Is Chardonnay and Sauvignon allowed in Rioja ?

If we let the market(or would be Robert Parker ?) drive all in our lifes then DO don´t make sense to be continued exist.Tipicity for me mean culture of a people or region.It will be a pity if CS or SB of any place one day have the same taste,flavour,etc

We must take care about these issues....market,profit many times are opositive to tipicity
