Kev npaj cov dej cawv yog tsis yooj yim sua yam tsis muaj lub thawv tshwj xeeb uas fermentation tshwm sim. Nyob rau hauv ntau txoj kev, saj nyob ntawm lub peev xwm, yog li kev xaiv yuav tsum tau mus cuag lub luag hauj lwm. Peb yuav saib qhov zoo thiab qhov tsis zoo ntawm ntau hom fermentation hlab ntsha.
Thaum xaiv lub thawv tsim nyog, lub tsev distiller yuav siv peb qhov tseem ceeb: cov khoom siv, ntim thiab nruj.
1. Khoom
Lub thawv fermentation yuav tsum tsis txhob yog hlau, vim cov hlau oxidizes ntawm kev sib cuag nrog wort thiab spoils cov dej haus. Rau tib lub laj thawj, txhuas cov kaus poom mis nyuj tsis haum, lawv tsuas yog siv tau los ua ib qho tseem, txij li thaum lub sij hawm distillation lub sij hawm sib cuag ntawm txhuas thiab mash yog qhov tseem ceeb.
Cov iav fwj, lub raj mis dej haus thiab cov khoom noj tshwj xeeb-qib yas ntim tau suav tias yog qhov kev xaiv zoo tshaj plaws. Nws tseem tuaj yeem siv cov thawv tsis muaj steel hlau thiab cov thawv ntoo.
Qhov zoo ntawm cov ntim iav yog nyob rau hauv cov tshuaj tsis zoo ntawm cov khoom (tsis tuaj yeem cuam tshuam nrog cawv thiab lwm yam tshuaj) thiab pob tshab - koj tuaj yeem pom los ntawm cov phab ntsa dab tsi tshwm sim nrog wort tam sim no. Qhov tsis zoo ntawm cov iav ntim yog tias lawv tsis yooj yim heev, hnyav thiab tsis xis nyob nrog lub ntim loj, raug tshav ntuj ncaj qha. Txawm li cas los xij, iav yog qhov kev xaiv zoo tshaj plaws rau lub tsev fermentation tank.
Cov thawv ntim khoom noj yog qhov nruab nrab ntawm qhov chaw acidic ntawm qhov yuav tsum tau, tsis txhob cuam tshuam nrog cawv (yog tias lub zog qis dua 15%), pheej yig, ruaj thiab lub teeb, thiab lub raj mis rau cov dej haus kuj yog pob tshab. Qhov tsis zoo yog tias cov yas tsis zoo tso tawm cov khoom tsis zoo rau hauv cov mash, uas tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv, hloov cov saj thiab tsis hnov tsw ntawm cov dej haus. Ntau thiab ntau lub thawv yas tshwj xeeb rau fermentation tshwm sim ntawm kev muag khoom, uas maj mam kov yeej lub khw. Novice distillers feem ntau muab mash thiab cawv rau hauv lub raj mis rau cov dej haus, nrog rau cov khoom zoo li qub tsis muaj teeb meem.
Nco ntsoov! Nws tsis pom zoo kom khaws cawv hauv cov yas (tej zaum yuav ua rau cov khoom organoleptic deterioration), thiab yog tias lub zog ntawm cov dej haus siab dua 15%, feem ntau yog txwv tsis pub.
Stainless hlau tso tsheb hlau luam yog txhim khu kev qha, ruaj, nruab nrab rau cawv thiab acids nyob rau hauv lub wort, tab sis loj, hnyav, kim thiab opaque. Feem ntau cov khoom siv no yog siv rau kev lag luam fermentation tso tsheb hlau luam lossis los ntawm cov kws paub txog distillers uas txaus siab los nqis peev hauv cov khoom siv.
Ntoo tej kas tham thiab tej thoob yog zoo haum rau caw fermentation - lawv khaws qhov kub thiab tiv thaiv qhov yuav tsum tau los ntawm tshav ntuj. Qhov tsis zoo ntawm cov ntoo kegs yog tias lawv kim thiab lawv yuav tsum tau ntxuav kom huv si tom qab txhua lub voj voog brewing.
2. Volume
Feem ntau cov iav fwj muaj qhov ntim ntawm 10 lossis 20 litres, thiab yas - 6-60 litres. Cov thawv ntoo tuaj hauv 10, 20, 30 lossis ntau dua litres.
Thaum xaiv lub thawv rau fermentation, koj yuav tsum nco ntsoov tias cov mash los yog cawv yuav tsum tsis pub ntau tshaj 75% ntawm lub ntim, txwv tsis pub tej zaum yuav muaj teeb meem nrog ua npuas ncauj thiab carbon dioxide tshem tawm.
3. Ceev ceev
Lub thawv yuav tsum tau zoo, tsis muaj kab nrib pleb thiab chips. Ib qho kev zam me me tsuas yog ua rau cov thawv ntoo xwb, lawv me ntsis cia cua los ntawm qhov hws, tab sis qhov no tsis cuam tshuam rau qhov zoo ntawm cov dej haus tiav.
Thaum yuav khoom, nws raug nquahu kom xaiv lub thawv rau hauv lub caj dab lossis lub hau uas lub foob dej ua rau hauv, lossis tsawg kawg yog muaj qhov chaw rau nruab, ces koj tsis tas yuav tho, foob thiab nplaum dab tsi.
