The Wine Saver Pro preserves and serves fine wines from the bottle using inert gas to keep oxygen out. This means you can afford to open wines usually reserved for bottle service to offer premium wines by the glass to guests that would normally only drink a glass or two. Wines that normally oxidize in a few days stay fresh from two to four weeks on the Wine Saver Pro. Your guests will enjoy the highest quality pour, every time – and you’ll increase your profits through the margin.
