Inyanja, inyanja, n'imbuto nibirango bisanzwe mubihugu byose bishyuha. Kuri Sri Lanka, iherereye mu nyanja y'Ubuhinde, nta gushidikanya ko icyayi cy'umukara ari kimwe mu birango byihariye.Imashini zitora icyayizirakenewe cyane mugace. Nka nkomoko yicyayi cyirabura cya Ceylon, kimwe mubyayi bine byingenzi byumukara kwisi, kuki Sri Lanka aricyayi cyiza cyumukara cyiza cyane cyane bitewe nubutaka bwihariye bwihariye hamwe nibiranga ikirere.

Ceylon yo gutera icyayi igarukira gusa mu misozi yo hagati no mu majyepfo yo mu majyepfo yigihugu. Igabanijwemo ibice birindwi by’umusaruro ukurikije imiterere y’ubuhinzi itandukanye, ikirere n’ubutaka. Ukurikije ubutumburuke butandukanye, igabanijwemo ibyiciro bitatu: icyayi cyo hejuru, icyayi cyo hagati nicyayi cyo hasi. Nubwo ubwoko bwose bwicyayi bufite imiterere itandukanye, ukurikije ubuziranenge, icyayi cyo murwego rwo hejuru kiracyari cyiza.

Icyayi cyo mu misozi ya Sri Lanka gikorerwa cyane cyane mu turere dutatu twa Uva, Dimbula na Nuwara Eliya. Ukurikije imiterere y'akarere, Uwo iherereye mu burasirazuba bw'imisozi miremire, ku butumburuke bwa metero 900 kugeza kuri 1600; Dimbula iherereye mu burengerazuba bw'imisozi miremire, kandi ubusitani bw'icyayi mu gice cy’umusaruro butangwa kuri metero 1100 kugeza kuri 1.600 hejuru y’inyanja; na Nuwara Eli Iherereye mu misozi yo muri Sri Lanka rwagati, ifite uburebure bwa metero 1868.

Ahantu henshi ho gutera icyayi cya Sri Lanka ni ahirengeye, naicyayiikemura ikibazo cyaho cyo gutoranya amababi yicyayi mugihe. Ni ukubera ko microclimate idasanzwe ya alpine muri utwo turere ikorerwa icyayi cyirabura cya Lanka. Imisozi irimo ibicu n'ibicu, kandi ikirere nubutaka nubushyuhe bwiyongera, bigatuma bigorana isukari ikozwe na fotosintezeza yibiti byicyayi nibibabi byegeranye, selile ntishobora kuboneka byoroshye, kandi ibiti byicyayi birashobora gukomeza kuba bishya kandi byiza. igihe kirekire bitaroroshye gusaza; hiyongereyeho, imisozi miremire Ishyamba riratoshye, kandi ibiti byicyayi byakira urumuri mugihe gito, ubukana buke, numucyo ukwirakwizwa. Ibi bifasha mu kongera ibiyigize birimo azote mu cyayi, nka chlorophyll, azote yose, hamwe na aside amine, kandi ibyo bigira ingaruka ku ibara, impumuro nziza, uburyohe, n'ubwuzu bw'icyayi. Nibyiza cyane kongera ubushyuhe; ubushyuhe bwa dogere selisiyusi 20 mu misozi miremire ya Sri Lanka ni ubushyuhe bukwiye bwo gukura icyayi; ibimera bya alpine ni byiza kandi hariho amashami menshi namababi yapfuye, bikora igicucu kinini cyo gupfuka hasi. Muri ubu buryo, ubutaka ntibworoshye gusa kandi bwubatswe neza, ahubwo nubutaka bukungahaye ku binyabuzima, butanga intungamubiri zikungahaye ku mikurire y’ibiti by icyayi. Birumvikana ko ibyiza byubutaka bwubutaka buhanamye bifasha amazi ntibishobora kwirengagizwa.

Byongeye kandi, ikirere cya Lanka gishyuha kiranga ikirere kigira uruhare rukomeye mugukoresha nyumaimashini zotsa icyayiguteka icyayi cyiza.Kubera no mu misozi miremire itanga icyayi, ntabwo icyayi cyose gifite ubuziranenge mubihe byose. Nubwo ibiti byicyayi bisaba imvura nyinshi kugirango ikure, byinshi ntibihagije. Kubwibyo, iyo imvura yo mu majyepfo y’iburengerazuba mu cyi izanye imyuka y’amazi iva mu nyanja y’Ubuhinde mu turere two mu burengerazuba bw’imisozi miremire, ni igihe Uwa, iherereye mu burasirazuba bw’imisozi miremire, itanga icyayi cyiza (Nyakanga-Nzeri); muburyo bunyuranye, iyo itumba rigeze, amazi ashyushye nubushuhe bwikigobe cya Bengaluru Iyo umwuka utemba ukunze gusura uturere twiburasirazuba bwimisozi twifashishije imvura y’amajyaruguru yuburasirazuba, bibaye igihe Dimbula na Nuwara Eliya batanga icyayi cyiza (Mutarama kugeza Werurwe).

Nyamara, icyayi cyiza nacyo kiva muburyo bwikoranabuhanga butanga umusaruro. Kuva gutora, kwerekana, fermentation hamweimashini isembura icyayiguteka, buri nzira igena ubwiza bwa nyuma bwicyayi cyirabura. Muri rusange, icyayi cyiza cya Ceylon cyiza gisaba igihe gikwiye, ahantu, hamwe nabantu bagomba kubyazwa umusaruro. Bose uko ari batatu ni ngombwa.
