A portion of the puree from the 2009 strawberries was
concentrated by heating in awater bath at 80 C during 10 h, to test
another method of increasing the sugar content; the resulting
product was a cooked must (Table 1).
The sucrose final concentration was 140 g/L.
One litre of this substrate was fermented by a spontaneous process and 1 L was inoculated with the RP1 strain of
yeast.
The inoculated wines (IWs) were acetified with the same
acetic acid bacteria isolated in 2008, and the spontaneous wines
(SWs) were left to acetify spontaneously
