Difference Between Wine Screw Caps and Natural Corks
Inputtime:2014-03-03 09:50:30
  Compared to cork, screw caps prevent the wine faults of oxidation and of cork taint, and are easier to open. Screw caps have a much lower failure rate than cork, and in theory will allow a wine to reach the customer in perfect condition, with a minimum of bottle variation. Cork, of course, has a centuries-old tradition behind it, and there are also concerns about the impact of screw caps on the aging of those few wines that require decades to be at their best. Some argue that the slow ingress of oxygen plays a vital role in aging a wine, while others argue that this amount is almost zero in a sound cork and that any admitted oxygen is harmful.

  Producers in Champagne have aged their wines under crown cap for quite some time with no apparent outcry. No manner of removing the cap with the grace of traditional cork pulling has yet emerged.
