In the 2009 (Table 3), spontaneous and inoculated acetifications
were performed.
However, the spontaneous fermentation stopped,
so we only obtained inoculated vinegars.
Regarding the effect of the type of container used in the acetification, the vinegar produced in glass vessel displayed the lowest values for all the parameters
studied.
These results were expected due to concentration
phenomena and compounds extraction in wood barrels.
The vinegar from cherry barrel had the highest AA, at levels significantly
different from the oak vinegar.
