Abstract
Abstract Traditional alcoholic beverages produced from fermented grape pomaces ( Vitis vinifera L.) are very popular in Greece and many other Mediterranean countries and some times consumed in large amounts daily. Acetaldehyde and methanol are two important toxic volatile compounds in wine and alcoholic beverages, that formed during grape pomace fermentation. The EU regulation 1576/89 fixed common analytical composition limits for those volatiles (1000 g/hL AA for methanol and 73–500 g/hl AA for acetaldehyde. In this study the two major toxic volatile compounds, methanol and acetaldehyde, were determined in varietal grape pomace distillates. Twelve of the most p...
