There’s more to wine grape stems than tannin. Researchers at the Laboratoire Excell biochemistry lab in Floirac, France have discovered they contain the salicylate family of molecules and Astilbin, which is shedding more light on how the inclusion of stems during fermentation impacts wine beyond the contribution of tannins.
Among our many activities, wine professionals devote a considerable amount of time to perception, the state of being where we become aware of something through the senses.
In the course of developing software for predicting consumer wine preferences, a Houston-based start up, VineSleuth, shed new light on the abilities of expert wine tasters and the validity of blind tasting assessments. Contrary to popular belief, the company’s VineSleuth metrics, which are based on the work of Chief Science Officer Michael Tompkins and his team, reveal that tasters can consistently identify aroma and flavor characteristics in blind wine evaluations. “We have extensive experimental data which support that expert evaluators have the capacity to precisely identify wine characteristics in blind repeat samples,” said Tompkins whose work spans thirteen years in the field of numerical methods. “During the course of our experiments, our vetted evaluators repeat sample characteristics about 90% of the time,” he says. VineSleuth’s data directly confronts the popular misconception that consistent sensory evaluation of wine is a random occurrence. In developing an algorithm designed to help consumers make wine selections based on personal preference, the company has established a benchmark based on the results of its top-performing tasters (including this author) and intends …
When wine professionals encounter a sensory deviation in wine and the offending molecule isn’t obvious, cork often takes the blame by default.
In 2013, a hemp strain known as Charlotte’s Web drew national attention to the therapeutic benefits of cannabidiol (CBD), especially for children suffering from health issues that make them prone to seizures. Developed by six siblings known as “the Stanley Brothers”—the founders of Colorado-based CW Hemp—Charlotte’s Web represents one of hundreds of commercial CBD products now sold throughout the U.S. that contain THC levels of less than 0.3 percent. The efficacy of Charlotte’s Web and similar hemp strains paved the way for Epidiolex, a hemp-derived CBD solution approved by the U.S. Food and Drug Administration (FDA) June 25. Developed by London-based GW Pharmaceuticals to treat patients as young as 2 who suffer seizures caused by two rare epileptic syndromes, Epidiolex is referred to by the federal government as “Cannabidiol Oral Solution” (CBD-OS) and could be legally available as soon as this fall. Historically, hemp has played an important role as a utilitarian plant; widely deemed a “superfood” today, it’s also consumed as a nutritional supplement. Once the regulatory floodgates are opened, consumer adoption of hemp-derived …
When it comes to wine storage, old habits are hard to break. But Dr. Paulo Lopes, Research and Development Manager at Amorim Cork, advises that if temperature and humidity are maintained at the correct levels, wine can be stored upright with no ill effects. In fact, sparkling wine should always be stored upright: a little-known fact that seems lost on many wine experts. During the course of his groundbreaking research, Lopes has seen no difference in the amount of oxygen found in wines that have been stored horizontally or vertically. Using science to debunk the myths that persist within wine culture is liberating largely because the facts can be even more compelling than the misleading maxims. In his recent presentation at the San Francisco Wine School on the reductive and oxidative nature of wine, Lopes made it abundantly clear that, after bottling, the main source of oxygen in wine comes from the cork itself. Atmospheric oxygen doesn’t make its way through the cork (neither does mold, for that matter); rather, the air trapped in cork’s …
Brandon Staglin, recipient of the Mental Health Association’s 2017 Clifford W. Beers Award, has been recognized as the nation’s leading consumer advocate for improving treatment and attitudes toward people who live with mental health conditions. Having recovered from schizophrenia, an illness that affects two million people living in the United States, Staglin is both a role model and an inspiration. He is the Board Director for the One Mind Institute, a non-profit dedicated to funding brain health research founded by Shari and Garen Staglin in 1995, and Director of Marketing and Communications for the Staglin Family Vineyard. In the below interview he talks candidly about his work and life experiences. What would you say to someone who has a family or community member who has been diagnosed with schizophrenia to help them understand that it’s possible to manage and overcome the disorder? Managing schizophrenia can be a challenge, but one that I have been able to meet and succeed at. One of the most helpful things I’ve done toward returning to wellness has been to …
