Just discovered this in my cupboard. Although the tea is quite old – more than a year old, in fact – the tin was just good enough, and some of the original scent is still there. Gave it a really long, barbaric steep – something like 7 minutes – and ended up with a very nice cup. Don’t do that if you get Opium Hill fresh, though :)
(rating is for fresh tea, from memory – really powerful when re-steeped several times – has a characteristic cold orchid-like scent and flavor in later steepings)
