can't tell you specifics because I have never done this, but I can say that you need not worry about oxygen permeation with PET. But you may get oxidation from the transfer.
Sounds like you really need another corny!
Beer, happy Produce of our Isle/Can sinewy Strength impart,
And wearied with Fatigue and Toil/Can cheer each manly Heart.
Labour and Art upheld by Thee/Successfully advance,
We quaff Thy balmy Juice with Glee/And Water leave to France.
Genius of Health, thy grateful Taste/Rivals the Cup of Jove,
And warms each English generous Breast/With Liberty and Love!
(Rev James Townley, 1751)
