The tea we used was loose leaf and I learned a lot about the different varieties, which include oolong, black, green, white and red. Oolong, black, green and white tea are all made from the same tree but they are oxidized for different lengths of time and have different levels of caffeine. Only 1 percent of all the tea made in the world is white tea, so it is by far the rarest. It's only made from the best tea leaves. Red tea is made from the Rooibos Tree which grows in South Africa. There is a whole culture around tea and it's one of the most wonderful and relaxing experiences for me. This winter when you curl up with a cup of hot tea, take a moment to savor the smell, feel the warmth on your face and relish the first sip! Daughter.
