I only drink Earl Grey tea, but had to get Yorkshire tea in the local shop the other day, as they had no Earl Grey, But despite drinking Yorkshire tea years ago, this Yorkshire tea tasted not as good as I remembered, and seemed to have less tea in the sachets than before.
It might be that I am now so used to Earl Grey, and the slightly fragrant taste, that no other tea tastes right, I only drink tea black, no milk, so you get the flavours of tea better, and can judge what tea is which.
