Try steeping the first infusion (1 tablespoon) for 30 seconds @ 190 degrees with the lid on. Then throw this infusion away – it can be a bit funky.
At this point the leaves should have unfurled and it should smell quite rank (I mean that in a good way!)
The next infusion go for 30 seconds more and it will taste pretty good.
The second infusion for 45 seconds gets much more complex, a hint of sweetness but very malty and smooth. If you like dark teas I think you will tend to like this more than others.
Very complex tea – you could experiment with brew times and the amount of leaves and spend a good few hours coming up with new flavor profiles. I come back to this one a lot.
