Unusual Closure Tasting At Master of Wine Seminar Very Illustrative


Date: 02/13/09

by Lisa Shara Hall
A closure tasting was held Tuesday in Yountville, California at the annual Master of Wine seminar for enrolled students. The tasting was also attended by about a dozen Masters of Wine.

Each taster received four glasses filled from differently closed bottles, each otherwise the same 2004 Sauvignon Blanc from Washington state. The participants were asked to vote on what closure they thought closed each wine, and which wine they preferred.

The first wine showed very oxidized characteristics, and most thought it was from the plastic cork, which was correct.

The second wine showed some oxidized character, some evolution, and was thought to be cork by many people. It was closed with an experimental Supreme cork called X2, still a plastic cork, but with a bit of flexibility to the plastic.

The third glass was fresh and the most aromatic. It was closed with a new screw cap with a foam liner.

The last glass showed reduction, and a leaner mouthfeel, with a shorter finish. It was closed with a straight screw cap, with an aluminum liner.

The preferred glass was overwhelmingly the 3rd wine.

No cork closure was shown.
