The concentrations of amyl alcohol, acesulfame, aspartame and caffeine were found to be below the quantitation limits of
the method in the investigated blackberry wines. Furthermore, the obtained data provide evidence that
the contents of methanol in blackberry wines were above the permissible limits, except for four conventional
blackberry wines. Thus, the concentrations of analyzed volatile substances measured in
blackberry wines necessitate more extended investigations of these volatile compounds in this popular
fruit wine.
