兰花香桂花香铁观音香气来源

第一：是鲜叶中固有的。

目前铁观音鲜叶中已知的芳香成分将近50种。另外，由于地域、气候、土壤的不同，也会造就铁观音茶叶特殊的香气和滋味，即俗称的“地域香”，这也就是为什么好茶都讲究原产地的原因，但总体来说，这一部分占整个香气的比例较少。

其二，是其它物质在加工过程中经过酶促作用和热化学等反应转化而来，这是形成铁观音茶叶香气的主要部分，即俗称的“工艺香”。

现代制茶工艺在制茶力度上、温度上以及时间上的控制有了很大的提高和变化，比如铁观音工艺中最重要的做青，下图是摇青，目的是让鲜叶在摩擦作用下溢出茶汁促进氧化，也能促进芳香物质的形成

好的铁观音有馥郁的兰花香，随着工艺的提高，除了兰花香，也会有其他的香气，比如蜜香和桂花香等，但加香精完全是没必要的，香气是乌龙茶的最大特点之一，根本无需加香精，但不能排除一些不良茶商在陈茶或者劣质茶中添加香精。

要判断是否加香精，闻香基本可以判断，好的安溪铁观音香气纯正不杂无异味，闻着很舒服。

最后，铁观音以观音韵出名，讲究的是高雅幽长的兰花香，并不以香高为贵。

First: it is inherent in fresh leaves.

At present, there are nearly 50 known aromatic components in fresh leaves. In addition, due to different regions, climates, and soils, the special aroma and taste of tea will also be created, which is commonly known as "regional fragrance". The proportion of the whole aroma is less.

The second is that other substances are transformed through enzymatic and thermochemical reactions during the processing process. This is the main part of the aroma of tea, which is commonly known as "craft incense."

Modern tea-making technology has greatly improved and changed the control of tea-making strength, temperature and time. For example, the most important thing in the Tieguanyin process is to make green. The picture below is shaking green, the purpose is to make the fresh leaves rub. Under the action of overflowing tea juice to promote oxidation, it can also promote the formation of aromatic substances

Good Tieguanyin has a fragrant orchid fragrance. With the improvement of craftsmanship, in addition to orchid fragrance, there will also be other fragrances, such as honey and osmanthus fragrance, but it is completely unnecessary to add flavor. The fragrance is the biggest feature of oolong tea. One, there is no need to add flavors at all, but it cannot be ruled out that some unscrupulous tea merchants add flavors to aged tea or inferior tea.

To judge whether to add flavor, you can basically judge it by smelling the fragrance. The good Tieguanyin fragrance is pure and has no peculiar smell, and it smells very comfortable.

Finally, Tieguanyin is famous for the Guanyin rhyme, and it pays attention to the elegant and long orchid fragrance, not the high fragrance.
