Tbunny,
The difference is possibly the Bergamont. Lady Grey has Seville orange and lemon with bergamont, and Earl Grey has Bergamont orange.
I would think the Earl grey is more noticable in the taste of Bergamont.
I have to say, when I do drink coffee it has to have milk and two sugars! Tell you what tho, coffee (Not tea, its awful!!
) made with all milk is gooooooooood, as is coffee with evaporated milk yum yum!
