Wineries use 'dry soak' screening for large format bottles. Few moments are more embarrassing than opening a bottle of wine for guests or customers and finding that it’s corked. The problem is only compounded when a winemaker is opening a 12-liter bottle in front of a large audience with glasses outstretched. “It wasn’t a positive moment,” recalled Christiane Schleussner, assistant winemaker from Silver Oak Cellars in Oakville, Calif., about an occasion that she remembered well. After that happened, her management said, “We can’t let this happen again. Fix it.”
