Parks Redwine – wine importer and “Dean” of American wine competitions

It works well.

The Durand combines two very tried and proven technologies.
While it will work on any cork, it is nearly essential for older
corks in prized bottles.

Supposedly the average “life span” of a cork is about 25 years.
(Sweet wines can shorten this to less than 20 years.) If you
have a fine wine from a vintage prior to 1985 you need to own a
Durand – or run the risk of a crumbling or broken cork. The older
the wine, the higher the risk.
