'Permeability screw top' invented by American students

Keller's research team has developed the new screw cover, is to reduce the TCA contamination caused by cork, contaminated wine has typical of musty, decomposition and the wet sacks odor characteristics. And 20% are usually with earthy wine cork pollution, sootiness flavour, taste, or canned mushroom flavor. Statistics show that the wine industry because of TCA ( 80% of the cork pollution) Cork pollution caused by huge losses, at the university of California study reported in 2001, 2% ~ 7% of the wines from TCA contamination in the United States, this year lost more than $two hundred and eighty million. Supermarket shelves, each about 20 cosmetics packaging production of wine has a cosmetic packaging production is polluted.
this high-tech cosmetics packaging production cover wine grape cultivation by Davis, a university and brewing Tim keller graduate ( Tim Keller） With his teammates Kevin ( 凯文·沙特朗) , Diana ( Diana Mejia） Joint invention, keller entrance in napa and sonoma county before work in the wine for ten years. To solve this problem, people invented a synthetic cosmetics packaging production, but synthetic bring more oxygen into the wine, shorten the product shelf life, may make the flavor of the wine exudes nail polish. Now widely used spiral cover with sealing, but after the wine aged will emit the smell of burning rubber fire match stick. , keller team developed a 'screw top' permeability, small vent lid, there is a liner made of thin metal rotation layer, and a porous polymer. Liner is designed for special varieties of wine custom, a moderate amount of oxygen are allowed. At present, the invention is applying for national patent. Keller said: 'if you open more cosmetics packaging production the same wine, you will note that because of the difference caused by different degree of oxidation. Our cosmetics packaging production can control the degree of oxidation of the wine. 'The new cosmetics packaging production permeability cover sold only 20 cents each, are cheaper than cosmetics packaging production cork and metal cover 10 or 11 cents, a synthetic plug with screw top your 5 points.
