1. Trade the ice cubes for “wine cubes.”
Even at something as informal as a backyard barbeque, adding ice cubes to wine is a big no-no. The reason has more to do with science than snobbery: As the ice melts, the water dilutes the wine, throwing its flavour profile seriously off-kilter. The easiest way around this dilemma is to fill your ice cube tray not with water, but with the wine you’re serving. That way, when the cubes melt, they’re simply adding more wine to the glass!
