I don't decant unless it's from a producer I know makes big tannic wines. Alot of times I'll buy 3 to six bottles of something and I can't help myself so I try one young. Then I will decant. Dunn Howell Mountain for example. I had one of my 2003 bordeaux futures, a Moulin Haut Laroque that actually was a fruit bomb with a big nose that became more tannic and closed after it was opened for an hour.
