Lasers, nanoparticles and wine: white wine identification with SERS

By Alois Bonifacio
Wine counterfeiting is a concerning problem. Several strategies were developed to solve this problem. In this post is described the application of label-free SERS spectroscopy as an analytical technique for white wine characterization. This approach was tested in 180 samples of three white wines varieties from northeastern Italy. The results of this study show that SERS could be a good method to identify wine. Find out more

Musical wine glasses

By Bruno Mesz, Juan Cruz Amusategui and Sebastián Tedesco

Recently several studies were carried out to analyze the influence of music and sound on food or drink evaluation. Result show that sound has a perceptual impact on taste intensity and other qualities such as bitterness or sweetness. This post reports the use of an equipment, augmented glass, developed for displaying sound and taste stimuli, with applications in research on crossmodal taste-sound interactions, multisensory experiences and performances,
entertainment and health.

Irrigation for modulating Godello wine composition under humid conditions

By José Manuel Mirás-Avalos, Yolanda Bouzas-Cid, Emiliano Trigo-Córdoba, Ignacio Orriols and Elena Falqué

In many viticulture regions the need of vineyard irrigation has been discussed. Before this practice could be implemented is necessary to carry out research to evaluate the effects in wine quality. This post reports the results of a study that assessed the amino acid profile of musts and wines, volatile composition and sensory profile of wines from Vitis vinifera (L.) cultivar Godello under rain-fed and two drip irrigation systems over three consecutive years. The authors concluded that weather conditions affected more must and wine composition than in-season effects caused by irrigation.
