eimay is correct. Irish Breakfast is a darker, more stout tea than its cousin, English which tends to be smoother and more refined. I prefer Irish... and Twinings makes a great Irish and English (as many others have pointed out.) PG Tips is one of my favorites for iced tea. It is Great Britain's Lipton, only way better! And, the triangle bags (which they have had for decades are cute...important when brewing tea...lol)
