Synthesis of noble white wines containing a high level of glycerin which are generally made of grapes infected with Botrytis cinerea was attempted; optimum conditions for glycerin fermentation by B. cinerea were examined in Koshu grape must. The best grape must suitable for noble white wine making, which contained a high level of glycerin and a little acetaldehyde, was obtained when raw grape must containing 15% of sugar at pH 3.0 was fermented with B. cinerea for 10 days at 15℃ in jar-fermenter with the aeration rate and stirring speed of 15 l/min and 200 rpm, respectively.The characteristic noble wine could be made from the grape must at the stationary stage of glycerin fermentation by B. cinerea : it contained a high level of glycerin and a little acetaldehyde and was evaluated as the best white wine by a sensory test.
