There are three teas that I would literally cry about if they were ever discontinued. They are:
Churchill's Lady of the Earl
Churchill's Victorian Earl Grey
Lupicia USA's Seasonal Decaf Carol
Just about any other tea can be replaced by the same flavor in another brand, but those three are just too good. Y'all, go out and buy them so they keep making them and I don't have to cry.
I've tried all the Lady Greys and as far as I'm concerned this one takes the cake. The orange flavor is sharp and fresh and strong and the tea is high quality. It's hard to get decaf teas as good as Churchill's makes them. Simply the best.
