To decant or not, part one

Here is the same wine before, and after decanting, and teher is differences, not always possitive.....

2006 Felettig Chambolle-Musigny;
Bright ruby, red berries, vanilla and leafy notes mixed with spices. Good acidity, tannic grip, not all of them ripe, some green and herbal notes again, ok length. 84

After two hours and 45 min in decanter, left in a cool room (15 degrees C)
Strawberry jam, spices and cinamon, still brutal tannins and raw, but more nuanced, not necessarily better.... 85
