红茶与绿茶一样,都是用绿色的鲜嫩茶叶做成的,只不过加工方法有所不同。红茶是经过发酵做成的。人们把鲜茶叶揉捻,使细胞破裂,挤出汁液,然后发酵。发酵时,茶叶的叶绿素被破坏了——绿色消失,而它所含的鞣酸在氧化酶的作用下变成了红色的氧化物。这样就变成了“红茶”。

Black tea, like green tea, is made of green, fresh tea, but the processing methods are different. Black tea is made by fermentation. People knead the fresh tea leaves, rupture the cells, squeeze out the juice, and ferment it. When fermented, the chlorophyll of tea is destroyed - the green disappears, and the tannic acid it contains turns into a red oxide under the action of oxidase. This becomes “black tea.”
