People ask all the time for Lipton tea and while they sell the bottled versions here, they don't actually sell the teabags. When I was in Holland a couple weeks ago, I saw the teabags for sale everywhere! So I don't understand why they don't sell them here.
Orange Pekoe and Ceylon are the commonly used teas in the states for making iced tea. And yes, these are black teas, just graded differently. It's about the size of the leaf. I have a brita filtered kettle that I use for everything and it does help a lot. I hate finding bits of limescale floating around in my glasses of water or in the bottom of the ice tea jug. While cooling is a big factor for the cloudiness of teas, so is not brewing it too strongly. Oh! the art of tea making! lol
