Even more unappealing are the changes to the way interest paid on Series EE bonds is calculated. For bonds purchased starting on May 1, 2005, the variable rate was eliminated and interest changed to a fixed flat rate for the life of the bond -- or for the first 20 years of a 30 year bond.
Oolong tea is a traditional Chinese tea. Itâs made from the leaves of the Camellia sinensis plant, the same plant used to make green tea and black tea. The difference is in how the tea is processed. All tea leaves contain certain enzymes, which produce a chemical reaction called oxidation. Oxidation is what turns the green tea leaves into a deep black color.
Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties. The degree of oxidation can range from 8 to 85%, depending on the variety and production style.olong is especially popular with tea connoisseurs of south China and Chinese expatriates in Southeast Asia, as is the Fujian preparation process known as the Gongfu tea ceremony.
