Amasu Okulungisa, Ukufaka I-Lagering, kanye Nokucacisa

Qala ukulungisa ngokuphumula kwe-diacetyl okulawulwayo lapho ukubilisa okuyinhloko sekucishe kuqedwe. Khulisa izinga lokushisa liye kuma-50s kuya kuma-60s°F aphezulu amahora angama-24-48. Lokhu kuvumela imvubelo ukuthi imunce i-diacetyl kabusha, ivimbele ukunambitheka kwebhotela futhi iqinisekise ukuphela okuhlanzekile.

Uma ukuphumula kwe-diacetyl sekuphelile, yehlisa kancane kancane izinga lokushisa ukuze upholise. Yehlisa ngamadigri ambalwa nsuku zonke uze ufinyelele amazinga okushisa acishe abe yiqhwa. Amasu okugcina ubhiya ngokuvamile ahilela ukubamba ubhiya ku-32–38°F isikhathi eside. Lokhu kusiza ukuthuthukisa ukucaca nokunambitheka okuthambile.

Isikhathi sokupholisa sincike esitayeleni sikabhiya kanye namandla adonsela phansi. Ama-lager alula angahlanza futhi avuthwe emavikini ama-2-4. Nokho, ama-Munich-style nama-doppelbocks avame ukudinga amasonto ayi-6-12 noma ngaphezulu. Izikhathi ezinde emazingeni okushisa aphansi zinciphisa ama-compounds esibabule kanye ne-ester, okwenza iphrofayili kabhiya ibe ngcono.

Amasu okucacisa angasheshisa ukucaca kokubona kanye nokuzinza kuma-lager. Ukuqhekeka okubandayo, ukugoba okunwetshiwe, kanye nama-fining afana ne-Irish moss ekugcineni kokubilisa noma i-gelatin kwesibili kuyasebenza. Ezinye izinhlobo zemvubelo ziyagoba kakhulu futhi ziyashesha ukucaca, kanti ezinye zidinga lokhu kungenelela ukuze zibukeke zikhanya.

Uma ubeka i-lager, landela izinyathelo eziyisisekelo zokuphatha: gcina i-fermenter ivaliwe ukuze unciphise ukuqoqwa komoya-mpilo, ubeke kahle uma upakisha kusenesikhathi, bese uqapha amandla adonsela phansi ukuqinisekisa ukuqina. Ukuhlanzeka okufanele kanye nokudluliselwa okuthambile kuvikela isimo esiqinile esitholakala ngokupholisa.

Izincomo Zokupakisha Nokukhabhoni Kwama-Lagers

Nquma indlela yokufaka ehambisana nesikhathi sakho kanye nezintandokazi zakho. Ukufaka i-carbonation enamandla kuqinisekisa amazinga ahambisanayo e-lager carbonation kanye nokuqedwa okuqinile. Abapheki bebhiya basekhaya abasebenzisa ama-Cornelius kegs bangalawula ngokunembile amazinga e-CO2 futhi babandise ubhiya ukuze bathuthukise ukumuncwa kwe-CO2.

I-lager yokulungisa amabhodlela isalokhu iyisinqumo esithandwayo kulabo abazisa amasiko kanye nokugcina izimpahla endaweni engaphansi komhlaba. Qinisekisa ukuthi imvubelo eyanele esebenzayo ngokugwema ukupholisa amabhodlela kakhulu. Uma ulungisa i-primer, bala ushukela ngokunembile ukuze ufinyelele izinga olifunayo le-carbonation.

• Izinhloso ezijwayelekile: amavolumu angu-2.2–2.8 e-CO2 kuye ngesitayela.
• I-Pilsners kanye ne-Dortmunder lagers ngokuvamile zihlala cishe amavolumu angu-2.4-2.6.
• I-carbonation ephansi ifanele ama-lager aseMunich kanye nama-lager athile e-amber.

Ukuhlanzeka ngaphambi kokupakisha kubalulekile. Hlanza amabhodlela, amakegi, kanye nemigqa yokudlulisa ukuze kuqinisekiswe ukuthi ishelufu lihlala liqinile. Ukugcwalisa okuhlanzekile kanye nokuthatha umoya-mpilo omncane kusiza ukuvimbela ukunambitheka okungekuhle ngesikhathi sokugcina.

Uma ukhetha i-lager yokulungisa amabhodlela, qapha amazinga okushisa ngesikhathi sokufakwa kwe-carbonation. Gcina izinga lokushisa elihambisanayo lomsebenzi we-yeast, bese ushintshela endaweni yokugcina ebanda uma izinga eliqondiwe selifinyelelwe. Gwema ukufaka i-primer eningi kakhulu kanye ne-lager ebandayo ende ukuze uvimbele ukukhiqizwa kwe-carbonation eningi kakhulu noma ubhiya obuthambile.

I-force carbonation inikeza indlela elawulwa kakhudlwana futhi esheshayo. Sebenzisa ishadi le-carbonation ukuze uqhathanise ingcindezi kanye nokushisa kwamazinga e-lager carbonation afunekayo. Le ndlela iqinisekisa imiphumela efanayo kuwo wonke amaqoqo, inciphisa izikhathi zokulinda.

Gcina irekhodi eliningiliziwe lenqubo yakho. Bhala phansi amanani okugcoba, ingcindezi ye-keg, isikhathi sokulungisa, kanye ne-carbonation elinganisiwe. Amarekhodi anjalo asiza ekuphindaphindeni impumelelo kanye nokulungisa imigomo yama-lagers esikhathi esizayo.

Izibonelo Zeresiphi Namanothi Okwenza Ubhiya Ngemvubelo Ye-Wyeast 2042-PC Danish Lager

I-Wyeast 2042 ilungele ukwenziwa kwe-Dortmunder Export, i-Pilsner, kanye nezinye izinhlobo ze-lager ezihlanzekile. Inikeza isiphetho esiqinile, esomile esinophawu lwe-hop olukhanyayo. Sebenzisa i-Pilsner noma i-Pilsner kanye ne-adjunct encane yaseMunich njenge-base malts. Le nhlanganisela yengeza umzimba we-malt omnene ngaphandle kokunqoba ama-hops.

Ngezansi kunencazelo emfushane yebhetshi lama-dortmunder elingama-galoni angu-5. Lungisa amanzi nosawoti ukuze kube lukhuni kancane kancane. Lokhu kuzothuthukisa ukunambitheka kwama-noble hops.

• I-malt ye-Pilsner engamakhilogremu angu-9–10
• 1–1.5 lb Vienna noma iMunich elula
• Hlanza 150–152°F ukuze unciphise umswakama
• I-IBU 18–25 isebenzisa i-Saaz noma i-Hallertau
• Ukuqondisa kwe-OG 1.048–1.056
