铁观音于民国八年自福建安溪引进木栅区试种，分「红心铁观音」及「青心铁观音」两种，主要产区在文山期树属横张型，枝干粗硬，叶较稀松，芽少叶厚，产量不高，但制包种茶品质高，产期较青心乌龙晚。其树形稍，叶呈椭圆形，叶厚肉多。叶片平坦展开，适宜制种铁观音茶。
安溪铁观音名称由来
清雍正年间，安溪西坪上尧茶农魏饮品佳茗。为乌龙茶之极品。其条索紧结，呈金黄色，俗称蜻蜓头，叶青蛙腿。开汤后，汤色金黄浓艳似琥珀，有天然馥郁的兰花香，滋味醇厚甘鲜，回甘悠久，俗称有“音韵”。铁观音茶香高而持久，可谓“七泡有余香”。

铁观音的保存
1、生石灰贮存法：选用干燥、封闭的陶瓷坛，放置在干燥、阴凉处，将茶叶用薄牛皮纸包好，扎紧，分层环排于坛的四周，再把灰袋放于茶包中间，装满后密封坛口，灰袋最好每隔1～2个月换一次，这样可使茶叶久存而不变质。
2、木炭贮存法：取木炭1公斤装入小布袋内，放入瓦坛或小口铁箱的底部，然后将包装好的茶叶分层排列其上，直至装满，再密封坛口，装木炭的布袋一般每月应换装一次。
3、暖水瓶贮存法：将铁观音茶叶装进新买的暖水瓶中，然后用白蜡封口并裹以胶布。此法最适用于家庭保管茶叶。
4、化学贮存法：用较厚的塑料袋，将除氧剂固定在一个角上，然后封好茶叶袋，除氧剂在一二天内能将铁观音茶叶的氧气吸收掉，实现除氧封存，效果很好。
