Researchers from Sonoma State University have found that consumers change their wine preferences as they age.
In a survey of 422 people, it was concluded that those people who agreed their preferences have change said they liked sweeter wines in their youth but graduated to drier red wines as they get older. However, those who said their preferences did not change always like sweet or semi-sweet wines.
The researchers concluded that wine producers should always have a sweet wine in their portfolios but that dry red and white wines prevail over time.
There aren't a lot of surprises here. I never did like sweeter wines, but I have found my palate changing from the bolder wines like barolo and barberesco to the softer red wines like pinot noir. I've always like cabernet sauvignon and Rhone Valley. I've been returning to chardonnay as I age too.
