It’s time for the big show. Make sure you are holding the bottle at a 45-degree angle, so as not to spill any precious cargo on the floor. The motion should be fluid and mildly forceful. Start at the bottom and slide the knife up the neck and…pop! Make sure there are glasses to capture the spillage — especially if you’re using a Champagne as fine as Moët & Chandon Imperial. And you might be wondering about glass. As in, do the shards fall into the bottle? Answer: No. The pressure forces the cork outward. The break is clean and there should be no glass. Good luck!
