Ah, but it just says, “best if used by”, doesn’t really have an expiration date. ;^) [adapted from Peg Bundy]
("Medical Definition of empyreumatic. : being or having an odor of burnt organic matter as a result of decomposition at high temperatures creosote and other empyreumatic oils.")
Not a term you do not see used much at wine tastings! (Maybe Retsina, the traditional wine of Greece since antiquity. It has its own unique style due to the addition of a quantity of resin from the pine tree "Pinus Halepensis" during fermentation. Turpentine! Appellation Controlee!)
S.C. Best by ??? "To Drink Or Not Drink??" Your call! :)
Going out now get back to gardening!!
