In an unopened drum the shelf life of Tea Tree Oil is a few years. In an opened bottle, with good cap and seal the shelf life is up to 10 years at least. We conducted 10 year shelf life trials, completed in 1998, and only the oil in the few faulty bottles, caps and seals was badly affected in that time.
