先將綠茶放入白水鍋中煮。茶水燒開之后,煮到茶水較濃時,用漏勺撈去茶葉之后,再繼續(xù)燒片刻,并邊煮邊用勺揚(yáng)茶水,待其有所濃縮之后,再加入適量鮮牛奶或奶粉,用勺揚(yáng)至茶乳交融,再次開鍋即成為馥郁芬芳的奶茶了。

茶葉的由來??
茶葉已經(jīng)發(fā)展成為“柴米油鹽醬醋茶”的人們生活日用品,更是我國少數(shù)民簇“寧停三日飯,不停一日茶”的生活必需品。唐代陸羽著的世界第一部茶葉專著《茶經(jīng)》是這樣記載:“茶之為飲,發(fā)乎神農(nóng)氏,聞于魯周公。。。。傍時浸俗,盛于周朝。”,茶葉作為藥用,記載最早是《神農(nóng)本草經(jīng)》:神農(nóng)嘗百草,日遇七十二毒,得茶而解之。 李時珍的《本草綱目》中記載:“茶苦而寒,最能降火,又兼解酒食之毒,使人神思矍爽,不昏不睡?!薄冻圆桊B(yǎng)生記》中記載有:“茶也,養(yǎng)生之仙藥,延年之妙術(shù)也。。?!?。東漢《桐君錄》中:“南方有瓜蘆木,亦似茗,至苦澀,取為屑茶飲,亦可通夜不眠,煮鹽人但資此飲?!?上層社會把茶作為飲料是從周武王以茶代酒開始。在《封氏聞見記》中:“開元太山有僧大興禪教,人人煮茶驅(qū)睡,致使人人相仿效,逐成風(fēng)俗。”到了漢代茶已成商品漢代王褒的《僮約》中:“烹茶盡具”,“武陽買茶”等記載了我國最早的茶葉市場。到了唐宋時期飲茶已經(jīng)普及到平民百姓,宋王安石云:茶之為用,等于米鹽,不可一日無。
茶葉開始作為飲料是摘鮮葉煮飲,到南北朝時開始把鮮葉加工成茶餅。后來唐代又創(chuàng)制了蒸青團(tuán)茶;宋代創(chuàng)制了蒸青散茶;明代創(chuàng)制了炒青綠茶、黃茶,黑茶、紅茶、花茶等;清代創(chuàng)制了白茶、烏龍茶等。
茶葉由我國的云、貴、川高原向全國傳播,古有“蜀地茶稱圣,蒙頂?shù)谝患摇钡恼f法。秦統(tǒng)一中國后,茶葉順長江而下傳遍半個中國,現(xiàn)我國有17省,900余縣產(chǎn)茶。又我國沿海傳向世界50個國家和地區(qū)。茶葉作為商品于1610年輸入歐洲,先是荷蘭、葡萄牙,1638年輸入英國。1664年輸入沙俄。17世紀(jì)輸入美洲,1674年輸入紐約。美國威廉.烏克斯著《茶葉全書》中說:“飲茶代酒之習(xí)慣,東西方同樣重視,唯東方飲茶之風(fēng)盛行數(shù)世紀(jì)之后歐洲人才始習(xí)飲之。”作為茶葉引種傳到世界各地,當(dāng)然是在唐宋以后的事,公元729引日本,828年傳朝鮮;1618年到俄國;1780到印度;1828年傳印尼,1834年斯里蘭卡;1914年馬來西亞,作為商品傳到這些國家當(dāng)然更早許多。
