cab-sav for the dinner. We had already drank one bottle of it (and plenty of chardonnay before dinner) so I was wondering the reason for this. Does decanting a 2007 wine really make a difference? Or was he just posing because he wanted to show off using the decanter, funnel and screen? Does a 2007 wine even have any sediment that could be caught in the screen?
