Isithombe: I-Ale Fermentation eCarboy

Kulesi sigcawu esinemininingwane eminingi, umbukeli umenywa endaweni yesimanje yokwenza utshwala ehlanganisa ngaphandle komthungo ukusondelana kobuciko beqoqo elincane nokunemba kokukhiqizwa kwezimboni. Okubusa ngaphambili i-carboy yengilazi, izindonga zayo ezibonisa ngale ziveza uketshezi olugqamile olunombala we-amber phakathi nokuvutshelwa. Ubhiya ongaphakathi uyanyakaza—amabhamuza amahle akhuphuka esuka phansi, ageleze ekujuleni okusagolide njengemithambo ephuma amanzi. Phezulu, ungqimba oluwugqinsi lwe-krausen lunamagwebu futhi luyanyakaza, uphawu oluphawulekayo lwe-yeast metabolism esebenzayo. I-carboy imbozwe isivalo senjoloba esibomvu esnug, sibhobozwe isikhiya somoya esimise okuka-S esigobela phezulu kancane, amagumbi ayo abonisa ngale agcwaliswe uketshezi ukuvumela isikhutha ukubaleka ngenkathi kugcina ukungcola okuphuma emoyeni kude. Le divayisi elula kodwa enhle ikhuluma nebhalansi ethambile edingekayo ekuvubeleni: inqubo eqinile futhi esengozini, lapho isayensi yezinto eziphilayo ihlangana nekhemistri emdansweni woguquko.

Kwesokunxele se-carboy, i-scoop yensimbi engagqwali ihlezi phezu kwendwangu egoqwe kahle, igoqa ingxenye yemvubelo eyomile yokwenza utshwala. Izinhlamvana ziphaphathekile futhi zenziwe ngendlela ehlukile, ebonisa amandla awo amile—alungele ukuphila lapho ethulwa kushukela. Lo mniningwane omncane uvusa imvelo yesiko lokuphisa, lapho isithako ngasinye silinganiswa ngokucophelela nangenhloso. Ngakolunye uhlangothi, ibhodlela likabhiya eliyingilazi elinsundu lime liqondile, indawo yalo ibamba ukukhanya okuzungezile. Nakuba ingenalutho, iphakamisa indawo yokugcina yotshwala, isithembiso esithulile salokho okuzayo uma ukuvutshelwa sekuqediwe futhi ubhiya usufakwe esimweni, ufakwe ebhodleleni, futhi ujabulele.

Ngemuva, isigameko sinwebeka endaweni yezimboni ezengeziwe. Umugqa wezinsimbi ezicwebezelayo ze-conical fermenters ziklelisa odongeni, izindawo zazo ezipholishiwe zikhombisa ukuthambile, ngisho nokukhanya okugcwalisa isikhala. Lezi zitsha, eziphakeme futhi ezilinganayo, zifakwe ama-valve, amageji, nezivalo eziqinisiwe—amathuluzi okulawula nokungaguquguquki enqubweni engase ibe yinto engalindelekile njengoba ivuza. Ngaphezulu naseduze kwazo, inethiwekhi yabaphisi botshwala ibhobhoza izinyoka esikhaleni, amathangi axhumayo namaphaneli okulawula kuwebhu yokusebenza. Amaphaneli okulawula ngokwawo agcwele izinkinobho nezibani zenkomba, okuphakamisa izinga eliphezulu lokuzenzakalelayo nokuqapha. Nokho naphezu kobuchwepheshe obuyinkimbinkimbi, indawo igcina umuzwa wokufudumala nokuthinta komuntu. Ukukhanyisa kuthambile, akuwenzi ithunzi elibi, futhi izindawo ezingaphezulu zihlanzeke ngendlela emsulwa, okubonisa inhlonipho ejulile ngomsebenzi wezandla namasiko awo.

Sekukonke, isithombe sithwebula isikhashana esimisiwe phakathi kwesayensi nobuciko, phakathi kwezithako ezingavuthiwe nomkhiqizo osuphelile. Kungumkhosi wokuvutshelwa—hhayi nje njengenqubo yamakhemikhali, kodwa njengomkhuba wamasiko, ocwile emlandweni nasekusungulweni okusha. Kungakhathaliseki ukuthi ibukwa umpetha wotshwala ongumakadebona noma umshisekeli onelukuluku lokwazi, lesi sigameko simema ukuzindla ngohambo lukabhiya kusuka kokusanhlamvu kuya engilazini, kanye nomlingo othulile owembuleka kuyo yonke isitsha esibhabhizayo.
