Dear Triana, Apparently it does not. We could not find any scientific data suggesting that swirling in one direction is better (or even different) than the other. What IS important is that you swirl period. All wines—whites, reds and rosés—“open up” and seem more vivid after being mixed with air. The best way to swirl vigorously (and avoid a dry-cleaning bill at the same time) is to draw quick circles with the glass while keeping the foot of the glass on the table.
