I had another go at this tea with a slightly shorter steep. Still no pumpkin flavour, sadly.
Basically it tastes like black tea flavoured with cloves and a few other spices hanging out in the background – which isn’t really bad persay (although the cloves are a touch on the acrid side) it’s just that I keep looking for pumpkin and being disapointed by not finding it. It’d make more sense if this tea were called something like “Autumn Spice” rather than give us false expectations.
I think this might be a good tea to have with milk so I’ll try it that way next time.
