French and American oak have their own characteristics. When they are processed together, they complement each other and create unique synergy. XtraMocha is an ideal blend of proportions combined with a special long and intense toast.
French oak brings better structure, length, also presenting more spicy and toasted aromas.
American oak creates better roundness and more sweet aromas (mocha, caramel, vanilla).
The blend has a higher CAOX than the 2 components alone. Wine fruitiness is enhanced.
