不同季節(jié)產的茶應如何鑒別?如何選購茶葉包裝機?
茶樹在生長周期中,因為受到不同季節(jié)氣候變化的影響以及茶樹自身營養(yǎng)的消長狀況不一,從而使得采下來的鮮葉原料品質也產生一定的差異,由此加工而成的茶葉,其品質自然也不盡相同。茶人根據不同季節(jié)對茶葉的自然品質總結出一條廣為流傳的俗語:“春茶苦,夏茶澀,要好喝,秋白露”.這里的“秋白露”,指的是白露前后采摘的秋茶。
茶葉的季節(jié)鑒別主要從干看和濕看兩方面來分辨。只有將干看與濕看相結合,才能更準確地分辨出是何季茶。
干看主要從干茶的色、香、形三方面來分辨春茶、夏茶和秋茶。春茶的品質特征是綠茶色澤綠潤,紅茶色澤烏潤,茶葉肥壯重實,或有較多白毫,且無論綠茶、紅茶,條索狀的都十分緊結,珠茶顆粒圓緊,同時香氣馥郁。夏茶的品質特征是綠茶色澤灰暗,紅茶色澤紅潤,茶葉輕飄松寬,嫩梗寬長,且綠茶、紅茶條索松散,珠茶顆粒松泡,香氣稍帶粗老。秋茶的品質特征是綠茶色澤黃綠,紅茶色澤暗紅,茶葉大小不一,葉張輕薄瘦小,香氣較為平和。
此外,干看還可以結合偶爾夾雜在茶葉中的茶花、茶果來判斷該茶是何季茶。春茶的茶葉中偶爾會夾有茶樹幼果,其大小近似綠豆;夏茶的茶葉中幼果接近豌豆大?。磺锊璧牟枞~中茶果直徑可達0.6厘米,這些都是可以作為判斷茶葉為何季茶的方法。此外,如果是秋茶,茶葉中會偶爾雜有干茶樹花蕾或干茶樹花朵。
所謂濕看,就是對茶葉進行開湯審評,將所要判定的茶葉取出一小部分進行沖泡,通過茶葉的內質特征來作出進一步判斷。通常情況下,春榮沖泡的茶葉下沉速度較快,茶香濃烈持久,茶味醇厚,茶葉葉底柔軟厚實,正常芽葉較多。以紅茶、綠茶為例,作為春茶的紅茶湯色紅艷現金圈,而綠茶湯色綠中顯黃。夏茶茶葉沖泡后,下沉較慢,香氣稍低;綠茶滋味欠厚稍澀,湯色青綠,葉底中夾雜銅綠色芽葉。紅茶滋味較強欠爽,湯色紅暗,葉底較紅亮;茶葉葉底薄而較硬,對夾葉較多。而秋茶的茶葉經過沖泡后,往往香氣不高,滋味平淡,葉底夾有銅綠色芽葉,葉張大小不一,對夾葉較多。
