Isithombe: I-Pitching Yeast in Brewing Process

Isithombe sithwebula umzuzu osondelene futhi onembayo enqubweni yokuphisa: isenzo sokufaka imvubelo. Isithombe sifakwe kuhlaka ngombono oseduze, sidonsela ukunaka kombukeli esandleni sowenza isiphuzo njengoba sithela ngokucophelela umfudlana wemvubelo eyomile ephuma esakeni elisiliva iyifaka ebhekheni yengilazi ecacile. Imvubelo iwela obishini oluthambile, uhlamvu ngalunye lubamba ukukhanya okufudumele njengoba lukhukhuleka lushona phansi, luqale ukucwila oketshezini olungaphakathi kubhekha. Le ngxubevange yakha indawo okugxilwe kuyo yesehlakalo, igcizelela kokubili ubuthakathaka nokubaluleka kwalesi senzo—umphisi webhiya wengeza ukuphila ngokoqobo ku-wort, obeka inkundla yokuvubela nokuguquka.

Ibhika ngokwalo, elithweswe iziqu ngemigqa yokulinganisa emhlophe, lihlezi liqinile etafuleni lezinkuni. Iqukethe uketshezi olusagolide oluphaphathekile, olucacile kodwa olunokuncane nje kokujula, okubonisa ukukhanya okufudumele okungena ngefasitela eliseduze. Amanye ama-granules asevele efinyelele phansi ku-beaker, enza ungqimba olunesihlabathi oluthambile, kuyilapho amanye enyakaza phakathi nothela ekumisweni, eqandiswe ngesikhathi. Uketshezi luyabenyezela kancane, okuphakamisa amandla kanye nokulindela umsebenzi webhayoloji osezoqala.

Kuzungezwe ubhakha kukhona amathuluzi okuhweba ophisi, into ngayinye enomthelela emuzweni wokunakekela nokunemba okukhona enqubweni yokuphisa. Kwesokunxele kukhona i-hydrometer, ingilazi yayo ezacile ihlezi ngokudayayo endaweni yokhuni, isiphetho sayo se-bulb sibheke kancane kusibukeli. I-hydrometer, ithuluzi lokulinganisa amandla adonsela phansi athile, ifanekisela uhlangothi lokuhlaziya lokuphisa: isidingo sokunemba kanye nedatha yokuqondisa ubuciko. Ngemuva kwe-hydrometer, iflaski le-Erlenmeyer eligcwele uketshezi olumnyama olunsundu lime lide, izimpawu zalo zokulinganisa zibonakala ngokumhlophe engilazini. Elinye iflaski elincane, elibekwe ngokuqhubekayo ngemuva kwesokudla, liqukethe uketshezi olunethoni efudumele efanayo, olunikeza ukujula kokubunjwa. Womabili amaflask anenela umuzwa waselabhorethri wokwenza isiphuzo, kukhumbuza isibukeli ukuthi le nto yokuzilibazisa—nomsebenzi—iwubuchwepheshe besayensi njengoba iwubuciko.

Kwesokudla, okuphumule kuvuliwe phezu kwetafula, kunencwajana yokubhalela. Amakhasi ayo anemigqa engenalutho abamba ukukhanya, anikeze umbono wokwenza amanothi, ukulungiswa kweresiphi, noma izingodo zokuvutshelwa. Incwadi yokubhalela yengeza isici somuntu ku-tableau—yilapho okubonwayo kuqoshwa khona, kuthathwe izifundo, futhi ukuhlakanipha kotshwala kugcinelwe amaqoqo azayo. Ukuba khona kwawo kugcizelela umuzwa wokugxila okucatshangelwayo endaweni yesehlakalo, okuphakamisa ukuthi umdidiyeli wotshwala akasebenzi ngokunganaki kodwa ngenhloso nokugcina amarekhodi ngokucophelela.

Ukukhanya esithombeni kuyisici esichazayo somoya waso. Imisebe ethambile, esagolide ingena ngefasitela emaphethelweni angakwesokunxele ohlaka, ikhanyisa isandla, imvubelo ewayo, kanye nezitsha zengilazi ezinokukhanya okungokwemvelo okufudumele. Izinhlamvu zokhuni zetafula zigqanyiswe ngombala onsundu ocebile, ukuthungwa kwawo kugqame ngokugqamile, kugxilisa ukwakheka endaweni esemaphandleni, yokuphisa ekhaya. Iwindi ngokwalo libonakala ngokwengxenye, uhlaka lwalo lulula futhi alupholishiwe, lwengeza ubuqiniso besilungiselelo. Ukuhlangana kokukhanya nesithunzi kunikeza isithombe sonke ukujula nokufudumala, okudala ithoni ethokomele, ecishe ibe nenhlonipho—njengokungathi isenzo sokuphonsa imvubelo akuwona nje ubuchwepheshe, kodwa umkhuba.

Isandla somthengisi singenye indawo okugxilwe kuyo, evezwa ngokucacile nangokucophelela. Ithoni yesikhumba ingokwemvelo ngaphansi kokukhanya okufudumele, ngemininingwane ecashile yemithambo nemisipha ebonakalayo, ephakamisa ukulawula nokuzinza. Isandla sibamba isaka le-foil ngobunono kodwa siqinile, siqinisekisa ukuthi imvubelo ithululelwa emfudlaneni olinganisiwe esikhundleni sokulahla ngokunganaki. Lesi senzo sidlulisela inhloso, ukugxila, kanye nomkhuba owenziwe umuntu ojwayelene nezigaba ezithambile zokuvutshelwa.

Sekukonke, lesi sithombe singaphezu kokuvezwa kwamathuluzi nezenzo—sidlulisela ifilosofi yokuzenzela. Ilinganisa isayensi nobuciko, ukunemba nothando. Ukuthelwa ngokucophelela kweyeast ebhikeni kuhlanganisa inqubo ecatshangelwayo yokuguqula izithako ezingavuthiwe zibe okuthile okukhulu: isiphuzo esiphilayo, esibilayo. Imvelo ye-rustic, netafula lakhona lokhuni nokukhanya kwemvelo, igcizelela izimpande zalo msebenzi kusiko nesineke, kuyilapho ukuba khona kwamathuluzi esayensi namanothi kugqamisa indlela eqondile yomenzi wotshwala. Isithombe siveza ukuthi lesi sikhathi, nakuba sincane, sibucayi futhi sigcwele incazelo: siyisiqalo esithulile senguquko ezogcina ifinyelele ekwabelaneni ngesiphuzo, ingqikithi yesiko lokuphuza utshwala.
