Provided is a method for producing a yeast extract that contains organic acids, in particular succinic acid at a high concentration and also contains glutamic acid at a high concentration. The production method comprises: an organic acid synthesis treatment step for maintaining a cultured yeast suspension under conditions effective to synthesize organic acids to thereby increase the organic acid content in the yeast； and a hot water extraction step for extracting a yeast extract from the yeast, which has been subjected to the organic acid synthesis treatment step, at 56
