We investigate black raspberry (Rubus occidentalis) wine made using traditional yeast (Saccharomyces cerevisiae A8, B6, GBY2, GBY3) and S. cerevisiae Fermivin (FM), which is widely used in wine manufacturing, and analyze the biogenic amine content and the volatile flavor compounds. Black raspberries were separately inoculated with yeast up to 1×109 CFU/kg, followed by incubation at 25°C for 7 days. FM produced the highest alcohol content, however the final fermentation characteristics of the wine made using four different yeasts were similar. S. cerevisiae A8 had a large biogenic amine (BA) content, specifically tryptamine, thus we excluded this yeast from fermentation. S. cerevisiae GBY3 was selected for black raspberry wine fermentation as a result of sensory evaluation. The volatile flavor compounds of two wines (S. cerevisiae GBY3 and FM) were analyzed by gas chromatography and mass spectrometry. 37 compounds in the samples were separated, and several ester compounds were identified in greater amounts in the wine made with S. cerevisiae GBY3 than in the wine made with FM. A greater amount of the major compound, ethyl benzoate, giving the sweet and fruity flavor, was identified in wine made with S. cerevisiae GBY3 than in the wine made with FM. In conclusion, S. cerevisiae GBY3 was confirmed to produce no major BAs and a better flavored wine. These results give new leads in the production of high quality wine.
