Isithombe: I-Stainless Steel Fermentation Tank ene-NEIPA esebenzayo

Isithombe sithwebula ukubuka okuseduze kwethangi lokubilisa lensimbi engenasici, elitholakala ngaphakathi kwendawo yokuphisa utshwala yesimanje. Ingaphezulu lethangi liyabenyezela ngaphansi kokukhanya okuzungezile kwesikhungo, libonisa ingaphandle layo elipholishiwe, eline-dimple elingagcini nje ngokubonisa ukukhanya okubenyezelayo okucashile kodwa futhi ligcizelela ukuqina okumangelengele kwemishini yokuphisa utshwala ezimbonini. Umumo wayo oyisilinda ulawula uhlaka, ngokushesha udonsela iso efasiteleni lengilazi eliyindilinga elishumekwe ngaphambili komkhumbi.

Ngaleli windi lesitayela se-porthole, okuqukethwe ethangini kuyembulwa: uketshezi olunamagwebu, olusagolide-owolintshi olubilayo. Lena i-New England IPA, noma i-NEIPA, isitayela sikabhiya esidume ngokubonakala kwayo okukhanyayo, okunejusi kanye nenkungu, okubangelwa amaprotheni amisiwe, ama-hop particulate, ne-yeast esasebenza. Uketshezi olungaphakathi lubonakala luguqubele kodwa lugqamile, okubonisa amandla okubila. Ungqimba oluncane kodwa olusebenzayo lwegwebu lunamathela phezulu, lubonisa umsebenzi wemvubelo oqhubekayo kanye nokukhululwa kwe-carbon dioxide njengoba ushukela ugaywa. Isithombe esibukwayo sidlulisa kokubili ubusha namandla, isifinyezo sikabhiya ongakaqedwa kodwa ophilayo ekuguqulweni kwawo.

Okunamathiselwe ngaphandle kwethangi, ngakwesokudla nje kwengilazi, ithermometer ecwebile yedijithali enesibonisi esiluhlaza esikhanyayo, esikhanyiselwe ngemuva. Amadijithi ayo acwebile futhi acacile, afunda u-22.0°C (72°F), izinga lokushisa elinembile eligcinelwe ukuvutshelwa. Leli zinga lokushisa lingaphakathi kwebanga elifanele lezinhlobo zeyeast ezivame ukusetshenziswa ekwenzeni ama-IPA, ikakhulukazi lawo aklanyelwe ukugqamisa ama-ester anezithelo nezinhlanganisela ze-hop enamakha. Isibonisi se-thermometer asihlinzeki ngemininingwane esebenzayo kuphela kodwa sengeza isici sesikhathi esizayo, sobuchwepheshe endaweni okungeyona yendabuko yezinto zokusebenza zokuphisa.

Ngaphansi kwefasitela, ithangi linevalvu enomzimba wensimbi nesibambo esimbozwe ngepulasitiki eluhlaza okwesibhakabhaka. Lokhu cishe kuyisampula yembobo noma i-valve yokukhipha amanzi, ithuluzi elisebenzayo elisetshenziswa abaphisi botshwala ukuhlola ubhiya phakathi nokuqhubeka kwawo noma ukuthulula umkhumbi. Umbala ohlukile wesibambo unikeza ikhefu elibonakalayo ngokumelene namathoni ayisiliva womzimba wensimbi. Amabhawodi nokufakwa okuzungeze iwindi nevalvu kugcizelela ukunemba kwemishini kanye nedizayini yenhlanzeko ebalulekile ezindaweni zokuphisa utshwala.

Ingemuva elilufifi libonisa isilungiselelo esibanzi: amathangi engeziwe nezakhiwo zensimbi engagqwali ekugxilweni okuthambile, okuqinisa umbono wendawo ephithizelayo, ehlelekile yophisa utshwala. Izindonga ezinamathayela ampunga kanye nephansi lemboni kubeka imvelo njengento ewusizo kodwa enenjongo. Le ndawo ayinamafuhlufuhlu, okugcizelela ubungcweti nenhlanzeko—isici esibalulekile sokwenza utshwala.

Sekukonke, isithombe sidlulisa ukulandisa okunamandla kobuciko nesayensi ngokuvumelana. Ithangi lensimbi engagqwali limelela isiko nokuqina kwezimboni; iwindi lengilazi kanye ne-NEIPA ebhayizayo ngaphakathi kufanekisela ubuciko nezinzwa zokuphisa; ithemometha yedijithali igqamisa ukunemba nokulawula abaphisi botshwala besimanje kule nqubo. Isithombe asithwebuli nje isikhashana sokuvutshelwa kodwa ukuhlangana kobuchwepheshe bomuntu, uguquko lwemvelo, nokwengamela kwezobuchwepheshe okuchaza ukukhiqizwa kukabhiya wezikebhe wesimanje.
