Dear Miranda, Our Business Manager (and ex-sommelier) Tiffany does this too. By coating the insides of the wine glass with the wine, there’s more surface area from which aromas can emanate, amplifying the wine’s flavor. Because most wine glasses have a convex shape, there’s little chance of spilling the wine if you do this carefully. For my part, I like to coat the inside of the glass by vigorous swirling, but both techniques work.
