・What is jumping?

Jumping is the upward and downward movement of tea leaves in a teapot when certain conditions are met. As a result, each piece of small tea leaves is evenly mixed with hot water, and black tea with perfect taste, color and aroma is extracted.

<Conditions required for jumping>

1. Make sure there is enough oxygen in the water
　　・Use tap water vigorously to absorb oxygen ・Shake mineral water before use ・Do not use water that has been boiled ・Do not boil too much
2. Hot water must be hot enough for convection to occur
　　・The best temperature is about 95℃ to 98℃, which is about to boil. ・Warm the teapot in advance.

<Situation of jumping>

1. When freshly boiled water is poured vigorously into a teapot containing tea leaves, the oxygen in the water becomes air bubbles and sticks to the tea leaves, and the force of the bubbles causes almost all of the tea leaves to gather on the surface of the water.

2. As time passes, the tea leaves slowly absorb moisture, become heavy, and sink in a snow-like motion.

3. The tea leaves, sinking under their own weight, begin to move up and down along with the convection of the hot water in the pot. This is jumping.

Four. Eventually all the tea leaves will sink to the bottom under the weight of the moisture.
