Kufanele ngiphathe kanjani amanzi namaminerali kuma-lagers aseMunich ngale mvubelo?

Hlosa iphrofayili ye-chloride-forward ukuze uthuthukise ukuceba kwe-malt—engeza usawoti we-calcium ne-chloride njenge-calcium chloride uma kudingeka. Gwema amazinga aphezulu e-sulfate agcizelela ukoma kwe-hop. I-carbonate ephakathi nendawo iyamukeleka kubantu abamnyama abalala, kodwa gcina ukulungiswa kuhlelekile ukuze kulondolozwe uhlamvu lwangempela lwe-Munich.

Yiziphi izinto okufanele zenziwe kanye nezinto okufanele zenziwe ukuze kufakwe i-oxygenating wort ngaphambi kokufaka i-2487?

YIFAKE i-oxygen eyanele lapho iphonswa—sebenzisa i-oxygen emsulwa noma umoya onamandla—ukusekela ukukhula kwemvubelo kanye nokunciphisa okunempilo. UNGAYIPHINDISI i-oxygen ngemva kokuqala kokubilisa, njengoba i-oxygen ingadala ukunambitheka okungafanele. Ukungenisa i-oxygen ngendlela efanele kunciphisa ingozi yokubilisa okubambekile kanye nokwakheka kokunambitheka okungafanele.

Kufanele ngifake nini izakhamzimba zemvubelo, futhi ngani?

Engeza izakhamzimba ze-wort enamandla adonsela phansi noma uma usebenzisa izinketho ezincane zokungenisa umoya-mpilo. Izakhamzimba zisekela ukubiliswa okunempilo, zivumela ukuncishiswa okugcwele, futhi zinciphise ukwakheka komkhiqizo ophumayo. Ziwusizo ikakhulukazi lapho kuhloswe ukubekezelela okuphezulu kwe-ABV yohlobo noma lapho ukuqina kokuphila kungaqiniseki.

Yiziphi izimpawu ezibonisa ukubila okubambekile noma okuhamba kancane futhi ngixazulula kanjani inkinga?

Izimpawu zifaka phakathi i-krausen ebuthakathaka noma engekho, ushintsho oluncane lwamandla adonsela phansi ngemva kwamahora angu-48-72, kanye nomsebenzi ohamba kancane. Hlola ukuthi imvubelo iyaphila yini (cabanga ngomonakalo wokuhamba okubandayo), qinisekisa izinga lokushisa kanye nokufakwa komoya-mpilo, bese ucabanga ukwakha isiqalo esisha noma ukuphinda upheke ngokucindezela okukhulu kwe-lager. Ngemvubelo engavuthwanga kahle noma engavuthwa kahle, ukwenza isiqalo esikhulu kuvame ukuba yisisombululo.

Ngingabhekana kanjani nokunambitheka okungafanele njenge-sulfury notes, i-phenolics, noma i-acetaldehyde?

I-sulfury/hydrogen sulfide ivame ukusulwa ngokuhamba kwesikhathi endaweni ebandayo—ivumela ukubanda isikhathi eside. I-Diacetyl isabela ekuphumuleni kwe-d (ukuphakamisa izinga lokushisa amahora angu-24-72). I-acetaldehyde ye-apula eluhlaza ivame ukwehla ngokuhamba kwesikhathi. Izinhlamvu ze-phenolic zingase zibonise ukungcola noma ukwehla kwezinga lokushisa; ukulungiswa isikhathi eside, ukuhlolwa kokuhlanzeka, noma ukuphinda kusetshenziswe uhlobo oluhlanzekile kungadingeka.

Kunini lapho kufaneleka khona ukushintsha noma ukwakha isiqalo esisha?

Uma imvubelo ikwazi ukuqina ngemva kokuhamba okufudumele, noma uma ukubilisa kubonisa umsebenzi omncane ngemva kwamahora angu-48-72, yakha isiqalo noma uphinde usebenzise imvubelo enempilo. Amaqoqo aphezulu e-OG kanye nezikhathi zokuthumela ezinde kwandisa isidingo seziqalisi ezinkulu ukuqinisekisa ukubilisa okuphelele.

Yiziphi izinhloso zokupakisha kanye ne-carbonation ezifanele iMunich Helles kanye neBock ezenziwe nge-Wyeast 2487?

Ngemva kokufaka i-lager efanele kanye nokucacisa kahle, ungabeka i-keg noma ubhodle. I-Munich Helles ivame ukufaka i-carbonate cishe ku-2.3–2.6 volumes CO2. Ama-bocks avame ukuhlala afana noma aphansi kancane kuye ngokuthi i-substyle injani. Lawula umoya-mpilo ngesikhathi sokupakisha kanye nokufaka ngemva kokupholisa ukuze uqine eshalofini.

Zibaluleke kangakanani izikhwama ezibandayo kanye nokuhamba okubandayo lapho u-oda i-Wyeast 2487?

Kubaluleke kakhulu. Abathengisi batusa ukwengeza amaphakethe abandayo ngoba ukuphila kwemvubelo ewuketshezi kuyehla lapho kuthuthwa ngokufudumele. Amaphakethe abandayo asiza ekulondolozeni impilo yamaseli, andise inani lamaseli elisebenzayo ngosuku lokuphuza utshwala futhi anciphise ingozi yokubilisa ngaphansi noma ukunamathela.

Ngingayigcina kanjani i-Wyeast 2487 ngaphambi kokusebenzisa futhi kuthiwani ngezinsuku ezingcono kakhulu ngaphambi kokusetshenziswa?

Faka esiqandisini kuze kube yilapho uyisebenzisa, gwema ukubanda noma ukufudumala isikhathi eside, bese uyisebenzisa ngaphakathi kwefasitela lomkhiqizi ngaphambi kwesikhathi. Uma imvubelo ibilokhu ifudumala noma isiseduze nokuphelelwa yisikhathi, hlela isiqalo esikhulu bese uqapha umsebenzi wesiqalo ukuqinisekisa ukuthi iyasebenza.

Ubhiya obuvutshelwe nge-Wyeast 2487 buhlala isikhathi esingakanani buqinile eshalofini?

Ngokugcina ngokucophelela ubanda, ukupholisa kahle, kanye nokuthathwa komoya-mpilo ophansi ngesikhathi sokupakisha, ubhiya obuvutshelwe nge-2487 bungafinyelela ukuzinza okufana nokwezentengiselwano. Ukugoqeka okuphakathi kanye nokugoqeka isikhathi eside kunegalelo ekucaceni nasekuzinzeni kwe-colloidal, okwandisa isikhathi sokuphila uma bugcinwa bubanda.

Yikuphi ukubonwa komphakathi okufanele ngikulindele mayelana nomlingiswa ka-2487?

Iningi labapheki bebhiya lincoma ubuntu bayo obufana ne-malt kanye nomuzwa womlomo. Abanye baphawula ukuthi inganuka yomile kancane noma ibaba kancane ngaphambi kokuphuza isikhathi eside. Ukuba khona kwe-Ester ngokuvamile kuphansi, kodwa i-ester encane ingabonakala kubhiya osemusha kakhulu. Imibono iyahlukahluka nge-diacetyl—abaningi benza i-d-rest ukuze baphephe.

Ungakwazi yini ukufingqa izindlela ezinhle kakhulu zokwenza ubhiya nge-Wyeast 2487-PC?

Faka inani lamaseli aphilile (isiqalo noma amaphakethe amaningi) ekugcineni okupholile (cishe ku-45–48°F), hlala uqinile kuze kube yilapho uqeda, yenza ukuphumula kwe-diacetyl eduze kokuphela (50–56°F amahora angu-24–72), bese ushaya umkhuhlane bese ulala amasonto angu-6–8 ku-~32–38°F. Sebenzisa i-malt-forward grain bill, ukulungiswa kwamanzi e-chloride-forward, ama-noble hops aphansi, i-oxygenation eyanele lapho uphuza, kanye nezakhamzimba zemvubelo ukuze uthole ubhiya obunamandla adonsela phansi.

Yini okufanele ngiyenze uma ngithola ama-ester noma i-acetaldehyde kubhiya osemncane?

Gcina ukubilisa okupholile nokuzinzile futhi uqinisekise ukuthi umoya kanye nezakhamzimba ezanele zifakwa ukuze kuvinjelwe ama-ester amaningi. Uma uthola i-acetaldehyde (i-apula eluhlaza) noma ama-ester kubhiya osemusha, ukubilisa isikhathi eside kanye nesikhathi esibandayo ngokuvamile kuzonciphisa lawa ma-compounds. Uma ukunambitheka okungafanele kuqhubeka, hlola impilo yokubilisa bese ucabanga ngokuyiphinda nge-yeast strain enempilo.
