I made my first mug of this with a moderately-heaped teaspoon but I may have left the water a little too long to cool (they recommend 80°). I brewed for three minutes. I was slightly surprised that the tea was still floating at the end. I could detect absolutely no aroma. To taste it had a touch of the basic tea flavour and a touch of butter and I didn’t really get anything else.
I made a second mug with the same tea and with the water a little hotter, again for three minutes. Again the tea was still floating at the end. I thought I detected a hint of roast beef in the aroma, but it wasn’t noticeably different to taste.
I made a third mug with the water perhaps a little hotter again. This time the tea sank to the bottom of the infuser immediately but I didn’t detect anything different about the flavour.
I made a second brew of this with rather more tea – a well-heaped teaspoon rather than moderately-heaped, but I couldn’t detect any differences.
I found this pleasant enough to drink, but with nothing memorable or impressive about it.
