Brewing dej cuam tshuam rau npias nyob rau hauv peb txoj kev: Nws cuam tshuam rau pH ntawm npias, uas cuam tshuam li cas cov npias flavors qhia rau koj palate;nws muab "seasoning" los ntawm sulfate-rau-chloride piv;thiab nws tuaj yeem ua rau muaj ntxhiab tsw los ntawm cov tshuaj chlorine lossis cov khoom paug.
Feem ntau, brewing dej yuav tsum huv si thiab tsis muaj ntxhiab tsw, xws li chlorine los yog pas dej tsw ntxhiab tsw.Feem ntau, cov dej brewing zoo rau kev ua cov mash thiab tsim cov wort yuav tsum nyuaj me ntsis thiab muaj cov alkalinity qis-rau-mob.Tab sis nws nyob ntawm (tsis yog nws ib txwm?) ntawm hom npias koj xav brew thiab cov ntxhia ua cim ntawm koj cov dej.
Feem ntau cov dej los ntawm ob qhov chaw: dej saum npoo av los ntawm pas dej, dej ntws, thiab ntws;thiab dej hauv av, uas yog los ntawm cov dej hauv av.Cov dej saum npoo av zoo li tsis tshua muaj cov ntxhia yaj tab sis siab dua hauv cov organic teeb meem, xws li nplooj thiab algae, uas yuav tsum tau lim thiab tshuaj tua kab mob nrog tshuaj chlorine.Cov dej hauv av feem ntau tsis tshua muaj cov teeb meem organic tab sis siab dua hauv cov ntxhia hauv yaj.
Npias zoo tuaj yeem brewed nrog yuav luag txhua yam dej.Txawm li cas los xij, kev hloov dej tuaj yeem ua rau qhov sib txawv ntawm npias zoo thiab npias zoo yog tias nws ua tiav.Tab sis koj yuav tsum nkag siab tias brewing yog ua noj thiab cov seasoning ib leeg yuav tsis ua rau cov khoom xyaw tsis zoo lossis daim ntawv qhia tsis zoo.
Daim ntawv qhia dej
Koj paub li cas koj cov dej alkalinity thiab hardness?Feem ntau cov ntaub ntawv no muaj nyob rau hauv koj daim ntawv qhia txog dej hauv nroog.Cov ntawv ceeb toom dej feem ntau cuam tshuam nrog kev sim rau cov kab mob, yog li koj feem ntau yuav pom Tag Nrho Alkalinity thiab Tag Nrho Hardness tus lej hauv Cov Qauv Thib Ob lossis Cov Qauv Zoo Nkauj.Raws li ib tug brewer, feem ntau koj xav pom Tag Nrho Alkalinity tsawg dua 100 ppm thiab nyiam dua tsawg dua 50 ppm, tab sis qhov ntawd tsis zoo heev.Feem ntau koj yuav pom Tag Nrho Alkalinity tooj ntawm 50 thiab 150.
Rau Tag Nrho Hardness, feem ntau koj xav pom tus nqi ntawm 150 ppm lossis ntau dua li calcium carbonate.Zoo dua, koj xav pom tus nqi ntau dua 300, tab sis qhov ntawd tsis zoo li.Feem ntau, koj yuav pom tag nrho cov hardness tooj nyob rau hauv thaj tsam ntawm 75 mus rau 150 ppm vim hais tias cov tuam txhab dej tsis xav carbonate scale nyob rau hauv lawv cov kav dej.Qhov tseeb, yuav luag txhua lub nroog cov kais dej, txhua qhov chaw hauv ntiaj teb, feem ntau yuav siab dua hauv alkalinity thiab qis dua hauv qhov tawv dua li peb xav tau rau brewing.
Koj tuaj yeem sim koj cov dej brewing rau tag nrho cov alkalinity thiab tag nrho hardness los ntawm kev siv cov khoom siv kuaj dej, Cov no yog cov khoom siv poob yooj yim zoo ib yam li qhov koj yuav siv rau lub pas dej da dej.
Koj Yuav Ua Li Cas
Thaum koj muaj koj cov ntaub ntawv dej, koj tuaj yeem xam ntau npaum li cas ntxiv.Ib qho kev coj ua yog pib nrog qhov tsis tshua muaj zog, tsis tshua muaj alkalinity dej qhov chaw thiab ntxiv brewing ntsev rau mash thiab / los yog kettle.
Rau cov npias hoppier xws li American Pale Ale lossis American IPA, koj tuaj yeem ntxiv calcium sulfate (gypsum) rau hauv dej kom lub npias saj drier thiab muaj crisper, ntau assertive bitterness.Rau cov qauv maltier, xws li Oktoberfest lossis Brown Ale, koj tuaj yeem ntxiv calcium chloride rau hauv dej kom npias saj puv thiab qab zib.
Feem ntau, koj tsis xav kom ntau tshaj 400 ppm rau sulfate lossis 150 ppm rau chloride.Sulfate thiab chloride yog cov seasoning rau koj npias, thiab lawv qhov piv yuav cuam tshuam qhov tsw tshuav mus rau qib loj.Ib lub npias hoppy feem ntau yuav muaj sulfate-rau-chloride piv ntawm 3: 1 lossis siab dua, thiab koj tsis xav kom ob leeg nyob ntawm lawv qhov siab tshaj plaws vim tias qhov ntawd yuav ua rau npias saj zoo li dej ntxhia.
