Innovative oenological products and techniques constantly need to be optimized in order to
produce high quality wines that are able to fulfill the demanding consumers, with a pleasant colour,
astringency, bitterness and a balanced organoleptic profile. New mesoporous materials with viability and
environmental safety characteristics, might be a feasible alternative to the use of bentonite, while nowadays
in the winemaking there is a major challenge caused by wastes derivate mainly from wine clarification
stages. This study was aimed at investigating the influence of conventional (bentonite and activated coal)
and alternative (MCM-41, SBA-15, KIT-6) fining agents on enological parameters, colour, as well as on
the antioxidant activity of a Cabernet Sauvignon wines. Our results show that mesoporous materials, KIT-6
and SBA-15 (6 g/L) present the highest reduction on antioxidant activity with 23.08% and 24.41%, while
bentonite and activated coal (1.5 g/L) reduced with 20.72%, respectively 33.18%. Cluster analysis performed
with the values of antioxidant activity differentiated wines treated with activated carbon from other wines.
