1、看三七花來源

三七生長的地(di)域性(xing)很強，文山特(te)殊獨有(you)的氣候(hou)、地(di)理環境才(cai)(cai)適合三七生長，所以只(zhi)有(you)文山的三七花才(cai)(cai)是比較好(hao)的，所以在網上購(gou)買時要(yao)看清楚，選擇文山三七花，從(cong)文山當地(di)發貨的商家(jia)。

2，選擇三年或四年的三七花

指此株三(san)七(qi)栽種(zhong)了幾年(nian)(nian)(nian)后采的(de)花(hua)(hua)就稱幾年(nian)(nian)(nian)的(de)三(san)七(qi)花(hua)(hua)，三(san)七(qi)種(zhong)植了三(san)年(nian)(nian)(nian)采收的(de)花(hua)(hua)稱為(wei)三(san)年(nian)(nian)(nian)花(hua)(hua)；三(san)七(qi)種(zhong)植四年(nian)(nian)(nian)采收的(de)花(hua)(hua)稱為(wei)四年(nian)(nian)(nian)花(hua)(hua)。市場上以三(san)年(nian)(nian)(nian)和四年(nian)(nian)(nian)的(de)三(san)七(qi)花(hua)(hua)為(wei)主，其中(zhong)四年(nian)(nian)(nian)三(san)七(qi)花(hua)(hua)質量更好，含(han)皂苷量更高，效果好。

3、看三七花外形

質量(liang)(liang)好(hao)的三(san)(san)七(qi)花(hua)(hua)(hua)花(hua)(hua)(hua)朵大小年(nian)(nian)(nian)份(fen)越(yue)(yue)長的，花(hua)(hua)(hua)朵較大，小花(hua)(hua)(hua)數量(liang)(liang)多，顏色鮮綠越(yue)(yue)緊實越(yue)(yue)好(hao)，三(san)(san)七(qi)花(hua)(hua)(hua)花(hua)(hua)(hua)朵要緊實、圓團，說明有皂苷效含(han)量(liang)(liang)高，質量(liang)(liang)等級就越(yue)(yue)好(hao)。相對來說，三(san)(san)年(nian)(nian)(nian)花(hua)(hua)(hua)花(hua)(hua)(hua)朵小，沒有四年(nian)(nian)(nian)花(hua)(hua)(hua)花(hua)(hua)(hua)朵大，三(san)(san)年(nian)(nian)(nian)三(san)(san)七(qi)花(hua)(hua)(hua)顏色要比四年(nian)(nian)(nian)三(san)(san)七(qi)花(hua)(hua)(hua)更綠，感覺(jue)很嫩(nen)，四年(nian)(nian)(nian)三(san)(san)七(qi)花(hua)(hua)(hua)偏(pian)黃。

4、看三七花顏色

優質三七(qi)花泡(pao)水(shui)后呈現(xian)(xian)淺綠色，無雜質沉淀(dian)，湯色透亮，花朵顏色呈現(xian)(xian)嫩綠色，花穗慢慢散開。質量差的(de)三七(qi)花泡(pao)水(shui)后呈現(xian)(xian)黃(huang)綠色，會(hui)有一些沉淀(dian)物(wu)，甚至會(hui)有泥沙沉積。

5、看三七花干度

三七(qi)花(hua)越(yue)干越(yue)好(hao)，干度(du)直接影響(xiang)三七(qi)花(hua)的(de)貯藏效果(guo)和價(jia)格，干度(du)好(hao)的(de)三七(qi)花(hua)置一朵于手中，沒有粘性(xing)的(de)感覺(jue)，能(neng)完全(quan)搓細。干度(du)不高的(de)三七(qi)花(hua)顯得濕軟，不干脆。

6、看三七花柄

選不(bu)(bu)(bu)帶花(hua)(hua)(hua)柄(bing)(bing)(bing)(bing)或者花(hua)(hua)(hua)柄(bing)(bing)(bing)(bing)短的(de)三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)，花(hua)(hua)(hua)柄(bing)(bing)(bing)(bing)不(bu)(bu)(bu)帶柄(bing)(bing)(bing)(bing)三(san)(san)(san)年(nian)(nian)(nian)(nian)三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)特(te)級(ji)、不(bu)(bu)(bu)帶柄(bing)(bing)(bing)(bing)三(san)(san)(san)年(nian)(nian)(nian)(nian)三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)一級(ji)、不(bu)(bu)(bu)帶柄(bing)(bing)(bing)(bing)三(san)(san)(san)年(nian)(nian)(nian)(nian)三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)中級(ji)、帶柄(bing)(bing)(bing)(bing)三(san)(san)(san)年(nian)(nian)(nian)(nian)三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)。四年(nian)(nian)(nian)(nian)云南三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)花(hua)(hua)(hua)柄(bing)(bing)(bing)(bing)比(bi)三(san)(san)(san)年(nian)(nian)(nian)(nian)花(hua)(hua)(hua)更(geng)短更(geng)粗，三(san)(san)(san)年(nian)(nian)(nian)(nian)花(hua)(hua)(hua)的(de)花(hua)(hua)(hua)柄(bing)(bing)(bing)(bing)會(hui)比(bi)四年(nian)(nian)(nian)(nian)花(hua)(hua)(hua)嫩一些。質量差(cha)的(de)三(san)(san)(san)七(qi)(qi)(qi)花(hua)(hua)(hua)花(hua)(hua)(hua)柄(bing)(bing)(bing)(bing)長、花(hua)(hua)(hua)型不(bu)(bu)(bu)均(jun)勻很(hen)雜亂，色澤也暗淡。

5、聞三七花味道

味甘苦四年花味道比三年花味道更(geng)濃(nong)，可以(yi)沖泡的(de)時間會更(geng)久
