Jancis has always been one of the voices and people in the wine writing biz that I've held in the highest esteem. She always shoots straight, never ducks a tough question and has no fear of going out on a limb and cares less about being controversial.
I agree the more people giving their opinions the better. It only serves to make people more informed and also balance out those who's reviews/scores seem excessively high or low. And I loved the comment about how good a value Douro white wines are...couldn't agree more!
