In 2006, a team of Spanish scientists led by Maria Rosa Guasch-Jané developed a new method of identifying an acid left by compounds in red wine. The evidence was compiled using both liquid chromatography and mass spectrometry together, which revealed syringic acid in scrapings taken from jars in King Tutankhamun's tomb. Syringic acid is released by the breakdown of the compound malvidin, found in red wine.
