Let me tell you what you already know about wine bottles. They are large, heavy, inconvenient to pack, always in peril of breaking and, once opened, lousy at wine preservation. You want wine on your outdoor adventure but you don't want to lug that stupid bottle. The solution is the Platy Preserve Wine Preservation System. Before leaving home (or during your trip), pour a full bottle of your favorite vintage into the Platy, squeeze the air out and cap it - your wine will stay perfectly fresh until you're ready to drink it. If you drink half a bottle, just squeeze the air out and cap it. Your wine stays fresh.
A Platy full of wine is smaller and lighter than a glass bottle, and it is pliable, shatter-proof and very durable. How durable? One season on the road, I demonstrated the durability of the Platy by standing on a full one upwards of 100 times! After three months of doing that demonstration, I made the mistake of bouncing on that full Platy and eventually blew out a seam, but you get the point: the Platy is one tough flask.
When you have a glass bottle, it takes up the same amount of room in your pack coming and going, full and empty, and breakage is always a danger. An empty Platy, on the other hand, can be flattened and/or folded for out-of-the-way packing. Of course, it can also be refilled!
As you already know if you're a wine enthusiast, the three environmental factors that damage wine are oxygen, temperature (especially high ones) and ultraviolet light. The PlatyPreserve solves the first factor by isolating your wine from oxygen, and you can deal with the other two factors by storing your Platy in a cool dark place. Ideally, the storage temperature should be held constant at 50 to 52 degrees F. Higher temperatures and bright sun or fluorescent lights can damage wine no matter what the container.
The Platy is marketed for wine preservation but works fine as a booze flask or water bottle. Doesn't work with beer (filling the Platy with beer is a real pain in the butt). And the Platy is not just for outdoor adventuring - Maria and I use them at home, too! Oh, and if you didn't already think of it, these make great, inexpensive gifts/stocking-stuffers.
