One portion of the strawberry puree was pressed to study the effect of two types of starting substrates (semi-solid and liquid) (Table 1). Six glass containers were filled with 6 L of fruit substrate (four purees and two liquids). Half of the containers of each type of substrate were inoculated with the yeast Saccharomyces cerevisiae QA23 at a concentration of 2 × 106 cells/ml, and spontaneous alcoholic fermentation was allowed to occur in the other half. All wines were spontaneously acetified keeping it in the same containers. Two final treatments were tested in vinegars: pasteurization or centrifugation. The average acetic degrees in the 2008 strawberry vinegars were 4.8
