The term micronization usually refers to the reduction of average particle diameters to the micrometer range, but can also describe further reduction to the nanometer scale. Common applications include the production of active chemical ingredients, foodstuff ingredients, and pharmaceuticals.
BUT remember, the general rules still apply. Now, letâs quickly go through the most popular types of tea and their perfect steeping conditions. 1  Black tea: 0.5 teaspoon per cup; water temperature 96Â°C (205Â°F); steep for 3 minutes.  Green tea: 1 tsp/cup; temp. 65-80Â°C (150-175Â°F); 3-4 minutes.
How much caffeine is in oolong tea? The caffeine levels are similar in all types of tea and are dependent on steeping time. When steeped for 5 minutes, tea has about 50-70 mg of caffeine per cup of tea. Oolong tea is usually steeped for a much shorter time (less than a minute) so there is significantly less caffeine. In addition, oolong tea leaves can be brewed multiple times, and each time the caffeine levels decrease by about 75%. By the fourth infusion there is almost no caffeine left, but a good quality oolong tea will still have plenty of flavor. Back to Top
