Disclosed is a method for preparing a grape wine vinegar and a grape wine vinegar using the same, and more particularly a preparation method for grape wine vinegar and a grape wine vinegar using the same, which involves performing an alcoholic fermentation using grapes and yeast, followed by an aging process, and then introducing a vinegar starter into grape wine to cause an acetic fermentation, thereby creating a grape wine vinegar with improved taste and flavor and many health benefits due to high contents of organic acid and antioxidant components in addition to the ether component of grapes.

The present invention discloses a strain S. cerevisiae M 2016785 producing high concentration of -phenylethanol and application thereof, and belongs to the technical field of industrial microorganisms. The strain S. cerevisiae M 2016785 producing high concentration of -phenylethanol according to the present invention was deposited in China Center for Type Culture Collection (CCTCC) on Dec. 26, 2016 with the accession number OF CCTCC NO: M 2016785. The strain of the present invention has the high -phenylethanol production capacity, and is applied in the fermentation of Huangjiu, the fermentation of cooking wine, the brewing of vinegar, the fermentation of soybean sauce and the fermentation of Baijiu, in which the content of -phenylethanol can reach 410 mg/L, 450 mg/L, 300 mg/L, 200 mg/L, 110 mg/L and 370 mg/L respectively, and effectively increases the concentration of the flavor substance such as 2-phenylethyl acetate. The yeast strain of the present invention has good fermentation performance, obviously improves the -phenylethanol content in the fermented product, and improves the quality of the fermented product, and thus has broad application prospects.

A method for preparing an extract of herb(s) and/or spice(s) is obtained by infusion from a vinegar salt or from a slightly reacidified vinegar salt, used as extraction solvent. Additionally, the method described for preparing an extract of herb(s) and/or spice(s) concerns the obtaining of a concentrated extract of herb(s) and/or spice(s) having an increased flavor content while limiting loss of vinegar when preparing the same.
