American scientists have proven that you can tell a person by their choice of wine: lovers of sweet wine are more impulsive whereas lovers of dry are more open. Actually, it was a group of Australian and UK researchers - and they base their research on a sample of 45 healthy men and women from Sheffield in the UK. Here is the abstract of the article Sweet taste preference and personality traits using a white wine:
Understanding the influences of food and drink consumption patterns could help elucidate the factors that promote healthy dietary practices. Research has begun to investigate the influence of personality traits on dietary decisions. The current experiment measured personality traits and sweet taste preference using white wine in a healthy sample of adults (n = 45). Sweet taste preference was associated with a higher level of impulsiveness but lower openness. These traits have previously been suspected to influence dietary choices and are briefly discussed within this context.
As much as I would like to I cannot tell you much more about the study as the download costs US $ 31.50. If you fancy spending the money please do let me know if there is anything else of interest in the article. Until then I will be happy to oscillate between openness and impulsiveness - and hope for more academic research being made available free of charge.
