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.
From the oak barrel, we obtained vinegar with the highest amount of total phenols and anthocyanins, but significant differences were not found with the
vinegar from cherry barrel.
These results were similar to those of Cerezo et al. (2008), who reported a generally decreasing trend of TPI and TA in vinegars acetified in cherry and oak barrels, being
slightly lower in oak.
