Most of the fuel on-board a rocket is used in the first few minutes of the mission to achieve an escape velocity of at least 25,000 mph (7 miles per second or 40,000 km/h)âthe speed a rocket must theoretically attain to escape Earth's gravity.
Traditionally Japanese green teas and spring teas are brewed at lower temperatures (160Â°F to 170Â°F) and standard Chinese green teas at higher temperatures (170Â°F to 180Â°F). Pre-warm the teapot or cup (optional): Pour a small amount of boiling water into the pot or cup. When the pot or cup is warm, pour out the water.
The overall flavor and sweetness of green tea is determined by a variety of amino acids and natural sugars. Bitterness and astringency are contributed by polyphenols (tannins). Amino acids dissolve at 140Â°F (60 Â°C) while tannins dissolve at 176Â°F (80Â°C).
