Lovely tea, lovely flavour but sometimes it has a tendency to be over-powering or easily become bitter, however its cosy caramel and cinnamon palette can definitely be recommended. I would certainly sweeten this tea with something like honey or sugar, purely because its black base can be tart.
Don’t brew this tea for too long, 3-5 minutes and you should avoid the problems of an overly-potent black base and bitter-almond aftertaste.
