The Bacchus Barrier™ - TCA Performance

This graph shows the TCA transmission rate for natural corks containing up to 10 ng/L of TCA coated with Bacchus Barrier™. Despite such levels of TCA in the cork, TCA in the wine remains below discernible levels for up to 4 years.

The Bacchus Barrier™ - Oxygen Performance

Bacchus Barrier™ has a barrier performance to oxygen of 2.0 cc/ m2/ day. This means that there would typically be an oxygen transmission rate of 0.0005 cc per cork per day through the Bacchus Barrier™. Corks with faults such as cracks, which would otherwise allow high levels of oxygen to permeate, show greatly improved performance when coated with Bacchus Barrier™. The overall effect depends on the cork employed, the diameter of the bottle neck and other factors such as the quality of the glass used.

Bacchus Barrier™ also helps prevent random premature oxidation due to the natural variability of corks. As a result the winemaker can have confidence that for a given cork type he will see consistent results.

TCA is 2.4,6-trichloroanisole.
