Isithombe: Amanzi aqhumayo e-Brewing Lab

Emoyeni othule welabhorethri, lapho isayensi nemisebenzi yezandla ihlangana khona, ingilazi ecwebezelayo ima phakathi nesikhashana esimisiwe ngesikhathi. Igcwaliswa ngamanzi acwebile, agwedlayo—iconsi ngalinye liphonseka emkhunjini ngomuzwa wenjongo, lidala ukunyakaza kwesiyaluyalu namandla adansela phezulu. Amabhamuza akhuphuka ngokuzungeza okuhle, abambe ukukhanya okuthambile, okuhlakazekile okuhluza egumbini, kuphinde kube ukubenyezela kwesiliva nokumhlophe. Ukucaca kwamanzi kuyamangaza, kucishe kube nokukhanya, njengokungathi kudistilled kuze kuphelele. Lokhu akuyona nje i-hydration-kuyisisekelo soguquko, umakhi othule ngemuva kwayo yonke i-brew enkulu.

Kuzungeze ingilazi uxhaxha olukhethiwe lwamathuluzi esayensi: amabhekha, ama-pipette, amaflask, namasilinda athweswe iziqu, ngalinye lihlelwe ngobunono endaweni yonke yokusebenza. Ukuba khona kwazo kuvusa umuzwa wokunemba kanye nenhloso, amathuluzi hhayi okokuqanjwa kodwa okwendalo ephathekayo. Ingilazi ngokwayo iphethe izimpawu zokulinganisa, ezicashile kodwa ezibalulekile, ezibonisa ukunemba okudingekayo kule nqubo. Ayigcwaliswa nje kuphela—iyalinganiswa, ilungiselelwe indima eyinkimbinkimbi kakhulu kunalokho okusikisela ukubukeka kwayo okulula. Amanzi angaphakathi awavamile; iyahlolwa, ilungiswe, futhi icwengisiswe ukuze kuhlangatshezwane nephrofayili yangempela yamaminerali edingekayo ekwenzeni ubhiya opholile, ohlanzekile we-pilsner malt.

Ukukhanyisa ekamelweni kufudumele futhi kwenziwa ngamabomu, kuveza izithunzi ezithambile futhi kukhanyisa ukwakheka kwe-glassware kanye noketshezi olungaphakathi. Igqamisa ukugoba kwengilazi, ukubenyezela kwamabhamuza, nama-ripples afiphele akha lapho amanzi ezinza. Ingemuva, elifiphazwe kancane, liveza uhlaka lwemishini eyengeziwe—mhlawumbe i-spectrometer, imitha ye-pH, noma isistimu yokuhlunga—okusikisela ukuthi lesi indawo lapho ikhemistri ihlangana khona nobuciko. Umkhathi unokuthula kodwa ukhokhiswe amandla, indawo lapho yonke into ibhalansile futhi zonke izenzo zenziwe ngamabomu.

Lesi sigcawu sithwebula ingqikithi yokuphisa ngokuyisisekelo. Ngaphambi kokuba okusanhlamvu kujule, ngaphambi kokuba kufakwe ama-hop, ngaphambi kokuba kuqale ukubila, kuba namanzi—ahlanzekile, alinganiselayo, naphilayo. Okuqukethwe kwayo kwamaminerali kuzobumba ukunambitheka, ukucaca, nokuzwakala komlomo komkhiqizo wokugcina. I-calcium, i-magnesium, i-sulfate, nama-bicarbonates kufanele kukalwe futhi kulungiswe ngokucophelela, ngoba athonya yonke into kusukela ekusebenzeni kwama-enzyme kuya empilweni yemvubelo. I-brewer, nakuba ingabonakali, ikhona kuyo yonke imininingwane: ekukhethweni kwe-glassware, ekuhleleni amathuluzi, ekugxilweni okuthulile okungena endaweni.

Kukhona ikhwalithi yokuzindla okwamanje, umuzwa wokuzola, ilukuluku elilawulwayo. Imema umbukeli ukuthi ame kancane futhi acabangele amandla angabonakali alolonga lokho esikunambithayo. Lesi sithombe akusona nje isifundo se-aesthetics—siwukuhlonipha indima eyisisekelo edlalwa amanzi ekukhiqizeni utshwala, nasekuhloleni okucatshangelwayo okuwuguqulayo usuke oketshezini olulula uwenze umphefumulo kabhiya. Kule labhorethri, yonke ibhamuza ixoxa indaba, futhi zonke izilinganiso ziyisinyathelo esibheke enkosini. Yindawo lapho isayensi iba ukunambitheka, futhi lapho ukuphishekela ukuphelela kuqala ngokuthululwa okukodwa, okucwebezelayo.
