Earl Grey - Why is it so popular?

Ever since I was a little boy I can remember Earl Grey tea, yes, growing up with a European family might have had a bit of an effect, but even the non-euros new about Earl Grey tea. Why is it so popular? There is no real answer to that, but I think that Earl Grey has a lot of similar parallels to Grey Poupon. Yes, there are hundreds of types of Dijon mustard, but again, the one name seems to stick out. Perhaps it is because both of these are somewhat more exotic than standard fare. In the case of Earl Grey, yes, it's a black tea, but it has a little bit of an exotic edge to it. It has bergamot oil in it (a member of the citrus family) and this unique smell and flavour not only give the Earl Grey a unique taste, but allow it to be distinctive yet not to different. Bergamot oil is not used for much other than tea, so this makes it rare yet relatively common(if the two can conincide for the same product). This seems to be part of the recipe for famous products; being different and unique, but not so much so that you lose your popularity. So, in my opinion, bergamot oil is what makes Earl Grey so popular.

- I only write for as long as it takes to steep my tea in the morning, so that's all for now.
