Ukubekezelela utshwala kucishe kube ngu-9%, ngakho-ke hlela ama-pitch amakhulu kanye ne-oxygenation ukuze uthole ubhiya obuphezulu be-OG.

Ingabe i-2124 ifanelekela ama-lager amnyama nezitayela ze-bock eziqinile?

Yebo. Iphatha iDunkel, iMärzen, iSchwarzbier, kanye nezinhlobo eziningi ze-bock. Ku-Doppelbock noma i-Eisbock, qaphela ukubekezelela utshwala bese usebenzisa iziqalo ezinkulu, i-oxygenation, kanye ne-conditioning ende ukuze ufinyelele ekunciphiseni okuqondiwe ngaphandle kokucindezela imvubelo.

Ngingakwazi yini ukuvundisa izitayela zokuhlola ezifana neCalifornia Common noma iBiere de Garde?

Impela. Abathengisi kanye nokuhlangenwe nakho komphakathi basekela ukubila kokushisa okungu-2124 (phakathi kuya phezulu kwama-60°F) eCalifornia Common naseBiere de Garde. Qinisekisa ukuthi izinga lokushisa liqinile futhi lizinzile ukuze kugcinwe ama-ester nama-fusel elawulwa.

Yiziphi izindlela zokufaka i-carbonation kanye nokuqeda ezinconywayo?

Ukuphoqwa kwe-carbon ema-keg kuyashesha futhi kuyalawuleka. Ukuphoqwa kwe-spunding noma ukulungiswa kwamabhodlela ngokwemvelo kugcina isimo sokubilisa kodwa kudinga ukuqapha ingcindezi. Abapheki abaningi bahlanganisa ukuphoqwa kwe-spunding nokufakwa kwe-carb ekugcineni ukuze kube nokuvumelana.

Kufanele ngibekezelele isikhathi esingakanani futhi ngibe manzi ngemva kokubilisa?

Ngemva kokuphumula kwe-diacetyl, beka umkhuhlane amasonto kuya ezinyangeni kuye ngesitayela kanye nemigomo yokucaca. Ama-lager alula avame ukuzuza amasonto amaningana; ubhiya obunzima kakhulu noma obuqinile buvame ukudinga izinyanga ukuze kuhlanganiswe ukunambitheka okuhle kanye nokukhanya.

Yiziphi izimpawu ezibonisa ukuzulazula kokucindezeleka noma izinkinga ezivela ekuphindeni kwebhola?

Ukuphindaphinda kokunambitheka (ama-ester amaningi, ama-fusel, i-sulfur), ukubila okuhamba kancane noma okungaguquguquki, kanye nokwehluleka ukufinyelela ekunciphiseni okulindelekile kusikisela ukukhukhuleka noma ukucindezeleka. Nciphisa ukuphindaphindwa okulandelanayo, gcina ukuhlanzeka, futhi uvuselele ngamasiko amasha lapho ikhwalithi yehla.

Ngingalungisa kanjani i-sulfur, i-diacetyl, noma ezinye izinto ezinganambitheki kahle?

Isibabule sivame ukuhla ngokuphumula kwe-diacetyl kanye nokulala isikhathi eside. Ku-diacetyl, fudumala kuze kufike ekushiseni kokuphumula lapho amandla adonsela phansi eseseduze nokugcina ukuze uvumele ukumuncwa kabusha. Bhekana nezimbangela eziyinhloko ngokuthuthukisa izinga lokuphuma, i-oxygenation, kanye nezakhamzimba ukuze uvimbele ukuphinda kuvele.

Yini okufanele ngiyenze uma ukubilisa kuhamba kancane noma kubambekile?

Hlola umlando wamandla adonsela phansi kanye nokushisa kuqala. Fudumeza kancane i-fermenter ukuze ivuselele imvubelo, cabanga ngokufaka imvubelo entsha enempilo noma i-starter, bese ufaka izakhamzimba uma kufaneleka. Gwema ukufaka i-oxygen ngemva kokuthi ukubila okusebenzayo sekuqalile; i-oxygen iwukuba i-pitch time kuphela.

Ngingaphinde ngiyishaye kangaki i-Wyeast 2124 ngokuphephile?

Ayikho inombolo eqondile—ukuphepha kuncike ekuphathweni, ekugcinweni, nasezimweni zokubilisa zangaphambilini. Nciphisa ukuphindwaphindwa uma izizukulwane zangaphambilini zibilisiwe zifudumele noma zibonise ukucindezeleka. Shintsha ngezikhathi ezithile ngesiko elisha ukuze unciphise izingozi zokukhukhuleka.

Ingabe umehluko wamakhemikhali phakathi kwama-lager abandayo nafudumele uzohlala usobala?

Akunjalo ngaso sonke isikhathi. Ukuhlolwa kwesitayela se-community xBMT kubonisa ukuthi umehluko wamakhemikhali kanye nezinzwa ungaba ngaphansi kwemingcele yokunambitha uma izinga lokuzwakala, impilo yemvubelo, kanye nokuqina kwezinga lokushisa kulawulwa. Ukulawulwa okuhle kwenqubo kuvame ukufiphaza igebe phakathi kwemiphumela ebandayo nefudumele.

Ingabe kukhona amathiphu asheshayo asebenzayo okuthola imiphumela emihle kakhulu nge-2124?

Beka phambili isiqalo esinempilo esilingana ne-lager, i-oxygenation eyanele lapho iphithizela, kanye namazinga okushisa okubila azinzile. Yenza ukuphumula okufanele kwe-diacetyl, bese ubanda ukuze ulungise isimo. Ukuze uthole izivivinyo ezifudumele, yandisa usayizi wephithi bese uqaphela ukunambitheka okungafanele; vuselela njalo izilimo uma uphinda uphithizela.
