Re: When a sheng puer has matured, is it still a sheng cha?

I tried some expensive raw pu-er today and it was even lighter color than the picture in this site as I have linked it below. It would be difficult for me to accept it as the same kind of tea than the dark color, sweeter kind of pu-er that I have begun to like. If what is suggested here and in the articles by Leo is true, I wonder how the light color tea can turn into the kind of dark color tea, and how long it takes.
