What is High Mountain Tea?

High Mountain tea (Gao Shan Cha or Gaoshan in Chinese) is the name given to all semi-oxidized teas grown in the mountain ranges in central in Taiwan, particularly in tea gardens that are located above 800-1000 meters in altitude above sea level or higher.

Tea grown in these high altitudes benefits from higher humidity and rain but less sunlight and therefore it grows slowly. The sloping landscape also makes for harder tea farming conditions and low production.

The resulting tea is fleshy, juicy, and rich; filled with distinctive and bold floral aromas and flavors, and much higher quality than tea grown at lower altitudes.

The Origin of This Oolong Tea

High Mountain oolong tea plants were first brought over from mainland China to Taiwan during the 17th century by Chinese settlers that brought also their knowledge about producing high quality oolong teas.

Today these are considered by tea connoisseurs as some of the best oolong teas around. Although you may find them growing now in Thailand and Vietnam, quality is lower and so also much cheaper.

Producing High Mountain Tea

High Mountain tea is a semi-oxidized tea, usually to lower levels of oxidation: 12% to 15% and very lightly roasted, making this tea closer to a green tea than a black tea, but these levels may vary from tea garden to tea garden.

  • Harvesting: This oolong tea is typically made of complete stems that contain 3 to 4 leaves handpicked from the end of the branch. This fact also reduces the production yield from each bush, making these teas even rarer.

  • Withering: Once harvested, leaves are spread in sunlight to wither gaining wonderful floral aromas of rose or jasmine.

  • Rolling / Shaping: The tea is then shaken, rolled and folded to begin oxidation and to shape the leaves. This low oxidation level is enough to eliminate some of the harsher and grassier elements that you generally find in green teas.

  • Firing: Once shaped into pearls or strips, these teas are subjected to high temperatures, or firing, to stop the oxidation process. Tea leaves may still be roasted, but only slightly to enhance the floral flavor and aroma profile of tea.

The end result is an amazing tea with a great floral and naturally sweet flavor with a lingering aftertaste that will not let you forget this tea.

High Mountain Tea Varieties

High Mountain oolong tea or Gaoshan may vary according to the source, as the terroir may affect each tea in a unique way. The main mountainous regions are:

  • Ali Shan /Ali Mountain: the most common of all High Mountain teas; Alishan tea gardens are located at 1000m to 1500m in altitude. Check out more information about this particular tea here.

  • Ali Shan LuZhu and Shan Ling Xi: tea plantations are located at 1600m in altitude. These forested regions with rainfall the year-round produce teas with a clear taste and very little astringency.

  • Li Shan /Pear Mountain: tea gardens may be located at altitudes over 2000m. Great teas with fruity notes are produced due to the consistently cool temperatures at this altitude range.

  • Da Yun Ling Mountain: premium tea grows in altitudes over 2500m. Typical Da Yun Ling tea is a green oolong with minimal processing resulting in a sweet clean but distinct flavor.

This tea may also be categorized according to the time of harvest:

  • Spring harvest: takes place in June beginning the harvest year with a vigorous tea after the winter dormancy. This tea is more robust and a unique floral character.

  • Winter harvest: takes place in late October and ends the harvesting year with the final crop that yields a crisper and lighter tea.

Experience the Best of High Mountain Tea

Caffeine in High Mountain Tea

High Mountain tea is an oolong tea with caffeine, like all other oolongs and any other type of tea that comes from the tea bush. This tea contains a moderate level of caffeine.

Caffeine is affected by soil conditions, production process and oxidation level. However, this is mainly due to the fact that this tea is made up of the bud and 2 or 3 leaves on the same stem.

Since caffeine is mainly stored in young buds and top leaves as a means of protection against predatory insects, larger leaves down the stem contain less caffeine. Therefore a blend of young and old leaves reduces the total amount of caffeine per cup.

Caffeine has wonderful benefits, but also some drawbacks:

  • If you are sensitive to caffeine you may experience agitation, headaches, difficulty sleeping and in more severe cases even heart palpitations, insomnia and stomach problems.

  • If you are pregnant or breastfeeding, follow the advice of your doctor as to how much caffeine you may ingest per day.

Moderation may be important if caffeine affects you. Find the right balance for you and enjoy your tea earlier in the day if it affects your sleep.
