There’s an art to savouring champagne, but all except the most seasoned champagne connoisseurs are au fait with the ins and outs, the rituals and the protocols of the experience. For the rest of us, especially those who’ve always wanted to know how to saber like a pro, the perfect temperature to serve, or even the appropriate stemware to proffer your guests, there’s always G.H.MUMM’s tongue-in-cheek iPhone app, Champagne Protocoles, to count on. It’s available for download now from the Apple Store www.apple.com/itunes. Meantime, enjoy the stylishly witty video that the esteemed French House has produced. Santé!
