Most of microelements play a big role in the biochemical processes running in the alcoholic drinks, at that their concentration is limited due to their toxic nature. Copper hold a specific place among microelements widely spread in the alcoholic drinks. Our goal was the mastering in the atomic-absorption methods and equipment for copper determination in the Georgian wines; comparison of the mentioned method with extraction photometric and addition methods of copper determination.
