Isithombe: I-Brewer Ehlola Ukuvutshelwa kwe-Kölsch Ethangini Lensimbi Engenasici

Lesi sithombe sibonisa isikhashana sokugxilisa ingqondo nokunemba kobuchwepheshe ngaphakathi kwendawo yokuphisa utshwala ekhanyiswe kalufifi. Maphakathi nendawo kume umdidiyeli wotshwala oseminyakeni yawo-30, ukukhuluma kwakhe kuphawulwa ukukhathazeka nokugxila njengoba ehlolisisa ithangi lokubilisa lensimbi engenasici eliqukethe ubhiya wesitayela se-Kölsch. Ukukhanya okuthambile, oku-amber koketshezi olubilayo kukhanyisa iwindi lembobo yomkhumbi, kukhipha ukukhanya okufudumele ebusweni bomshini wokuphisa utshwala nejazi lelebhu. Ukukhanya nomkhathi kuhlangana ukuze kuvuse umuzwa wakho kokubili ubuciko nesayensi - umzuzwana umisiwe phakathi kokuzwisisa nokulinganisa.

Isambatho somshini wokuphisa utshwala sibonisa ubungcweti nokunemba: ilebhu elimhlophe qhwa phezu kwehembe elimnyama, ikhola evuleke kancane, imikhono edake ngobuqili ngenxa yamahora omsebenzi. Kwesinye isandla, uphethe ibhodi lokunamathisela elinepeni limile, lilungele ukurekhoda lokho akubonayo. Isiphongo sakhe esinwetshiwe kanye namehlo anciphile adlulisa ingxube yokucabangisisa nokuhlala eqaphile - mhlawumbe ubona iphethini yokuvubela engavamile, noma uqhathanisa izinga lokushisa elilinganiselwe nebanga lakhe elilindelekile. Ukuma kwakhe kuncika kancane ngasethangini, okusikisela ukuzibandakanya komuntu siqu nenqubo eyembuleka phambi kwakhe.

I-stainless steel fermentation tank ilawula ohlangothini lwesokudla lwesithombe. Indawo yayo eyisilinda ibamba ukukhanya okuzungezile okuthambile, okubonisa ama-gradient afiphele ethusi, ithusi, nesithunzi. Imbobo yokubuka ingilazi eyindilinga yembula umnyombo wesenzo: uketshezi olunambala ophuzi phakathi nokuvutshelwa, olubhayizayo futhi oluzungeza amandla emvubelo ephilayo. Igwebu nezinhlayiya ezimisiwe ngaphakathi kwethangi elibenyezelayo ngaphansi kokukhanya, okugcizelela uguquko olwenzekayo - wort eba ubhiya ngokusebenzisa ibhalansi ethambile yekhemistri nobuciko. Amaconsi amancane okujiya abuthana eduze kwembobo yokubuka, aqinise ngobuqili isimo esipholile, esilawulwayo ngaphakathi.

Ngemuva, isilungiselelo sinwebeka sibe ishabhu yokusebenzela kokubili eyezimboni neyobuciko. Amashalofu enziwe ngokhuni akleliswe odongeni olungemuva, anamathuluzi namathuluzi esayensi - ama-hydrometer, ama-thermometer, amasilinda athweswe iziqu, namabhikha engilazi - konke kukhomba esimweni esiqhutshwa yi-methodical kanye nedatha yomsebenzi womphisi utshwala. Ukukhanya okufiphele, okufudumele okuvela ezimpahleni eziphezulu kuveza izithunzi ezinde, ezicabangelayo egumbini lonke, zimboze isikhala endaweni enokuthula. Lokhu kukhethwa kokukhanyisa kugcwalisa isithombe ngekhwalithi yesinema, ukulinganisa okungokoqobo nokuzwakala kwemizwa.

Ukuhlangana kokukhanya nesithunzi esithombeni kugcizelela ubumbaxambili bokuzenzela: umshado wesiko nokuqamba izinto ezintsha, ubuciko kanye nokunemba. Amathoni afudumele, acishe abe yigolide aphakamisa uhlangothi lwemvelo, oluphilayo lwenqubo - imvubelo, i-malt, ukuvutshelwa - kuyilapho ukukhanya okubandayo kwensimbi engagqwali kanye namanothi elebhu acophelelayo amelela isiyalo sesayensi yesimanje esiqinisekisa ukuvumelana kanye nekhwalithi. Ndawonye, bakha isingathekiso esibukwayo sendima yabaphisi botshwala besimanje: umnakekeli wesiko ohlonyiswe ngamathuluzi esayensi.

Ukwakheka kuholela isibukeli ekubukeni kwesendlalelo sencazelo - kusukela efasiteleni lethangi elikhanyayo kuya ebusweni obucabangayo bomshini wokuphisa utshwala, futhi ekugcineni bufinyelele ekujuleni okufiphele kwendawo yokusebenza ngale. Yonke into inikela ekulandiseni kokuxazulula izinkinga nokuxazulula izinkinga, lapho ukuqaphela nokubekezela kubaluleke njengochwepheshe bezobuchwepheshe. Ukuthula kwalesi sikhathi kucishe kubonakale; umuntu angakubona ngeso lengqondo ukugebha kancane kukabhiya obilayo, umsindo othule wamayunithi esiqandisi, kanye nokuhwashaza kwephepha njengoba kuthathwa futhi kuqhathaniswa namanothi.

Lesi sithombe sithwebula okungaphezu kwenqubo yobuchwepheshe; ihlanganisa ingqondo. Umdidiyeli wotshwala akagcini ngokubuka nje kuphela - uyatolika, azivumelanise nezimo, futhi aqinisekise ukuthi ukuvutshelwa kuhlala kuyiqiniso esikweni lamaKölsch. I-Kölsch, eyaziwa ngokulinganisela kwayo okuntekenteke nokucaca okucacile, idinga ukunakwa ngesikhathi sokuvutshelwa, ngokuvamile okwenziwa emazingeni okushisa apholile ukuze iqede ihlanzekile, icolisisiwe. Ukukhathazeka komphisi webhiya nokunemba kubonisa ubuhle bukabhiya, okubonisa isiyalo sokuthola ubulula.

Ekugcineni, lesi sigcawu sidlulisa isici somuntu ngaphakathi kwenqubo eyenziwe ngomshini - izandla, amehlo, nokuzwa okungekho mshini ongakushintsha. Indawo yokuphisa utshwala ngokwayo izizwa iphila, imfudumalo yayo kokubili engokoqobo nengokomfanekiso, iphuma emkhunjini obilayo kanye nasekunakekelweni okuqinile komphisi. Umphumela uyisithombe esidlula isimo saso sezimboni, esiveza ukuphisa njengokubili kobuciko nesayensi - umsebenzi wezandla ochazwa ngokubuka, ukucabangisisa, kanye nokuphishekela ukuphelela okungapheli.
