Despite being the fastest-growing segment in the wine packaging industry, canned wine still faces challenges. It lacks the elegance associated with bottled wine and has not gained the same popularity as boxed wine. Additionally, there is an unfortunate issue with some canned wines occasionally emitting a less-than-desirable odor reminiscent of rotten eggs.
A recent study published in the American Journal of Enology and Viticulture (AJEV) revealed that the type of ultrathin plastic lining used inside aluminum cans can significantly enhance the aroma of the wine and prolong the lifespan of the container.
The collaboration between researchers began when winemakers sought help from Sacks after experiencing quality issues with canned wines, such as corrosion, leakage, and the unpleasant smell of rotten eggs. This led to an investigation into identifying the problematic compounds causing these issues and why they were specific to wines and not other beverages like sodas.
Sacks and Goddard joined forces, combining their expertise in flavor chemistry and packaging/material science. Through a series of experiments analyzing the chemical composition of commercial wines, they were able to pinpoint the causes of corrosion and off-putting aromas.
