I dunno. I was trying a sample which had been sitting oxidizing for days (till i felt like trying it) from a tin opened maybe 2 years ago (?more?). It´s not a fair trial. Keep that in mind. But since there seems to be very little about this tea that i can find on google, here goes my 2 cents.
Official description mentions hazelnut and vanilla and citrus. I spotted the citrus, bergamot-ish indeed to my nose, vanilla yeah now that you mention it, but I did not get any hazelnut (old tea, remember. a fresh tin might be another matter). It seems like it has some Darjeeling on it. And it reminds me a bit (bergamot, vanilla) of Thé au Tibet. But it really is not fresh tea so it is unfair to compare.
