Query: An essential item when you don't want to drink it all now

This is a great tool for anyone who likes wine. I use mine all the time. It does preserve wine well and is quite easy to use, but I would encourage you to get extra stoppers and to use only Vacu Vin brand. I've found that other brands don't always work very well.For red wines at optimal drinking age, don't rely on the vacu vin for more than 1-2 days, 3 at most (and that will be too much for some). You may find that younger wines even benefit from a few days. This is worth trying if you open a bottle and find you don't like it. Or, if it's that bad, preserve it for cooking.Enjoy!
