People tend to serve white or Rose' wines too cold and red wines too warm. Pulling a white or Rose' straight from the refrigerator is way too cold. This wine will actually taste more acidic and nearly tasteless, but letting it warm up for about 20 minutes, all the fruit or true grape flavors come out.
So...the bottom line is 20 minutes...it takes about 20 minutes out of the frig for a white or Rose' wine to express its true flavors or 20 minutes in the frig for a red wine if it is too warm. Plain and simple...properly chilled wines do taste better.
