Can I use screw cap bottles for my wine?
Sure! Studies are finding that in many ways, screw capped wines are actually better than natural cork and synthetic corks.
The number one reason to use screw caps, is that you will not encounter any wine that has "cork taint," developed from a fungus that grows on corks and spoils wine.
Studies are also finding that screw caps may just preserve the freshness of your wine better than synthetic corks and at least as well as natural cork. As there is more room in the neck of the bottle, you may wish to use Private Preserve (A6031) to purge the head-space of oxygen, preventing oxidation, before you cap the wine.
