Eighty-six samples of wine of the vintages 1949-1983,made from the seven grape varieties of Koshu, Riesling, Chardonnay, Muscat Bailey A, Cabernet Sauvignon, Cabernet franc, and Pinot noir, were tested to find their concentrations of dimethyl sulphide (DMS) by the head space method of gas chromatography. DMS was found in Koshu wine by GC-MS analysis. DMS was formed during bottle aging, and the concentration of DMS increased as storage time increased, reaching a maximum concentration in wines aged 5-10 years, and gradually decreasing with further again. DMS in white wines aged one to two years was 0-trace, and 3.2-6.0 μg/l for red wines aged one yeat. The maximum concentrations of DMS in eight vintage wines tested were as follows : 7.6 and 14.9 μg/l in Koshu I aged 9 years and Koshu II aged 10 years, respectively; 20.1,22.2 and 34.0 μg/l in Riesling, Chardonnay, and Muscat Bailey A, aged 6 years; 68.4,63.9,and 19.8 μg/l in Cabernet Sauvignon, Cabernet franc, and Pinot noir aged 5 years. DMS in red wine forms earlier than in white wine, and reaches a higher concentration. The formation of DMS contributes to the bottle bouquet of white wines.
