Wine Stoppers, Kollea Wine Bottle Stoppers, Vacuum Wine Stoppers, Reusable Wine Preserver with Time Scale, Wine Vacuum Pump Wine Saver Wine Corks, Best Gift for Wine Lovers (2 Pack, Black)

We have purchased these twice now and they seem to work great on white wines and light-colored wines with bubbles but not so well with red wines. The red wines taste ‘off’ very quickly but the white wines and light-colored wines with bubbles fair really well, like impressively well. I personally don’t notice much of a difference in taste after a few days, even the minerality is well-preserved.Can easily get 4-5 days of semi-freshness with these stoppers.Even the awkward-shaped or larger bottle …tops that aren’t supposed to fit with these stoppers still work, you just have to shove the stopper onto the top of the bottle straight and well to form a seal, and then start doing the suction pumps and it sucks the air out well.

Wine stays fresh doesn’t loose flavor great product

Easy to use and only takes the one piece, the stopper to make the Vacum. Great

Use this on my wine. Vacuum works great and is easy to release.
