When I look for a breakfast tea, I look for a distinct malty body (in this case, Assam), but with a suitable variety of estate and small and large leaf to provide a few different layers of flavor across the palate and a clean finish. MTW Irish Breakfast is perfect. The tea is strong, but consistently so, and it does not overpower. I brew it hot and steep it for a long time.
75% of my mornings are started with a visit to the tea cabinet and a reach for the MTW IB. (The rest is usually the MTW Scottish breakfast, which I save for when I want something a bit more malty and less ascorbic.)
Excellent way to start the day.
