This is very british, but in a very delicate way. It is much lighter and delicate than most breakfast mixes. The official blurb compares its taste to roasted chestnuts – I would never have gotten there myself, but now I read it, it is a very good comparison. I had some teabags from a mixed Twinings box and this is the last, I am going to look for it, bagged (I am heretical, I do not mind that much, depending of course on age and circumstances) or loose.
I usually do not put sugar or milk (or anything dairy) on tea, but this is absolutely delicious with milk.
