While it’s hard for us to imagine having any left over wine, EVER, there’s always a first time! Three suggestions: #1: Move the wine to a smaller bottle (the bottle needs to be full to the top). #2: Gas it! Private Preserve is the best-known brand. We sell it – most wine shops do. #3: Go get a vacuum pump at your local wine shop. What do they all have in common? They eliminate the enemy in the headspace: air.
