Ròuguì肉桂

Classification and Origin

Category: Famous Teas of China, one of the "Four Great Bushes" (四大名枞, Sì Dà Míng Cōng) of Wuyi Mountains (the other three: Da Hong Pao, Tie Luohan, and Bai Ji Guan).

Coordinates: 27°43' North latitude, 117°41' East longitude.

Origin: China, Fújiàn Province (福建, Fújiàn), Wǔyí Mountains (武夷山, Wǔyí Shān), Wuyishan City. The most prestigious tea is considered to be that grown in the protected zone "Zheng Yan" (正岩, Zhèng Yán) - "True Rock Core."

Type: Heavily oxidized oolong (dark oolong), usually with a strong degree of roasting.

Facts

This is what they say in China, emphasizing the main virtues of these two famous Wuyi oolongs.

This saying speaks of Rougui's aroma persistence and its ability to withstand multiple brewings.

Thanks to its warming effect, Rougui is especially good in autumn and winter.

Rougui pairs well with meat dishes, pastries, desserts, nuts.

History and Culture

Cultural Significance: Rougui is one of the pillars of Wuyi oolongs, embodying power and fire. It is highly valued for its bright, memorable aroma, rich flavor, and strong impact.

History: Rougui has a long history spanning several centuries. It is believed to have been known during the Ming dynasty (1368-1644), and gained widespread recognition during the Qing era (1644-1912).

Botany and Raw Material

Rougui leaves are medium-sized, oval-shaped.

The leaves have a rich dark green color.

The leaf blade is dense, fleshy.

The Rougui cultivar is distinguished by a strong, spicy aroma that manifests already at the bush growth stage.

Cultivar: For Rougui production, the tea bush cultivar of the same name is used - Ròuguì (肉桂, ròu guì). This cultivar is distinguished by:

Picking: Harvesting occurs in spring, usually in late April to early May.

Pluck Standard: Bud and two to three upper leaves are picked.

Raw Material: High standards, only healthy, undamaged leaves are used.

Terroir

Altitude: 500-1000 meters above sea level and higher.

Climate: Subtropical monsoon, with warm winters and hot summers. High humidity, abundant precipitation, frequent fogs that shelter tea bushes from scorching sun and promote the accumulation of aromatic substances in the leaves.

Soil: The calling card of Wuyi Mountains is its unique soils ("Zheng Yan" - soils of "True Rock Core"). Red soils, rich in minerals, with inclusions of sandstone and gravel. They drain well and give the tea a characteristic "mineral" taste called "yan yun" (岩韵, yányùn) - "rock rhyme" or "cliff melody."

A unique mountain massif composed of red sandstone, with a characteristic "cliff" landscape. Tea bushes grow in rock crevices, on small plots of land surrounded by mountain peaks, rivers, and waterfalls.

"True Rock Core" - the heart of the reserve, where the best, "canonical" Rougui is believed to be produced. These are narrow gorges with steep cliffs, where tea bushes grow in crevices, on small plots of land. Growing conditions here are most challenging, which, according to the Chinese, gives the tea special value.

"Half-rock" - territory around "Zheng Yan," where growing conditions are slightly less extreme, but still quite challenging.

"Flatland tea" - tea grown on flat areas outside the reserve. Considered least valuable.

Production

Described above.

Picked leaves are spread outdoors (sun or shade withering) or indoors for several hours. The withering process can be quite lengthy.

Leaves are gently shaken and stirred on bamboo trays to initiate the oxidation process. This stage is conducted several times with breaks for leaf "rest."

The oxidation process that occurs during shaking and leaf "rest." Rougui belongs to heavily oxidized oolongs, but the degree of oxidation can vary depending on the producer and specific tea batch.

High-temperature pan-firing to stop the oxidation process.

Leaves are shaped into longitudinally twisted strips.

Preliminary drying to remove moisture.

This is one of the key stages in Wuyi oolong production, including Rougui. Tea is slowly roasted over smoldering charcoal in special baskets. This process can last several hours or even days, with temperature and roasting time carefully controlled by the master. Charcoal roasting gives Rougui its characteristic "smoky" aroma and "fiery" taste, and also promotes its further maturation during storage. The degree of roasting can vary from light to strong.

Finished tea is sorted by size and quality.

After roasting, tea "rests" for some time so that flavor and aroma balance.

Sometimes a second, lighter roasting is conducted.

The Wuyishan tradition distinguishes three levels of roast, and from the same raw material they yield three different teas:

The technological scheme for cliff oolong is fixed in GB/T 18745-2006 "Product of geographical indication — Wuyi rock-essence tea" (§6.6) and in GB/T 35863-2018 "Technical specification for Oolong tea processing".

Wuyishan masters record the quality of cliff tea with the formula 岩韵 = 山场 × 品种 × 焙火 — terroir, cultivar and fire. The cultivar and fire are described in this article; what a specific terroir does with Rou Gui is analysed in the articles "Niu Rou (牛肉)", "Ma Rou (马肉)" and "Niu Rou and Ma Rou (牛肉马肉)".

Organoleptic Profile

Dry Leaf Appearance: Large, longitudinally twisted leaves, dark brown, almost black in color, with a reddish tint. Leaves are dense, strong, oily in appearance. Sometimes a light grayish coating can be noticed, which appears as a result of strong roasting.

Dry Leaf Aroma: Very strong, characteristic, spicy, with a pronounced cinnamon note, as well as "fire" (roasting) notes, woody, chocolate, fruity (dried fruits), and floral nuances.

Liquor Aroma: Rich, deep, enveloping, with dominant cinnamon note, roasting overtones, dried fruits, chocolate, caramel, spices.

Liquor Color: From dark amber to red-brown, cognac-like, transparent, clear, with an oily sheen. Liquor color depends on the degree of oxidation and roasting.

Spent Leaves: Whole, dense, elastic leaves of dark brown color with reddish tint, unfold during brewing.

Taste: Very rich, saturated, dense, oily, with light astringency and noble bitterness that quickly transitions into a long, sweet aftertaste. The bouquet clearly expresses cinnamon, spice, "fire" (roasting), woody, chocolate, fruity (prunes, dried apricots, raisins), nutty nuances. The characteristic "rock rhyme" ("yan yun") is present.

Chemical Composition

Alkaloids: Caffeine, theobromine, theophylline.

Amino Acids: Contains various amino acids, including L-theanine.

Health Notes

Rougui has a pronounced warming effect, making it especially good in cold weather.

Stimulates digestion, promotes food assimilation, especially fatty foods.

Invigorates, clarifies the mind, increases performance and concentration.

Protects cells from free radical damage, slows aging processes.

May help reduce "bad" cholesterol levels, strengthen vessel walls, normalize blood pressure.

Promotes body cleansing from waste and toxins.

Rougui is a tea that gives a feeling of warmth, comfort, and joy. It is often recommended for fatigue, stress, or depression.

Contraindications

The most valuable and expensive, it originates from the protected zone of "True Cliffs". It possesses the most pronounced "cliff" character ("yan yun").

Produced in the "Half-Cliffs" zone surrounding "Zheng Yan". Also prized, but considered slightly less refined.

"Island" Rou Gui, grown on flatland plots outside the protected area. The most affordable in price.

Aged Rou Gui, which has been stored for several years or even decades. Prized for its deeper and more complex taste.

within "Zheng Yan", the market distinguishes tea by specific shanchang and names it after the terroir, adding the character 肉 — an abbreviation of 肉桂. Thus the family emerged: 牛肉 (Niulankeng gorge) · 马肉 (Matouyan massif) · 猪肉 (Zhuke basin) · 猴肉 (Shuiliandong) · 羊肉 (Sanyangfeng) · 心头肉 (Tianxinyan) · 龙肉 (Jiulongke) · 虎肉 (Huxiaoyan). The system of nicknames itself and a comparison of its two main addresses — in the article "Niu Rou and Ma Rou (牛肉马肉)"; detailed breakdowns of the terroirs — in the articles "Niu Rou (牛肉)" and "Ma Rou (马肉)".

Brewing

Too long steeping can make the tea taste astringent and bitter.

Follow your sensations and adjust brewing time depending on desired liquor strength.

Pay attention to liquor color, aroma, tea leaf unfolding. This will help you better understand the tea's character and select the optimal brewing method.

Tea Amount: 5-7 grams per 150-200 ml of water.

Teaware: Gaiwan (traditional Chinese cup with lid) or Yixing clay teapot are ideal. Yixing clay is porous and "breathes" well, allowing the tea to fully unfold. Yixing clay teapots "accumulate" tea aroma, so they are recommended for use only with Wuyi oolongs.

Water Temperature: 95-100°C.

Storage

Container: Use airtight containers, best suited are:

Enemies: Avoid exposing tea to:

Store tea in a dry, dark, cool place without sharp temperature changes.

They preserve tea aroma well and don't affect its taste.

Also suitable, but ensure they have no foreign odors.

Acceptable, but ensure they are food-grade.

Suitable for short-term storage.

It destroys beneficial substances and deteriorates aroma.

Tea can become damp and moldy.

Tea easily absorbs odors, so store it separately from spices, coffee, fish, and other strongly scented products.

Comparison

Often compared with Rougui due to similar origin. Da Hong Pao typically has a more complex and multifaceted taste with a broader spectrum of notes, while Rougui stands out with its bright, dominant cinnamon aroma.

Another famous Wuyi oolong. Shui Xian usually has more pronounced floral and creamy notes in taste, while Rougui has spicy and "fiery" ones.

Also produced in Wuyi Mountains. Tie Luohan typically has a more powerful, astringent taste with pronounced mineral notes, while Rougui is sweeter and more aromatic.

Price and Authenticity

Whether select buds and young leaves are used or more mature raw material.

The experience and reputation of the tea master who produced the tea significantly affects the price.

Complex, multi-stage charcoal roasting performed by an experienced master significantly increases tea cost.

Some connoisseurs prefer aged Rougui, which over time acquires new flavor and aroma nuances.

Some rare varieties or blends can be very expensive.

High demand for Rougui also affects its price.

Look for specialized tea shops with good reputation that value their customers and can provide reliable information about tea origin, harvest year, producer. They should also guarantee its authenticity and quality.

Suspiciously low price is almost always a sure sign of counterfeit. Real Rougui cannot be cheap. Remember, miracles don't happen.

Pay attention to leaf shape, color, integrity. They should correspond to the description given above. Presence of many broken leaves, dust, foreign impurities - signs of low quality or counterfeit.

Dry tea should have a rich, complex aroma with characteristic cinnamon, roasting, dried fruit notes. Avoid tea with weak, unexpressive, musty, or foreign smell. Artificial flavoring, sometimes used by unscrupulous sellers, usually betrays itself with an overly sharp, unnatural smell.

Liquor color should be from dark amber to red-brown, transparent, with oily sheen. Spent leaves should consist of whole, elastic leaves of dark brown color.

Due to limited production volume and high demand, tea from this zone is most often counterfeited.
