/PRNewswire/ -- Natural cork remains the overwhelming choice for U.S. wine drinkers because it conveys higher quality than alternative closures, according to a recent survey by Tragon Corp., the Company announced today. According to the survey, 94 percent of respondents said they would be more likely to purchase wine with natural cork. A nearly equal number, 93 percent, said that natural cork conveys high or very high quality. "These results are remarkable because we rarely find such overwhelming agreement among consumers," said Rebecca Bleibaum, Tragon's Vice President, Sensory and Consumer Insights. "We consider 70 percent to be a powerful plurality, but 94 percent positive purchase interest is almost unheard of."
