Oak Solutions Group Announces New Research: Impact of Oak Tannin on Color Fixation and Stability
Oak Solutions Group has published new research outlining the advantages of using enological oak tannins to help fix and stabilize color in red wine.
Working in conjunction with Rodney Strong Vineyards and Enotrex, the Oak Solutions Group research team conducted an experiment on Pinot noir to evaluate the most effective treatment to benefit color fixation and stabilization during a commercial size trial.
“Our previous trials suggest oak tannin is able to help facilitate color fixation and stabilization by helping to promote bonding of anthocyanins with condensed tannins,” said David Llodrá, director of research and development. “Since we are specialized in oak, we wanted to understand the efficiency of our oak tannin and compare it to another commercial tannin product commonly sold for color fixation.”
Results from the study confirmed that oak tannins applied during maceration had a significant impact on color. Analyses also demonstrated that tr?/tan f² tannins had the highest impact on color fixation and stabilization when compared to another commercial tannin brand, even at lower dose rates.
