Ròuguì

• Type: Heavily oxidized oolong (dark oolong), usually with a strong degree of roasting.
• 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).
• 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.”
• Geographic coordinates: 27°43’ North latitude, 117°41’ East longitude.

2. History and Cultural Significance:

• 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).

• Name:

  • “Rou” (肉) - meat, fleshy. Some believe this word indicates the richness and density of the tea’s flavor. Others associate it with the reddish tint of the tea leaves.
  • “Gui” (桂) - cinnamon, cinnamon tree. Indicates the characteristic spicy aroma of the tea, reminiscent of cinnamon.

• 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.

3. Botanical Description and Raw Material:

• Cultivar: For Rougui production, the tea bush cultivar of the same name is used - Ròuguì (肉桂, ròu guì). This cultivar is distinguished by:
  • Medium-sized leaves: Rougui leaves are medium-sized, oval-shaped.
  • Dark green leaf color: The leaves have a rich dark green color.
  • Dense leaf texture: The leaf blade is dense, fleshy.
  • Pronounced aroma: The Rougui cultivar is distinguished by a strong, spicy aroma that manifests already at the bush growth stage.
• Harvest: Harvesting occurs in spring, usually in late April to early May.
• Harvest standard: Bud and two to three upper leaves are picked.
• Raw material requirements: High standards, only healthy, undamaged leaves are used.

4. Terroir and Cultivation Features:

• Wuyi Mountains: 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.
• Growing altitude: 500-1000 meters above sea level and higher.
• Soils: 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.”
• 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.
• “Zheng Yan” (正岩, Zhèng Yán): “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.
• “Ban Yan” (半岩, Bàn Yán): “Half-rock” - territory around “Zheng Yan,” where growing conditions are slightly less extreme, but still quite challenging.
• “Zhou Cha” (洲茶, Zhōu Chá): “Flatland tea” - tea grown on flat areas outside the reserve. Considered least valuable.

5. Production Technology:

Rougui production is a complex process requiring great skill. It includes both traditional stages of oolong tea making and features inherent to Wuyi oolongs, particularly prolonged charcoal roasting.

• Harvest (采摘 - cǎi zhāi): Described above.
• Withering (萎凋 - wěidiāo): Picked leaves are spread outdoors (sun or shade withering) or indoors for several hours. The withering process can be quite lengthy.
• Shaking (摇青 - yáo qīng): 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.”
• Oxidation (发酵 - fājiào): 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.
• Kill-green (杀青 - shā qīng): High-temperature pan-firing to stop the oxidation process.
• Rolling (揉捻 - róuniǎn): Leaves are shaped into longitudinally twisted strips.
• Drying (烘干 - hōnggān): Preliminary drying to remove moisture.
• Charcoal roasting (焙火 - bèihuǒ): 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.
• Sorting (分级 - fēnjí): Finished tea is sorted by size and quality.
• Rest: After roasting, tea “rests” for some time so that flavor and aroma balance.
• Re-roasting: Sometimes a second, lighter roasting is conducted.

6. Organoleptic Characteristics:

• 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.
• 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.
• 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.

7. Chemical Composition:

Rougui, like other Wuyi oolongs, is rich in:

• Polyphenols: High content of polyphenols, including catechins and theaflavins, thearubigins.
• Amino acids: Contains various amino acids, including L-theanine.
• Alkaloids: Caffeine, theobromine, theophylline.
• Essential oils: Rich in essential oils, especially cinnamaldehyde, eugenol, which determine the characteristic aroma.
• Vitamins: C, B group, E, K.
• Minerals: Potassium, fluorine, magnesium, manganese, iron, selenium.

8. Health Properties:

• Warming effect: Rougui has a pronounced warming effect, making it especially good in cold weather.
• Digestive improvement: Stimulates digestion, promotes food assimilation, especially fatty foods.
• Tonic effect: Invigorates, clarifies the mind, increases performance and concentration.
• Antioxidant action: Protects cells from free radical damage, slows aging processes.
• Cardiovascular system: May help reduce “bad” cholesterol levels, strengthen vessel walls, normalize blood pressure.
• Toxin elimination: Promotes body cleansing from waste and toxins.
• Mood elevation: Rougui is a tea that gives a feeling of warmth, comfort, and joy. It is often recommended for fatigue, stress, or depression.

9. Brewing:

• Water temperature: 90-95°C (boiling water is not recommended).

• 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.

• Process:

  1. Warming teaware: Rinse the gaiwan or teapot with boiling water to warm the vessel and prepare it for brewing.
  2. Tea rinse (quick rinse): Place tea in the gaiwan, pour a small amount of hot water and immediately drain the water. This stage allows washing dust from the leaves and “awakening” the tea, preparing it for unfolding.
  3. First brewing: Pour hot water (90-95°C) over the tea and steep for 1-3 minutes. The first brewing time can be short, about 30-60 seconds, especially if the tea is of good quality.
  4. Pour the liquor into cups: Completely drain the liquor from the gaiwan or teapot into a fairness cup (cháhǎi), then pour into cups. This is needed so that all cups receive liquor of the same strength.
  5. Subsequent brewings: Rougui can be brewed multiple times (5-7 times, sometimes more), gradually increasing steeping time by 30-60 seconds with each subsequent infusion. With each infusion, the tea’s taste and aroma will change, revealing new facets.

Important nuances:

• Don’t oversteep: Too long steeping can make the tea taste astringent and bitter.
• Listen to the tea: Follow your sensations and adjust brewing time depending on desired liquor strength.
• Observe the tea: 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.

10. Storage:

Rougui, especially heavily roasted specimens, is less demanding of storage conditions than green or lightly oxidized oolongs. Nevertheless, to preserve its rich taste and aroma, it is recommended to:

• Location: Store tea in a dry, dark, cool place without sharp temperature changes.
• Container: Use airtight containers, best suited are:
  • Ceramic or porcelain jars: They preserve tea aroma well and don’t affect its taste.
  • Clay jars: Also suitable, but ensure they have no foreign odors.
  • Metal (tin) cans: Acceptable, but ensure they are food-grade.
  • Dense paper bags: Suitable for short-term storage.
• Tea enemies: Avoid exposing tea to:
  • Direct sunlight: It destroys beneficial substances and deteriorates aroma.
  • Moisture: Tea can become damp and moldy.
  • Foreign odors: Tea easily absorbs odors, so store it separately from spices, coffee, fish, and other strongly scented products.

11. Price and Counterfeits:

Rougui is an expensive tea, especially if it originates from the protected “Zheng Yan” zone. Its price can vary within very wide limits, from several dozen dollars per 100 grams to several hundred dollars for the same weight, and sometimes much more, depending on:

• Origin: Tea from the protected “Zheng Yan” zone (“True Rock Core”) is valued much higher than “Ban Yan”

11. Price and Counterfeits (continued):

• Raw material quality: Whether select buds and young leaves are used or more mature raw material.
• Producer’s skill: The experience and reputation of the tea master who produced the tea significantly affects the price.
• Degree and quality of roasting: Complex, multi-stage charcoal roasting performed by an experienced master significantly increases tea cost.
• Tea age: Some connoisseurs prefer aged Rougui, which over time acquires new flavor and aroma nuances.
• Rarity: Some rare varieties or blends can be very expensive.
• Demand: High demand for Rougui also affects its price.

Due to high price and popularity of Rougui, unfortunately, many counterfeits and imitations are present in the market. How to avoid counterfeits:

• Buy only from verified sellers: 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.
• Beware of too low prices: Suspiciously low price is almost always a sure sign of counterfeit. Real Rougui cannot be cheap. Remember, miracles don’t happen.
• Carefully study appearance: 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.
• Evaluate aroma: 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.
• Check liquor and spent leaves: 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.
• Be especially careful when buying Rougui from “Zheng Yan”: Due to limited production volume and high demand, tea from this zone is most often counterfeited.

12. Interesting Facts:

• “Rougui - king of aromas, Shui Xian - king of taste”: This is what they say in China, emphasizing the main virtues of these two famous Wuyi oolongs.
• “Brew Rougui seven times, and the cinnamon aroma still won’t disappear”: This saying speaks of Rougui’s aroma persistence and its ability to withstand multiple brewings.
• Tea for cold weather: Thanks to its warming effect, Rougui is especially good in autumn and winter.

13. Comparison with Other Rock Oolongs:

• Dà Hóng Páo (大红袍, Dà Hóng Páo - Big Red Robe): 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.
• Shuǐ Xiān (水仙, Shuǐ Xiān - Water Narcissus): Another famous Wuyi oolong. Shui Xian usually has more pronounced floral and creamy notes in taste, while Rougui has spicy and “fiery” ones.
• Tiě Luóhàn (铁罗汉, Tiě Luóhàn - Iron Arhat): 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.

14. Rougui Varieties:

Depending on growing location, harvest time, processing technology, and roasting degree, several Rougui varieties exist:

• Zhèng Yán Ròuguì (正岩肉桂): Most valuable and expensive, originates from the protected “True Rock Core” zone. Has the most pronounced “rock” character (“yan yun”).
• Bàn Yán Ròuguì (半岩肉桂): Produced in the “Half-rock” zone surrounding “Zheng Yan.” Also valued, but considered slightly less refined.
• Zhōu Chá Ròuguì (洲茶肉桂): “Flatland” Rougui, grown on flat areas outside the reserve. Most affordable in price.
• Niú Lán Kēng Ròuguì (牛栏坑肉桂): “Cinnamon from the cow pen.” Very rare and expensive type, raw material for which is collected in the narrow Niu Lan Keng gorge in the “Zheng Yan” zone. It is believed that tea from this gorge has especially strong aroma and taste.
• Lǎo Ròuguì (老肉桂): Aged Rougui that has been stored for several years or even decades. Valued for deeper and more complex taste.
