Even though Malaysia isn't the biggest tea producer in Asia, its tea culture is quite impressive. Especially if you visit Cameron Highlands and try some teh tarik.
Teh tarik means pulled tea, which originates from the actual preparation process of this drink. Black tea is mixed with condensed milk several times, and the greater the distance between mixing vessels, the better teh tarik tastes! Pulled tea is extremely popular in Malaysia and Singapore. You can find lots of street vendors who try to attract tourists with their skills of pulling tea. Moreover, there are occasional competitions, where each tea maker tries to reach the furthest distance without spilling even a drop.
The Cameron Highlands region is considered the largest tea growing region, and is called the "Green Bowl" of Malaysia due to the various greenery cultivated there, including tea, roses, and strawberries. The Boh tea plantation is the biggest in Southeast Asia. The entire harvest from the plantation is processed at a nearby factory and can be tried right there.
The favorable climate of this region allows tea harvesting all year round. Thus, almost once per month after new shoots flush, workers start collecting tea leaves. But, if you want to see other attractions in the Cameron Highlands, you'd better plan your trip for February-March, when the rain is less strong and you can still see magnificent waterfalls and enjoy the foggy spirit of mossy forests. August-September is also great as the temperatures are moderate and some hiking can be done.
