Ikhofi, isiphuzo esigcwele amasiko futhi esifana nemikhuba yasekuseni emhlabeni wonke, siqukethe umdanso oyinkimbinkimbi wamakhemikhali nesiko. Iqala ohambweni lwezinzwa, inkomishi ngayinye inesithembiso sokuhlangenwe nakho kokubili okusekelwe kusayensi futhi kuphakanyiswe ubuciko.
Ingena endabeni yokusetshenziswa kwekhofi, izibalo zembula ukuxhumana okujulile phakathi kwabantu nomthamo wabo wansuku zonke we-caffeine. Ucwaningo olwenziwe yiNational Coffee Association lukhombisa ukuthi abantu abadala baseMelika abangaphezu kuka-60% badla ikhofi nsuku zonke, okuwubufakazi bendawo yalo ehlanganisiwe ezimpilweni zethu.
Ukuyenga kwekhofi kudlula umkhuba nje; isekelwe ku-flavour eyinkimbinkimbi namaphunga atholakala enqubweni yokuthosa. Ukugazinga ubhontshisi wekhofi kuqala uguquko lwamakhemikhali, lapho izinhlanganisela ezinjengama-lipids nama-carbohydrates zithola i-pyrolysis, okunomthelela kumaphrofayili ahlukile wokunambitheka athandwa ochwepheshe. Njengoba izinga lokushisa likhuphuka, i-Maillard reaction iyangena, isinika lokho kunambitheka okucebile, okusemhlabeni esikulinda ngokulangazela kukho konke ukuphuzwa.
Ngaphezu kwalokho, ukugcwala kwe-caffeine, emi cishe ku-1.2% kubhontshisi wekhofi amaningi, kudlala indima ebalulekile emphumeleni ovuselelayo wekhofi. Isakhiwo se-caffeine silingisa i-adenosine, i-neurotransmitter engavimbeli, ngaleyo ndlela yehlise ukukhathala futhi ikhulise ukuqapha. Lesi senzo somlingo we-biochemical yingakho nje abaningi behlobanisa ikhofi nokuthuthuka kokukhiqiza nokugxila.
Ekuphishekeleni ikhofi eliphelele, isisetshenziswa umuntu asisebenzisayo sinomthelela omkhulu ekugcineni. Imishini yesimanje yekhofi, efakwe ubuchwepheshe obuphambili, inikeza ukulawula okungenakuqhathaniswa okuguquguqukayo okufana nezinga lokushisa lamanzi, ukucindezela, nesikhathi sokuwakhipha. Isibonelo, imishini ye-espresso iklanyelwe ukuletha isithombe esinembile ngokugcina izinga lokushisa kwamanzi phakathi kuka-195°F kuya ku-205°F (90°C kuya ku-96°C) nokusebenzisa ingcindezi phakathi kwebanga le-9 kuya ku-10 emkhathini. Lawa mapharamitha alinganiswa ngokucophelela ukuze kukhishwe ukunambitheka okulungile endaweni yekhofi kuyilapho kuncishiswa ukubaba.
Ngaphezu kwalokho, ukuthuthuka kobuchwepheshe bokwenza utshwala kuholele ezicini ezifana nezigaya ezakhelwe ngaphakathi zokuqinisekisa ukuthi ikhofi lisha, ama-milk frothers azenzakalelayo ukuze kuzuzwe ukwakheka kwe-velvety, kanye nokuxhumeka kwe-Bluetooth kwezilungiselelo ozenza ngokwezifiso kusuka ku-smartphone yakho. Ukuhlanganiswa kwalezi zici akugcini nje ngokuqondisa inqubo yokupheka kodwa futhi kuvumela ikhwalithi engaguquguquki egculisa ulwanga ngisho nama-aficionados ekhofi aqaphela kakhulu.
Kulabo abalungele ukuphakamisa isiko labo lekhofi, ukutshala imali emshinini wekhofi wezinga eliphezulu akusaseyona into ewubukhazikhazi kodwa kuyisidingo. Ivala igebe phakathi kokunemba kwesayensi kanye nobuchule bokudla, ikuvumela ukuthi udale kabusha okuhlangenwe nakho kwekhefi ngaphakathi kokunethezeka kwekhaya lakho. Ngokucindezela inkinobho, ungakwazi ukuguqula ikhishi lakho libe yindawo engcwele yenjabulo yemizwa, lapho inkomishi ngayinye yekhofi ixoxa indaba yobuciko obucophelelayo nokuzinikela okungantengantengi ekwenzeni okuhle.
Ngakho-ke, noma ngabe uyi-barista enolwazi noma u-novice ofuna ukuqalisa uhambo lokunqamula umhlaba wekhofi, khumbula, ithuluzi elilungile lingenza umehluko. Zitholele injabulo yokwenza inkomishi ephelele, futhi uvumele ubuciko beukwenza ikhofithola indawo yakho efanele ekuphileni kwakho kwansuku zonke.
