2. Mbiri ndi Tanthauzo la Chikhalidwe:

• Mbiri: Mwambo wa tiyi ku Rucheng uli ndi zaka zikwi zambiri. Chiyambi cha Rǔchéng Báimáochá chitha kutsatiridwa kuyambira nthawi ya Mzera wa Song (宋, Sòng, 960–1279), pamene anthu am’derali anayamba kutola ndi kumwa tiyi wakuthengo wokhala ndi mphukira yaubweya ndi masamba aakulu. M’nthawi ya Ming (明, Míng, 1368–1644) ndi Qing (清, Qīng, 1644–1912), tiyi woyera waubweya wochokera ku Rucheng ankaperekedwa ku nyumba yachifumu monga gongcha (贡茶, gòngchá). Kafukufuku wasayansi wadongosolo wa gululi unayamba kumapeto kwa zaka za m’ma 1970: Lin Mufang (林睦芳) anafufuza makhalidwe a kakulidwe kachilengedwe, ndipo Chen Xingyan (陈兴琰) ndi anzake anatsimikiza malo a chisinthiko ndi ubale wa zipangizo za tiyi imeneyi. Mu 1983, m’nthawi ya kulimbikitsa kulima kwakukulu, katswiri wamaphunziro apamwamba Yuan Longping (袁隆平, Yuán Lóngpíng) anapita ku chigawochi ndipo anayamikira kwambiri khalidwe la tiyi ndipo analemba mawu akuti “Bai Hao Han Xiang” (白毫含香, Báiháo hánxiāng, “Ubweya woyera umasunga fungo labwino”). Mu 1987, Komiti Yotsimikizira Zokolola zaulimi ya Chigawo cha Hunan (湖南省农作物品种审定委员会) inavomereza mwapadera Rǔchéng Báimáochá ngati mtundu wa chigawo. M’zaka za m’ma 1990, pamene msika wa tiyi unatsika, makampaniwa anafooka, koma kuyambira koyambirira kwa zaka za m’ma 2010 anayambiranso mothandizidwa ndi boma la chigawo ndi kutsogoleredwa wasayansi ndi katswiri wa tiyi Liu Zhonghua (刘仲华, Liú Zhōnghuá) wa pa Yunivesite ya Zaulimi ya Hunan. Mpaka pano, mizere 56 yapitilira yasankhidwa, ndipo mankhwala atatu aakulu apangidwa: tiyi wofiira woswekasweka (红碎茶), Bai Mao Jian (白毛尖) ndi Bai Hao Yin Zhen (白毫银针).
• Dzina:
  • 汝城 (Rǔchéng) — chigawo cha Rucheng, dera la kum’mwera kwa Hunan pamene mapiri a Luoxiao (罗霄山脉, Luóxiāo shānmài) ndi Nanling (南岭山脉, Nánlǐng shānmài) amakumana.
  • 白毛 (báimáo) — “ubweya woyera / ubweya”. Amasonyeza chizindikiro chachikulu choonekera ndi chokhudza — ubweya woyera wochuluka pa mphukira ndi masamba aang’ono mbali zonse.
  • 茶 (chá) — tiyi.
• Tanthauzo la chikhalidwe: Rǔchéng Báimáochá ndi chizindikiro cha “chigawo cha tiyi cha zaka chikwi” (千年古县). Tiyi ameneyu wakhazikika m’makhalidwe a nyengo ya m’mapiri a kum’mwera kwa Hunan; masamba obiriwira oyambirira masika amawonedwa ngati mphatso ya chilengedwe ndi chizindikiro cha chilengedwe choyera. Mu mwambi wam’derali, tiyi amatchedwa “mapiritsi obiriwira a moyo wosafa, ngale pakati pa tiyi” (绿色仙丹，茶中明珠, lǜsè xiāndān, chá zhōng míngzhū). Mu 2023, ku Rucheng kunachitika chikondwerero choyamba cha China cha chikhalidwe cha tiyi wa ubweya woyera.

• Kutalika kwa mitengo ina yakuthengo ya Rǔchéng Báimáochá kumafika mamita 6, ndipo kukula kwa tsamba lalikulu kwambiri lomwe linalembedwa ndi 27.8 × 11.1 cm. Izi ndi kupitirira kwambiri miyeso yodziwika ya “chitsamba cha tiyi” ndipo zikuyandikira miyeso ya mitengo ya ku Yunnan.
• Kuchokera ku zipangizo zomwezo, mungapeze mitundu itatu yosiyana kwenikweni: wobiriwira, woyera ndi wofiira — zinthu zabwino kwambiri zophunzirira poyesera kuyerekezera.
• Katswiri wamaphunziro apamwamba Yuan Longping, yemwe amadziwika padziko lonse monga “bambo wa mpunga wosakanizidwa”, anasindikiza mawu olembedwa pamanja “白毫含香” (“Ubweya woyera umasunga fungo”) a Rǔchéng Báimáochá — ulemu wapadera kwa tiyi wa m’chigawo.
• Kutalika kwa kuchuluka kwa ma polyphenols mu gululi (kuchokera ~20% mpaka ~43%) ndi chimodzi mwazikulu kwambiri pakati pa zipangizo za tiyi zolembedwa ku China, zomwe zimasonyeza kusiyanasiyana kwakukulu kwa ma genetic a gulu lakuthengo.
• Pamene akuphika Rǔchéng Báimáochá wobiriwira, mphukira zimagwedeza molunjika m’madzi — chiwonetsero chotchedwa ndi olima tiyi am’deralo “ballet wa m’madzi” (水中芭蕾).

13. Mitundu ya Rǔchéng Báimáochá:

• Tiyi wobiriwira (Bai Mao Jian, 白毛尖, Báimáojiān): Ndiye malonda ochuluka kwambiri. Tiyi wothinana, waubweya; kukhala bwino kowonekera, mawu audzu-maluwa; kukoma kwa amino acid pang’ono. Wabwino kumwa tsiku ndi tsiku.
• Tiyi woyera (Bai Hao Yin Zhen, 白毫银针, Báiháo Yínzhēn): Amapangidwa kuchokera ku mphukira zosankhidwa; kukonza kochepa. Maonekedwe ake ndi “masingano” okhuthala asiliva, okhazikika ndi ubweya. Fungo ndi pichesi wamadzi ndi orchid. Kukoma ndi kofewa kwambiri, “kotsekemera ngati kirimu”, kokhala ndi kukoma kwakutha kwanthawi yayitali. Kuthekera kwa kukalamba kwa zaka zambiri.
• Tiyi wofiira (红碎茶, hóng suì chá, ndi wofiira wa masamba): Nsonga zagolide, fungo lamphamvu la uchi ndi zipatso, chakumwa chotsekemera chothinana chamtundu wofiira wa amber. Kuchuluka kwa theaflavins ndi thearubigins kumapangitsa tiyi ameneŵa kukhala wapadera pa “kukongola” ndi “moyo” — amamuyamikira kwambiri pokonza zosakaniza.

Pomaliza:

Rǔchéng Báimáochá ndi amodzi mwa tiyi omwe amatikumbutsa kuti chuma chosangalatsa kwambiri cha dziko la tiyi ku China sichimabisa m’mashelefu a masitolo apamwamba, koma mu chifunga cha nkhalango za m’mapiri, kumene alendo sapita. Gulu lapadera lakuthengo lomwe linadutsa njira ya zaka chikwi, kuchokera ku tiyi wa m’nkhalango wa magulu a m’mapiri kufika ku chinthu chokhala ndi chizindikiro cha malo — ndipo nthawi yomweyo likusunga kusiyanasiyana kwa ma genetic ndi umunthu “wam’munda”. Mitundu itatu ya kukonza — wobiriwira, woyera, wofiira — imatulukira mbali zitatu za chuma chimodzi cha botanical: kutsitsimuka ndi ukhondo, kukoma ngati silika, kuya kwa uchi. Kwa okonda, iyi ndi mwayi wosawerengeka kumvetsetsa momwe tsamba lomwelo, lokonzedwa ndi manja osiyanasiyana, limakhalira tiyi atatu osiyana kwenikweni — ndipo mu aliyense kuzindikira khalidwe limodzi la “ubweya” la mapiri akumwera kwa Hunan.
