The aromatic volatile composition of Lonicera edulis wines produced with three different strains of Saccharomyces cerevisiae

Abstract

Three different strains of Saccharomyces cerevisiae – D15, Dibosh and 71B – were evaluated in the fermentation of Lonicera edulis wines. Volatile aromatic components were analysed by gas chromatography–mass spectrometry coupled with headspace solid-phase microextraction. In all, 81 volatile compounds were identified in L. edulis wines, including 43, 48 and 38 individually found in wines fermented with D15, Dibosh and 71B. There were 17 common volatile aromatic components found in all the three L. edulis wines. The main volatile compounds in wines fermented with D15 and Dibosh yeasts were 2-methyl-1-butanol (24.8%) and hexane (20.6%). Pentanol was the primary volatile aromatic compound in wines produced with S. cerevisiae 71B, accounting for 40.8% of total volatile aromatic compounds. Combining the sensory analysis, S. cerevisiae D15 was suggested to be the most suitable strain for producing L. edulis wine. © 2018 The Institute of Brewing & Distilling.
