2000 Manzone Le Gramolere Bricat

Opened and decanted. .. after a couple of hours it was still quite tannic - a massive earthy rustic wine. Can't tell if there's enough potential for this one to around.
Finished the second half of the bottle a week later. It had mellowed a bit and was good with spinach and mushroom pizza. Fruit more evident, peaking out from the hugely structured backbone. Earthy cherry with hint of mint. Is this a Randy Dunn style Barolo that takes 25 years to come together?  
Manzone Barolos can require extended periods of cellaring since they are derived from vineyards fairly high in altitude. I have enjoyed 1999 vintage of Manzone Le Gramolere and Santo Stefano di Perno, both of which are more approachable and seem to have better balance (http://lestastevinsdulac.blogspot.com/2013/02/il-fascino-dei-vini-maturi.html )
