A recent study by the American Chemical Society, conducted by the University of Florida, indicates that aluminum cans can maintain the chemistry and appearance of red muscadine wine as effectively as glass bottles during typical storage periods.
During the investigation, scientists compared the behavior of wine in standard glass bottles and aluminum cans, stored at both normal and elevated temperatures to simulate more extreme conditions, for six months. Pigments responsible for color, sulfite levels, and volatile compounds were analyzed.
The results showed that the concentration of anthocyanins, responsible for the red color, decreased similarly in both containers, with no perceptible changes for consumers. Other chemical markers also behaved consistently, and no reactions were detected between the wine and the can coating that could affect the flavor or safety.
Although the study did not include sensory tests, the chemical data suggest that packaging wine in cans does not pose a significant disadvantage for products intended for immediate or short-term consumption.
