This nifty new system allows wine drinkers to sample a bottle without pulling the cork. It works by inserting a small, narrow needle through the cork and letting you pour right through it. The system uses argon to pressurize the bottle and push the wine through the needle. Once the needle is removed, the cork seals itself. For this reason, new, natural corks are best to use with this. Synthetic corks will work, but a small hole will remain in the cork, which will allow some oxidation of the wine. A good gift for anyone who likes to sample many new wines in an evening.
