First chemical and sensory characterization of Moribel and Tinto Fragoso wines using HPLC‐DAD‐ESI‐MS/MS, GC‐MS, and Napping® techniques: comparison with Tempranillo

Abstract

BACKGROUND: Due to the current dominance of a few grape varieties in the wine market, the aim of this work was to study the detailed phenolic and volatile composition, chromatic characteristics, and sensorial properties of red wines elaborated with new Vitis vinifera grapes (Moribel and Tinto Fragoso) identified using the High Perfomance Liquid Chromatography-Diode Array Detector-Electrospray Ionization-Tandem Mass Spectrometry (HPLC-DAD-ESI-MS/MS), Gas Chromatography-Mass Spectrometry (GC-MS), CIELab color space, and Napping ® techniques.RESULTS: Tinto Fragoso wine showed higher phenolic content than Moribel, with more anthocyanins, flavonols, and stilbenes. These wines also contained anthocyanin diglucosides not reported for Vitis vinifera wines. The odor activity values of free volatile compounds were calculated to indicate their influence on wine aroma, the fruity aromas of Moribel standing out particularly. The wines studied were positively evaluated by the tasters. Moribel's sensory profile was characterized by red fruit aromas and Tinto Fragoso showed more aromatic intensity and persistence in the mouth. CONCLUSION:The results obtained from the first characterization of red wines made from novel Vitis vinifera grapes suggest that Moribel and Tinto Fragoso could be appropriate raw materials for the elaboration of quality young red wines. Tinto Fragoso provided wines with sensorial properties different from those of Tempranillo, and could be an alternative to the well known red wines on the market.

Resurgence of minority and autochthonous grapevine varieties in South America: a review of their oenological potential

“…In contrast to the general trend of producing wine from globally disseminated grapevine varieties, associated with the French paradigm, there is a slight tendency to increase the number of studies of minority or autochthonous grapevine varieties. The aim is to seek distinct products, different from the current homogenized wine production . Despite the above, there are few studies that evaluate the oenological potential of these varieties and most of them focus on regions with an excellent winemaking tradition such as Aragón, Galicia, La Rioja, and La Mancha (Spain), including other countries such as Georgia and Azerbaijan that seek to maintain and provide products linked to the territory with different organoleptic characteristics .…”

Methods for evaluating the color of wines. The review

“…Модель CIELab позволила исследовать колориметрические изменения сусла и виноматериалов на разных этапах производственного цикла, установить влияние различных технологических приемов (брожение, настаивание мезги, выдержка), микроорганизмов (дрожжи, молочнокислые бактерии), вспомогательных материалов на качество красных вин, а также оценить перспективность новых сортов винограда и роль региона произрастания винограда [62][63][64][65]. Установлена корреляционная зависимость между значением параметров цвета и содержанием фенольных веществ в вине [66].…”

“…Установлена корреляционная зависимость между значением параметров цвета и содержанием фенольных веществ в вине [66]. Методами регрессионного анализа получены уравнения, позволяющие рассчитывать координаты цвета L*, a* и b* на основе показателей Y. Glories и значений оптической плотности 420, 520, 620 нм [63].…”
