Research led by Gavin Sacks, Ph.D., and Julie Goddard, Ph.D., from the College of Agriculture and Life Sciences, alongside a team from Cornell University, has made significant strides in addressing the challenges of packaging wine in aluminum cans. Their studies, published in the American Journal of Enology and Viticulture, focus on the interaction between sulfur dioxide (SO2) and aluminum can liners, identifying the formation of hydrogen sulfide, which causes off aromas, as a key issue. By experimenting with the concentration of molecular SO2 and the type of ultrathin plastic coatings inside the cans, they found that maintaining SO2 levels at 0.4 ppm and using epoxy liners can significantly mitigate these undesirable effects. This research, awarded the 2024 Best Enology Paper by AJEV, aims to enhance the aroma and longevity of canned wines, making them a more attractive packaging option for consumers seeking convenience without sacrificing quality.

While it is the fastest growing sector of the wine-packaging market, canned wine faces a few hurdles. It's not considered as elegant as wine in a bottle, and it's not as popular as the formerly maligned "wine bag in a box." There is also the unfortunate fact—and there is no gentle way to put this—that canned wine occasionally smells like rotten eggs.A team led by Gavin Sacks, Ph.D. and Julie Goddard, Ph.D., both professors of food science in the College of Agriculture and Life Sciences, is working with wineries, manufacturers and New York state to eliminate that "off" aroma by ever-so-slightly altering the product's formulation and packaging, which is also prone to corrosion.In recent research published in the American Journal of Enology and Viticulture (AJEV), the team found that the choice of the ultrathin plastic coating inside aluminum cans can go a long way towards improving the aroma of the beverage and the lifespan of its container.The collaboration began several years ago, ...
