From the post:
The aging process brings another fabulous aspect to this experience. Prime cachaças age in wood barrels made from over 26 different native Brazilian trees, giving them different body and characteristics. As even the most seasoned people around the world are only used to oak barrel-aged spirits, the discovery of these unexpected notes can intrigue even the most experienced connoisseur.
There are oak-aged cachaças that give you that familiar base taste you can get in any given whiskey, but try the ones aged in umburana, jequitibá, ipê, balsam wood, jatobá or guarandi and you’ll see that there is a wealth of tastes and experiences waiting to be untapped.
