Penn State scientists devise a one-minute test that reveals why wines with similar tannins feel different

Scientists at Penn State University have created a quick test that solves a long-standing winemaking puzzle: why wines with similar tannin levels can taste completely different. The new method takes just one minute and could help winemakers better understand and control their wines' flavour profiles. It's a clever bit of research that bridges the gap between chemistry and what you actually experience when you take a sip.
