回答1:

鉴别茶叶的优劣,可从茶叶的形状、色泽、香气、滋味、汤色等方面来判别。
 外形:主要从茶叶的条索、嫩度、色泽、净度几方面鉴别。

  条索:条形茶的外形叫条索。经紧细、圆直、匀齐、重实为好;

  嫩度:茶叶的嫩度主要看芽头多少、叶质老嫩和条索的光润度。此外,还要看峰苗(用嫩叶制成的细而有尖峰的条索)的比例。一般红茶以芽头多、有峰苗、叶质细嫩为好;绿茶的炒青以峰苗多、叶质细嫩、重实为好;烘青则以芽毫多、叶质细嫩为好。

  色泽:看茶叶的颜色和光泽。红茶的色泽有乌润、褐润和灰枯的不同;绿茶的色泽有嫩绿或翠绿、洋绿、青绿、青黄,以及光润和干枯的不同。红茶以乌润为好,绿茶以嫩绿、光润为好。

  净度:主要看茶叶中是否含梗、末或者其它非茶类的杂质,以无梗、末和杂质的为好。

  此外,还可以嗅嗅茶叶的香气是否正常,有无烟、焦、霉、馊、酸味或其它不正常的气味。内质审评包括评定香气、滋味、汤色和叶底。取一小撮茶叶,放入茶杯中,用开水冲泡,并盖上杯盖。5分钟后,打开杯盖,先嗅杯中香气,再看汤色、品尝滋味;

  最后看茶叶的嫩度、色泽和匀度。香气用嗅觉来审评香气是否纯正和持久。可反复多嗅几次,以辨别香气的高低,强弱和持久度,以及是否有烟、焦、霉味或其它异味。汤色茶叶内含物被开水冲泡出的汁液所呈现的色泽叫汤色。汤色有深浅、亮暗、清浊之分。以汤色明亮、纯净透明、无混杂的为好;汤色灰暗、混浊者为差。红茶以红艳明亮为优,绿茶以嫩绿色为上品。滋味茶叶经沸水冲泡后,大部分可溶性有效成分都进入茶汤,形成一定的滋味,滋味在茶汤温度降至50℃左右时为最好。品尝时,含少量茶汤,用舌头细细品味,从而辨别出滋味的浓淡、强弱、鲜爽、醇和或苦涩等。叶底观察杯中经冲泡后的茶叶的嫩度、色泽和匀度。还可以用手指去按压,去判断它的软硬、厚薄和老嫩程度。花茶的审评标准主要是香气和滋味。以花香鲜浓持久、滋味醇和鲜美、汤色叶底嫩绿明亮为好。

新茶与陈茶的鉴别主要是看它的色、香、味。

  色泽:茶叶在存过程中,主要受空气中氧气和光的作用,绿茶由新茶的青翠嫩绿逐渐变得枯灰。红茶由新茶的乌润变成灰褐。

  滋味:陈茶的滋味淡薄,同时茶叶的鲜爽味减弱而变得"滞钝"。

  香气:陈茶由于香气物质的氧化、缩合和缓慢挥发,使茶叶由清香变得低浊

  上述区别是对较多的茶叶品种而言的。当保存条件良好,这种差别就会相对缩小。至于有的茶保存后品质并未降低,那就另当别论了。

  识别茶叶的好坏可以从其外形、色泽、味道来评价,比如说绿茶干茶色泽为墨绿色或翠绿色,汤色黄绿明亮,香气是悦鼻的板栗香;乌龙茶外形一般是条形或颗粒状,汤色橙黄明亮,滋味醇厚鲜爽,带有自然的花香,德信乌龙单枞茶类,就能很好地体会到这些特征。红茶有碎茶和条形茶之分,红碎茶外形是匀度好,色泽黑褐油润,汤色红艳明亮,滋味浓强鲜,条形红茶在外形上是紧结显毫,汤色红艳明亮,滋味浓强鲜。这些特征都是好茶的几点特征

回答2:

可以看茶的年份,年份越长,茶的口感越好,茶是越陈越香的,但这前提还是想看茶的颜色,形状,香气来分

回答3:

学认茶叶好坏的入门:
第一(看)
茶叶的颜色,茶叶的形状
第2(闻)
茶叶的香味
第3(摸)
茶叶的叶面,(如果的普尔或者乌龙)就看他的茶叶包的紧还是松!
第4(品)
味道是自己品出来的,每个人口味不同,对茶看法不同
