Of all the Earl Grey's I've tried, this and Rishi's version are the most robust.  If you like the distinctive flavor of bergamont, but wish it were more pronounced than in the conventional blend, and your not opposed to some extra tannins, then this or Rishi are your Earl Greys of choice.  Of the conventional Earl Grey teas that are relatively easy to find, my favorite is Bigelow's. My favorite Earl Grey is made by Revolution, and includes lavender as an ingredient. However, I have to knock Revolution by trying cut costs by not including a string with their tea bags. If you want to try an Earl with a unique citrus zing, go for Stash Double Bergamont. I think it includes grapefruit flavoring (just my perception). Lady Grey by Twinings also tastes great, and includes small blue flowers, which you can see in the loose leaf version. Cool visual effect against the dark black tea leaves.
