Our wine is a delicate product and needs proper handling for maximum enjoyment. Do not allow wine to sit in a hot car or leave it in the trunk. Minimize temperature fluctuations. These things can cause a pressure increase inside the bottle. Keep wine upright during transport and for at least 24 hours once it reaches its new destination before lying on its side. If these practices are not heeded, the bottle may leak, and you may find some mold growing on the top of the cork when removing the capsule, however, the wine in the bottle should be fine. Once opened, wine will react with oxygen, and is best consumed within 36 hours.
