At an outdoor party more white wine will probably be used as a thirst quencher. And the season - red wine is consumed more in winter. Occasionally, you can offer a good client a special deal on wine if your property has broken cases in inventory. Pay attention to your glassware. Glass size affects consumption.
Larger glasses tend to promote more consumption.
Use the correct glass for the type of wine. According to Korbel, when serving champagne, the best method of chilling is with ice. To achieve the best benefit from ice, fill the ice bucket or tub with equal parts of water and ice. Adding cold water allows for a more rapid exchange of heat out of the wine or champagne. Serving temperature can be achieved in 20 to 30 minutes.
