Screening Cork Shipments with Group Soaks

A Successful Application of Chemical Cork Screening Methods Presented by Gordon Burns ETS Laboratories - Wines & Vines Packaging Conference - August 2015 - Napa CA

Summary : A statistical analysis from 50,000 group cork soaks over the past four years. The report illustrates that the vast majority of CQC natural corks are now below 2ppt (94%). Presents details on new, more stringent screening techniques that are designed to identify bales with a majority clean corks but with small percentages (1-3%) of high TCA corks. Such cork populations are now rejected at the “lot level” – not just the individual bale that reveals a higher score.
