The wine market value is largely associated to terroir, in some cases resulting in highly expensive wines that attract fraudulent practices. The existent wine traceability system has some limitations that can be overcome with the development of new technological approaches that can tackle this problem with several means. This review...
Wine fingerprinting using a bio-geochemical approach
Fernandes, José Ramiro; Pereira, Leonor; Jorge, Pedro; Moreira, Luís; Gonçalves, Helena; Coelho, Luís; Alexandre, Daniel; Eiras-Dias, José; Brazão, JoãoThe wine sector is a billion euro business and therefore subjected to multiple attempts of fraudulent practices. This requires the development of rapid and reliable methods to detect such situations. Several methodologies have been developed based on the chemical profiles of the wines, but they are limited due to the environmental conditions that cannot be controlled. The use of DNA-based detection systems are ...
Survey of yeast diversity during wine bottling processes using restriction anal...
Baleiras-Couto, Margarida; Gomes, A. S.; Casal, Margarida; Duarte, FilomenaBackground and Aims: Microbiological stability of bottled wine is largely dependent on the bottling process as the last technological operation. In this survey yeast contamination was monitored and characterized during wine bottling. Methods and Results: Samples of wine, apparatus surfaces and bottles were collected. Yeast counts were recorded and colony morphotypes differentiated. Isolates were characterized b...
