....and what about Wine Shield?

  • a

...starting a new thread because the last one is getting a little too tecnical for me.

Any tooughts on "wine shield" by http://www.winepreserva.com? .....the one with the plastic circle to cover the wines?

  1. cute but ... probably does not work well.

    from one of the video, it show in real life that some wine sit on top of the "shield" that will turn bad faster than the rest of the wine and will be poured when serving a glass and will "contaminate" the rest of the wine.

    just my 2onces...

    1. I don't see how a thin plastic disk floating on top the wine would work.

      I just read the Technical Data and white paper. Their tests compare the WineShield to doing nothing -- kinda bogus. Wine Shield should be compared to other ways to preserve wine -- like VacuVin, Private Preserve or 100% argon. The idea that those tests are not listed is a big red flag -- it means the product didn't perform well.

      The tests they do list show a bad pattern. They list four that measure aging using the Wine Shield, and only one tells you anything important. The results of a much more important test that measures wine aging were left out -- a bad sign. The third test is ambiguously worded and the fourth has no bearing on a wine that's been open a short time -- all red flags. I know one of the labs where the wines were tested, so the proper tests were done but Wine Shield left out results -- probably because they showed poor performance. Also bogus: The paper is padded with stuff unrelated to wine aging (cork taint and scalping), in a misguided attempt to make the paper appear more scientific. Weird. Sorry, I got all geeky/technical on you again.

        Maria,

        your explanation was excellent. You competently analyzed the likely effectiveness of this product.

        I guess I will cary on with vacu vin and accept the fact that wine...like many things in nature(including ourselves) evolves with time and oxygen...sometimes for the better and sometimes not...

        1. re: Aosta

          Transferring to smaller bottles really works well. Try that. I'm sure there are canisters of 100% argon where you are, Aosta. Call some nearby wineries and ask.On the other thread, I gave some other leads in Italy. Tanti auguri.

          1. re: maria lorraine

            Thanks, Maria Lorraine.
            Transferring to small bottles is what I have been doing for nearly 20 years.
            I don't see any reason to do it any other way.

          ML,

          You forgot 100% Helium. Then, when you taste the wine the next day, you can entertain your guests with that funny Disneyesque voice... [Grin]

          I would agree that testing against nothing but an open jug is probably not gonna' sell me.

        3. I was given some of these things by someone who really believes in it and has some real wine cred. His evaluation was that the shield PLUS Argon gas would be about the best thing short of a full-on closed dispensing system.

          I haven't really tested the shield myself but plan too soon. I HAVE placed one in a half-filled bottle and watched what happens. The disk just doesn't seem to lie flat enough or create a complete shield that looks like it would protect the wine from the air so close to it. Hard to believe it doesn't work at all, but how well is a different matter entirely. I'm always interested in trying out this kind of thing though.

          1. re: Midlife

            I tried Wine Preserva a few times so far. In my unscientific tests, I can say that it is better than nothing and perhaps on par with Private Preserve.

            It's gimmicky.

            But agree with Maria that smaller bottles and 100% argon are the way to go until otherwise told.

            1. re: kaysyrahsyrah

              I have several canisters of various inert gasses, and was gifted a rather elaborate system, that uses large, honkin' cylinders of other inert gases and has nozzles and pipes and all sorts of Dr. Frankenstein stuff. All that it lacks is a chiller. I tried it, along with my normal - Vac-u-vin + fridge, and soon went back to the Vac-u-vin + fridge. Still, I appreciated the person's thoughtfulness and the $'s that they spent on little ole me.

              PS - it works quite well, but there is a whole procedure to use it, and wines do not stick around my house long enough to justify the device. I'm lazy that way.

            2. re: Midlife

              You, of all people here, should have tested, as I would follow your advice.

              Inquiring [SIC] minds want to know!

              1. re: Bill Hunt

                I'll give it a try soon, Bill....... but I'm biased toward Argon. It'll be like a voi dier proceeding....... can I put my biases aside?

            3. Not what I was expecting. I was thinking about the little mylar disks, used to pour in a dripless manner.

              This is new to me.

              What do you think of it?
