Goldschläger is a Swiss cinnamon schnapps (43.5% alcohol by volume or 87 proof; originally it was 53.5% alcohol or 107 proof), a liqueur with very thin, yet visible flakes of gold floating in it. The actual amount of gold has been measured at approximately 13 mg in a 1-Litre bottle of Goldschläger. As of July 2016 this amounts to €0.55 EUR or lower on the international gold market.
Goldschläger was produced in Switzerland until the 1990s, when the brand was acquired by Diageo, which continued production of Goldschläger schnapps in Italy. Since 2008 it is a brand of Global Brands and produced in Switzerland again. The German word Goldschläger (" gold beater") designates the profession of gold leaf makers, who beat bars of gold into micrometre-thin sheets.
