Koj puas tau xav tias vim li cas qee cov npias saj tshiab thiab huv si thaum lwm tus muaj zog lossis fruity tsw? Qhov tseem ceeb nyob rau hauv qhov sib txawv ntawm lagering vs fermenting. Fermenting yog cov txheej txheem uas cov poov xab hloov cov suab thaj rau hauv cawv, tsim thawj qhov tsw ntawm npias. Lagering ua raws fermenting, koom nrog lub npias so ntawm qhov txias txias. Nyob ib ncig ntawm 68.5% ntawm cov npias thoob ntiaj teb tau ua lag luam. Cov kauj ruam no softens lub flavors thiab qhia meej rau npias, ua rau ib tug smoother haus raws li cov tshuaj hloov maj mam mus ntxiv rau lub caij txias no.
Fermentation yog thawj kauj ruam. Cov poov xab hloov cov suab thaj rau hauv cawv thiab tsw. Qhov no ua rau lub hauv paus ntawm npias.
Lagering tuaj tom qab fermentation. Nws txhais tau tias cia npias txias rau lub lis piam lossis hli. Qhov no ua rau npias ntshiab, du, thiab nkig.
Ale poov xab ua haujlwm zoo tshaj plaws thaum nws sov. Nws muab fruity thiab ntsim flavors. Lager poov xab ua haujlwm zoo dua thaum nws txias. Nws muab huv si thiab me ntsis saj.
Nws yog ib qho tseem ceeb los tswj qhov kub thiab txias thaum lub sij hawm fermentation thiab lagering. Qhov no pab tsim lub npias tsw. Nws tseem txwv tsis pub cov saj tsis zoo los ntawm kev tsim.
Ib qho diacetyl so thaum lub sij hawm lagering yog pab tau. Nws tshem tawm pliaj buttery tsw. Qhov no ua rau npias zoo dua.
Lub sijhawm ua lag luam ntev dua ua rau npias kom pom tseeb thiab sib npaug. Koj yuav tsum tau ua siab ntev kom tau txais txiaj ntsig zoo tshaj plaws.
Lagering pab npias kav ntev. Nws ua kom flavors ruaj khov thiab npias tshiab.
Homebrewers tuaj yeem lager npias hauv txoj kev yooj yim. Lawv tuaj yeem siv lub tub yees lossis hauv qab daus txias. Lawv yuav tsum ua kom qhov kub thiab txias tsis tu ncua thiab saib cov poov xab kom zoo.
Fermentation yog ib feem tseem ceeb ntawm brewing. Ua npias, koj ua ntej ua kua qab zib hu ua wort. Cov poov xab ntxiv rau wort, thiab tom qab ntawd cov txheej txheem pib. Cov poov xab yog cov khoom me me uas noj cov suab thaj hauv wort. Thaum lawv noj, lawv ua cawv thiab carbon dioxide. Qhov no yog li cas npias tau txais nws cov cawv thiab npuas.
Cov txheej txheem fermentation muaj ob peb kauj ruam tseem ceeb. Nov yog cov npe yooj yim ntawm qhov tshwm sim:
Koj muab cov poov xab zoo rau hauv qhov txias wort.
Cov sib tov nkag mus rau hauv lub nkoj fermentation, thiab cov poov xab pib ua haujlwm ntawm cov suab thaj.
Koj ua kom qhov kub thiab txias kom cov poov xab ua nws txoj haujlwm zoo.
Tom qab lub ntsiab fermentation, koj tsiv lub npias mus rau ib tug txias tank. Qhov no yuav pab kom cov flavors tau zoo dua thiab npias kom pom tseeb.
Thaum kawg, koj muab cov npias tso rau hauv lub raj mis, cov kaus poom, lossis kegs. Carbonation tuaj yeem tshwm sim los ntawm nws tus kheej lossis ntxiv.
Tswv yim: Nco ntsoov xyuas koj npias lub ntiajteb txawj nqus ua ntej thiab tom qab fermentation. Qhov no qhia koj thaum nws ua tiav thiab muaj cawv ntau npaum li cas hauv koj lub npias.
Poov xab muaj ib txoj hauj lwm tshwj xeeb hauv brewing. Thaum koj ntxiv cov poov xab rau wort, tshuaj tiv thaiv pib. Cov poov xab zom zom cov suab thaj xws li qabzib thiab fructose. Ua ntej, cov suab thaj no hloov mus ua ib yam dab tsi hu ua pyruvate. Ces, pyruvate hloov mus rau hauv acetaldehyde thiab tom qab ntawd mus rau hauv ethanol , uas yog cawv hauv npias. Cov pa roj carbon dioxide yog tsim nyob rau tib lub sijhawm, yog li npias tau fizzy.
Cov kws tshawb fawb tau kawm txog qhov no tau ntev. Lawv kawm tau li ntawd poov xab yog cov muaj sia nyob uas loj hlob thiab pab nrog fermentation. Cov txheej txheem ua haujlwm zoo tshaj plaws thaum tsis muaj oxygen ntau. Poov xab nyiam ua cawv thaum muaj suab thaj ntau. Qhov no hu ua Crabtree effect. Nws pab cov poov xab kov lwm cov microbes los ntawm kev haus cawv, uas txwv tsis pub lwm yam los ntawm kev loj hlob.
Qhov kub siv rau fermentation hloov li cas npias saj. Txhua tus npias style siv cov txheej txheem fermentation thiab kub. Piv txwv li, ales feem ntau ferment ntawm 62 ° F thiab 75 ° F (17 ° C txog 24 ° C). Lagers xav tau txias txias, txog 46 ° F txog 58 ° F (8 ° C txog 14 ° C). Qee cov Belgian beers, zoo li saisons, tuaj yeem ferment ntawm qhov kub thiab txias, txawm tias mus txog 85 ° F (29 ° C).
Ntawm no yog ib lub rooj los qhia qhov ntsuas kub li ib txwm rau ntau hom npias:

Thaum koj tswj qhov kub thiab txias thaum lub sij hawm fermentation, koj pab cov poov xab ua kom zoo flavors. Qhov sov sov tuaj yeem muab cov txiv hmab txiv ntoo los yog ntsim tsw. Cov txias txias ua rau npias saj huv si thiab nkig. Xaiv cov txheej txheem fermentation thiab kub yog qhov tseem ceeb rau kev ua npias zoo.
Qee cov beers saj huv heev thiab nkig. Qhov no yog vim kev lag luam. Lagering txhais tau hais tias ua kom npias txias rau lub sijhawm ntev tom qab fermentation. Lo lus los ntawm German thiab txhais tau tias 'kho.' Brewers nyob rau sab qaum teb Bavaria pib lagering nyob rau hauv 1300s. Lawv muab npias tso rau hauv lub cellars uas khawb rau hauv toj. Cov cellars ua haujlwm zoo li lub fridges ntuj thiab khaws npias tshiab. Nyob rau tib lub sijhawm, brewers pom tias qhov no ua rau npias saj zoo dua thiab kav ntev dua. Qhov no yog li cas lub lager style pib.
Ib qho poov xab tshwj xeeb hu ua Saccharomyces pastorianus ua lagering tau. Cov poov xab no ua haujlwm ntawm qhov txias dua li cov poov xab. Nyob rau xyoo 1500, ib txoj cai Bavarian tau hais tias npias tuaj yeem ua rau lub hlis txias xwb. Txoj cai no tau pab txwv tsis pub npias los ntawm kev lwj thiab ua rau cov brewers siv txias cia. Tom qab ntawd, fridges tau tsim nyob rau hauv 1800s. Qhov no cia tib neeg lager npias txhua xyoo. Niaj hnub no, lager yog ib qho ntawm cov neeg nyiam tshaj plaws hauv ntiaj teb.
Lagering tsis yog tso npias hauv lub tub yees xwb. Koj yuav tsum ua raws cov kauj ruam kom tau npias zoo. Nov yog cov kauj ruam tseem ceeb:
Ua ntej, cia npias ferment ntawm qhov kub thiab txias. Cov poov xab maj mam hloov cov suab thaj rau hauv cawv thiab carbon dioxide.
Tom ntej no, tsa qhov kub thiab txias rau lub sijhawm luv luv. Qhov no hu ua diacetyl so. Nws pab cov poov xab tshem tawm cov tsw phem, zoo li buttery saj.
Tom qab ntawd, txo qhov kub thiab txias dua. Khaws lub npias cia li saum toj no khov rau lub lis piam lossis hli. Cov poov xab ua hauj lwm maj mam. Nws tshem tawm cov suab thaj ntxiv thiab tshem tawm, ua rau lub npias ntshiab.
Khaws qhov kub thiab txias. Yog tias nws hloov pauv, cov poov xab tuaj yeem ntxhov siab thiab ua rau cov tsw tsw phem.
Cov kauj ruam cia txias yog ib qho tseem ceeb rau lub lag luam huv si, nkig. Lub npias tau smoother thiab cov flavors ua softer.
Tswv yim: Ua siab ntev. Qhov ntev koj lager koj npias, qhov tseeb thiab sib npaug nws yuav yog.
Nws yog ib qho tseem ceeb los tswj qhov kub thiab txias thaum lagering npias. Koj feem ntau khaws cov npias ntawm 33 ° F thiab 50 ° F. Ntau tus brewers siv 34 ° F txog 40 ° F rau npias huv. Qee cov lagers, zoo li German Pilsner, xav tau txias dua. Lwm tus, zoo li Vienna Lager, ua tau zoo ntawm qhov sov sov.

Khaws qhov kub kom ruaj khov pab cov poov xab ua tiav nws txoj haujlwm. Nws tseem txwv tsis pub cov tsw phem los ntawm kev tsim. Txias ua rau cov tshuaj hloov pauv, yog li koj yuav tsum tau tos tsawg kawg ib hlis. Qhov no qeeb, txias txheej txheem muab lager nws pom tseeb thiab du saj.
Fermentation yeej ib txwm yog thawj kauj ruam hauv brewing. Koj ntxiv cov poov xab rau wort, thiab cov poov xab noj cov suab thaj. Qhov no ua rau cawv, npuas, thiab thawj qhov tsw. Lagers ferment ntawm txias txias, txog 50 ° F (10-12 ° C). Qhov no pab cov poov xab noj qab nyob zoo thiab ua haujlwm zoo.
Lagering pib tom qab fermentation tiav. Koj ua kom npias txias dua, nyob ib ncig ntawm 30 ° F (-1 ° C). Npias nyob txias mus ntev. Qhov no hu ua lub sijhawm lagering. Lub npias tau pom meej dua thiab cov flavors ua smoother.
Kev hloov ntawm fermenting mus rau lagering yog qhov tseem ceeb. Nov yog qhov feem ntau tshwm sim: 1. Cia npias ferment ntawm qhov kub thiab txias. 2. Tsa qhov kub kom txog li 57 ° F (14 ° C) rau lub sijhawm luv luv. Qhov no hu ua diacetyl so. Nws pab tshem tawm cov tsw phem. 3. Txias lub npias mus rau ze rau lub freezing rau lagering. 4. Cia npias txias li 35 hnub. Qhov no ua rau npias huv si, nkig, thiab meej.
Lus Cim: Tom qab lagering, pom yuav siv cov poov xab thiab me me. Qhov no ua rau koj lub lager ci ntsa iab thiab du.
Ntev npaum li cas thiab sov npaum li cas koj ferment hloov lub saj. Lagers ferment ntawm 50-55 ° F (10-13 ° C) kom txog thaum cov suab thaj feem ntau ploj mus. Ib qho diacetyl so ntawm 60-65 ° F (15-18 ° C) kav ob peb hnub.

Lager poov xab muab rau koj nkig, huv npias tom qab lub sij hawm ntev, txias lagering.
Fermentation yog thaum feem ntau npias flavors tau ua. Cov poov xab noj cov suab thaj hauv wort thiab ua rau cawv, npuas, thiab cov tshuaj tsw qab. Cov tebchaw no muab txhua lub npias nws tus kheej saj thiab tsw. Qee cov ntsiab lus tseem ceeb ntawm fermentation yog:
Esters: Cov no ua rau npias tsw qab los yog paj, zoo li txiv tsawb lossis txiv apple. Cov poov xab ua esters los ntawm kev sib xyaw cawv thiab acids.
Cov cawv ntau dua: Cov no ua rau muaj zog, qee zaum ntsim los yog fruity flavors. Ntau dhau tuaj yeem saj zoo li tshuaj.
Sulfur compounds: Cov no tuaj yeem hnov zoo li cov qe lwj lossis cov zaub mov siav. Txawm tias me ntsis tuaj yeem hloov pauv npias tsw.
Aldehydes: Cov no tuaj yeem ua npias saj 'ntsuab' lossis tsis tiav. Acetaldehyde yog ntau thiab saj zoo li cov kua ntsuab.
Organic acids: Cov no ntxiv me ntsis qaub thiab pab sib npaug ntawm npias.
Cov poov xab, qhov kub thiab txias li cas koj ferment hloov cov flavors. Qhov kub thiab txias ua rau esters ntau dua thiab muaj cawv ntau dua. Cov cua txias txias ua kom tsw qab thiab huv.
Lagering yog thaum npias so txias tom qab fermentation. Cov kauj ruam no yuav pab kom du thiab ntxuav cov tsw. Thaum lub sij hawm lagering, cov poov xab ua haujlwm maj mam los kho cov khoom seem. Nov yog qhov tshwm sim thaum lagering:
Cov poov xab ua rau cov suab thaj ntxiv thiab cov tsw qab xws li diacetyl (buttery) thiab acetaldehyde (txiv apples).
Flavors mix thiab mellow, yog li npias saj smoother thiab sib npaug.
Txias pab cov poov xab thiab cov khoom me me nyob, ua kom npias ntshiab.
Hop bitterness tau softer, thiab tag nrho cov flavors muab rau ib tug crisp tiav.
Koj tau npias uas huv si, du, thiab yooj yim haus. Qhov ntev koj lager, qhov zoo dua koj npias saj.
Lagering thiab fermenting ob leeg hloov li cas npias saj. Fermentation ua rau lub ntsiab tsw. Koj tuaj yeem tau txais cov txiv hmab txiv ntoo, ntsim, lossis cov ntawv muaj zog, nyob ntawm cov poov xab thiab kub. Lagering ces smooths tawm cov flavors. Nws tshem tawm hnyav saj thiab muab txhua yam ua ke.

Koj tuaj yeem qhia ales thiab lagers sib nrug los ntawm cov poov xab lawv siv. Nov yog yam tseem ceeb uas yuav tsum paub:
Ale poov xab hu ua Saccharomyces cerevisiae . Nws ua haujlwm ntawm qhov kub thiab txias, ntawm 60-78 ° F (16-26 ° C). Cov poov xab no ntab mus rau saum thaum nws ferments.
Lager poov xab hu ua Saccharomyces pastorianus . Nws nyiam qhov txias dua, nyob ib puag ncig 42-58 ° F (9-14 ° C). Cov poov xab no nkag mus rau hauv qab thaum fermentation.
Ale poov xab ua rau ntau esters thiab phenols. Cov no muab ales fruity thiab ntsim saj.
Lager poov xab ua haujlwm qeeb thiab ua kom tsawg esters. Qhov no muab cov lagers huv si thiab nkig tsw.
Lager poov xab yog ib qho sib xyaw ntawm ale poov xab thiab cov poov xab txias-hlub.
Poov hloov li cas npias saj. Ale poov xab ua rau ntau esters thiab phenols. Cov no muab ales tsw zoo li txiv tsawb lossis clove. Lager poov xab ua hauj lwm nyob rau hauv qis kub thiab ua kom tsawg ntawm cov flavors. Lagers saj huv si, nkig, thiab du. Ales muaj bold thiab complex flavors. Lagers cia lub malt thiab hops sawv nrog ib tug sib zog saj.
Ob leeg ales thiab lagers pib nrog fermentation, tab sis lawv ua nws txawv. Ales ferment nyob rau hauv chav tsev kub. Cov poov xab ua haujlwm nrawm thiab ua kom muaj zog, fruity, los yog ntsim tsw. Lagers ferment ntawm txias txias. Cov poov xab ua hauj lwm maj mam thiab ua kom tsawg dua flavors. Tom qab fermentation, lagers mus los ntawm lagering. Qhov no yog kauj ruam cia txias uas kav ntev li ob lub lis piam lossis hli. Lub npias tau clearer thiab cov flavors ua softer.
Lagering yog dab tsi ua lagers txawv ntawm ales. Thaum koj lager npias, koj cia nws txias kom ntev. Qhov no yuav pab kom cov khib nyiab kho thiab ua kom cov tshuaj hloov pauv sai. Lub npias zoo nkaus li ntshiab thiab saj huv. Lagering kuj tshem tawm cov txiv hmab txiv ntoo esters thiab lwm yam ntxiv, yog li lub npias zoo nkaus li du. Lagers feem ntau muaj qhov sib dua thiab ua kom zoo dua qub dua li ales. Koj tau txais ib qho nkig tiav thiab haus dej qab zib.
Tswv yim: Yog tias koj xav tau npias du thiab yooj yim, sim ua lag luam. Yog hais tias koj nyiam bold thiab fruity saj, ales yog ib tug zoo xaiv.
Nov yog ib lub rooj los qhia tias ales thiab lagers txawv li cas:

Kub thiab lub sij hawm hloov li cas koj npias puv. Ales ferment ceev ceev ntawm qhov kub thiab txias. Qhov no ua rau ntau esters thiab complex flavors. Lagers ferment qeeb ntawm qhov txias txias. Qhov ntev, txias lagering kauj ruam ua rau npias smooth, meej, thiab nkig. Yog tias koj tswj qhov kub thiab txias, koj tau txais ib qho lag luam zoo uas tsis muaj qhov tsis zoo. Cov kauj ruam ua rau ales bold thiab pos huab. Lagers yog huv si, ntshiab, thiab refreshing.
Lus Cim: Qhov txawv ntawm ale thiab lager tsis yog cov poov xab xwb. Nws kuj yog hais txog yuav ua li cas koj ferment thiab hnub nyoog lub npias. Lub sij hawm thiab kub ob qho tib si tseem ceeb rau qhov kawg saj.
Ob qho fermenting thiab lagering hloov pauv li cas npias saj thiab tsw. Thaum lub sij hawm fermentation, poov xab ua ntau yam uas muab npias nws tshwj xeeb tsw. Qee qhov no yog diacetyl, uas saj zoo li butter, thiab acetaldehyde, uas saj zoo li txiv apples ntsuab. Sulfur compounds kuj tuaj yeem tshwm sim thiab hnov tsw zoo li cov qe lwj lossis cov zaub mov siav. Yog tias koj siv cov poov xab noj qab haus huv thiab khaws cov npias ntawm qhov kub thiab txias, cov tsw phem no ploj mus. Qhov no hu ua diacetyl so.
Lagering pab smooth tawm cov flavors ua thaum lub sij hawm fermentation. Thaum koj khaws npias txias rau lub lis piam los yog hli, cov flavors sib tov thiab tau softer. Hop bitterness tau tsawg zog, thiab npias saj ntau sib npaug. Cov poov xab ua haujlwm maj mam hauv qhov txias thiab pab ntxuav cov khoom seem. Cov poov xab, malt, thiab hops koj xaiv kuj hloov qhov kawg saj thiab tsw. Piv txwv li, cov hops zoo li Saaz los yog Hallertau muab qhov muag muag, ntsim tsw. American hops zoo li Cascade ntxiv cov tsw qab citrus. Cov dej uas koj siv thiab nws cov zaub mov kuj hloov li cas npias xav thiab saj. Los ntawm kev hloov lub sijhawm, qhov kub thiab txias, thiab qhov koj muab tso rau hauv, koj ua npias saj thiab tsw koj xav li cas.
Muaj qhov sib txawv loj npaum li cas npias ntshiab thiab du yog tias koj tsuas yog ferment nws lossis yog tias koj tseem lager nws. Txias fermentation slows poov xab, yog li koj tau txais ib tug huv si saj thiab fuller lub cev. Thaum koj lager npias, poov xab thiab me me nyob rau hauv qab. Qhov no ua rau npias zoo li ci ntsa iab.
Lagering ua rau npias xav tias nkig thiab refreshing.
Txias crashing txhais tau hais tias chilling npias sai ua ntej bottling. Qhov no pab cov proteins thiab poov xab lo ua ke thiab poob tawm. Nws nres haze thiab muab rau koj npias npias.
Cov fermentation sov tuaj yeem ua rau npias huab thiab ntxhib. Cov poov xab ua haujlwm nrawm heev thiab tawm ntau yam khoom qab.
Khaws qhov kub kom zoo thaum ob kauj ruam yog qhov tseem ceeb. Yog tias koj ua, koj nres qhov tsw phem thiab tau txais cov npias ntshiab, uas muaj ntau tus neeg nyiam.
Koj tuaj yeem ua npias ntev dua los ntawm fermenting thiab lagering nws txoj kev yog. Lagering ua rau npias clearer thiab ruaj khov. Qhov no ua rau npias tshiab thiab saj zoo rau lub sijhawm ntev. Thaum ua lag luam, cov poov xab ua haujlwm qeeb. Nws tshem tawm tej yam uas koj tsis xav tau thiab pab npias tau zoo dua. Cov pH poob me ntsis, uas pab kom npias muaj kev nyab xeeb thiab tsis tshua muaj kev lwj.
Cov kws tshawb fawb pom tias yuav ua li cas koj khaws npias tom qab cov kauj ruam no tseem ceeb. Yog koj khaws npias txias thiab deb ntawm huab cua, nws muaj hnub nyoog qeeb thiab ua kom nws tsw. Cov iab hauv npias tawg sai dua yog tias npias sov. Yog tias koj khaws npias txias, koj tiv thaiv cov no thiab ua kom npias tasting tshiab. Txoj cai pH, nyob nruab nrab ntawm 4.2 thiab 4.6 , kuj tseem txwv tsis pub huab cua thiab ua kom npias tsis muaj kab mob.
Tswv yim: Nco ntsoov khaws koj cov npias hauv qhov chaw txias, tsaus. Qhov no pab nws saj zoo rau lub sijhawm ntev.
Brewing tsis yog tshiab. Tib neeg tau ua dej fermented rau ntau txhiab xyoo. Ntawm Jiahu hauv Suav teb, archaeologists pom cov tais diav qub. Cov khoom no muaj txog 9,000 xyoo. Lawv muaj cov cim qhia ntawm zib mu, mov, txiv hmab txiv ntoo hawthorn, thiab txiv hmab txiv ntoo qus. Cov kws tshawb fawb tau siv cov tshuab tshwj xeeb los kuaj xyuas cov dej qab zib no. Cov cuab yeej yog chromatography thiab loj spectrometry. Lawv tau ua pov thawj tias cov no yog qee yam ntawm thawj fermented dej qab zib. Thaum cov kws tshaj lij ua cov dej haus qub no dua, lawv pom txog 9% cawv. Qhov saj zoo li qhov koj xav tau los ntawm daim ntawv qhia qub heev.
Lwm qhov chaw kuj ua npias ntev dhau los. Hauv Ixayees lub qhov tsua Raqefet, npias tseem muaj hnub nyoog 13,000 xyoo. Cov npias thaum ntxov no yog tuab thiab mushy.
