CQC Study of Disk Performance in Preventing TCA Transfer from 1+1 Corks

Study of the transfer of TCA to bottled wine with various components used in the manufacture of technical corks - February 2010

Summary: Results of a 24-month study of wines bottled with technical corks made with components selected for either high or low TCA concentration.  Final results showed that disks with low TCA concentration successfully inhibited TCA migration from agglomerated bodies selected for high TCA concentration.
