Vim li cas lub plawv txiav cov txheej txheem sib txawv thiab yog vim li cas whiskey hom ntawm The Macallan thiab Glenfiddich thiaj li txawv?
Peb tau hais ua ntej tias Glenfiddich Distillery thiab Macallan Distillery yog ob qho tib si nyob hauv thaj chaw tsim khoom Speyside. Qhov luaj li cas ntawm qhov tseem ceeb tsis txawv ntau, tab sis vim muaj cov txheej txheem sib txawv rau kev txiav tawm tus ntsuj plig, cov whiskey yeej ntawm ob qhov sib txawv heev. , Macallan whiskey yog nplua nuj thiab tag nrho, thaum Glenfiddich whiskey kuj tseem tshiab.
Vim li cas cov txheej txheem "Caw core interception" muaj qhov cuam tshuam loj?
Ua ntej tshaj plaws, peb yuav tsum nkag siab tias yog vim li cas peb thiaj li yuav tsum tau ua "kev cuam tshuam lub plawv cawv".
Distillation
Malt whiskey distilled siv lub lauj kaub tseem feem ntau yuav tsum tau ob distillation. Thawj yog mash distillation, tseem hu ua thawj distillation. Nws yog distilled cov fermented mash kom rho tawm cov ethanol thiab lwm yam kab mob. Cov ntsiab lus cawv yog li 8 degrees. Tom qab distillation ntawm mash, feem ntau koj yuav tau txais ib tug distilled caw ntawm txog 23 degrees. Peb paub tias cov kev cai lij choj thiab cov kev cai ntawm Scotch whiskey xav kom cov cawv ntawm cov kua txiv hmab txiv ntoo tshiab yuav tsum qis dua 94.8 degrees. Nyob rau tib lub sijhawm, cov ntsiab lus cawv ntawm cov khoom lag luam Scotch whiskey feem ntau yog 40 degrees lossis 43 degrees. Thawj distilled cawv nrog 23 degrees yog deb ntawm ob qhov yuav tsum tau ua. Qhov sib txawv yog loj heev, yog li thawj distilled cawv yuav tsum tau distilled ob zaug. Cov txheej txheem no yog hu ua ntsuj plig distillation, uas txhais tau hais tias kom ntxuav cov cawv thawj zaug thiab ua kom cov cawv ntau ntxiv.
Tom qab tus ntsuj plig distillation txheej txheem, cov khoom distilled tau txais tau theoretically raug sau rau kev laus. Txawm li cas los, fermentation yog ib tug complex txheej txheem. Ntxiv nrog rau ethanol thiab ntau cov khoom xyaw uas ua rau kom tsw qab, cov khoom lag luam kuj suav nrog qee cov khoom xyaw uas tsim kev puas tsuaj rau tib neeg lub cev, xws li methanol, yuav ua rau muaj kev phom sij rau lub cev yog tias sau tag nrho. Hmoov zoo, cov ntsiab lus boiling thiab volatility ntawm cov tshuaj no txawv ntawm ethanol. Yog li ntawd, raws li cov yam ntxwv no, cov khoom uas muaj cov ntsiab lus siab ntawm cov khoom tsis zoo tuaj yeem raug tshem tawm, thiab cov khoom uas muaj cov ntsiab lus tsis zoo ntawm cov khoom tsis zoo tuaj yeem cuam tshuam raws li cov cawv tshiab. Qhov no yog qhov hu ua "wine interception".
Feem ntau hais lus, methanol, acetone thiab lwm yam khoom uas tsim kev puas tsuaj rau tib neeg lub cev yog volatile thiab muaj ib tug qis boiling point, yog li cov methanol, acetaldehyde, ethyl formate, acetone, thiab lwm yam nyob rau hauv lub "lub taub hau" ntawm cov cawv txiv hmab uas nyuam qhuav. tau distilled yog Cov ntsiab lus kuj siab, yog li qhov no yuav tsum tau muab cais thaum noj cov cawv. Thaum lub distillation yuav xaus, lub cev cawv yuav muaj ntau fatty acids, fusel roj thiab sulfides. Qhov no ntawm lub cev cawv yog "wine tail" thiab yuav tsum tau muab cais. Lub cev tau txais los ntawm distilling nruab nrab ib feem ntawm cov cawv txiv hmab yog "lub plawv", uas yog ib feem ntawm cov cawv txiv hmab uas muaj kuj tsawg theem ntawm teeb meem tshuaj.
Ntsuj plig taub hau
Raws li tuaj yeem pom los ntawm cov lus piav qhia saum toj no, "wine head", "wine heart" thiab "wine tail" yog cov ntsiab lus txheeb ze, thiab tsis muaj cov qauv qhia meej meej. Kev faib tawm feem ntau yog raws li cov distillery cov cai rau lub cev thiab tsw ntawm cawv. Lub cev cawv nyob rau hauv nruab nrab ib feem ntawm lub distillation yog kuj "ntxuav", yog li qhov qis dua "lub plawv cuam tshuam" piv, lub cev lub cev huv si. Tsis tas li ntawd, qhov ceev ntawm distillation kuj cuam tshuam qhov tsw ntawm whiskey. Qhov ceev ntawm distillation ceev, lub sij hawm ntev kom tshem tawm "lub plawv" ntawm cov cawv txiv hmab, lub cev ntxuav lub cev. Qhov ceev ntawm qhov dej ntws nrawm, lub sijhawm luv dua kom tshem tawm "lub siab" ntawm cawv. Lub cev ua ntau nyuaj.
Rov qab mus rau thawj lo lus nug, ib qho laj thawj tseem ceeb vim li cas Macallan whiskey nplua nuj thiab tag nrho, thaum Glenfiddich whiskey refreshing yog qhov sib txawv ntawm lub sij hawm nws yuav siv sij hawm tshem tawm lub plawv ntawm cawv vim qhov ceev ntawm distillation. Lub sijhawm nws siv rau Macallan kom tshem tawm lub plawv ntawm cawv yog li 70 feeb, Glenfiddich siv sijhawm ntau tshaj li ob teev kom tau "lub siab" ntawm cov cawv.
Yuav ua li cas paub qhov txawv "lub taub hau", "lub siab" thiab "tail" nyob rau hauv qhov tseeb distillation? Ib qho yooj yim thiab yooj yim-rau-paub qhov sib txawv ntawm "lub taub hau", "lub siab" thiab "tail" yog cov ntsiab lus cawv sib txawv. Cov ntsiab lus cawv ntawm "lub taub hau" yog li 72 degrees lossis ntau dua, thiab cov ntsiab lus cawv ntawm "lub siab" yog li 68 ~ 72 degrees. Nyob nruab nrab ntawm cov degrees, cov ntsiab lus cawv ntawm "wine tail" yog hais txog qis dua 60 degrees, uas tuaj yeem ntsuas thiab suav nrog siv lub ntsuas cawv.
Nyob rau hauv nruab nrab txee yog qhov kev nyab xeeb
Koj qhia qhov txawv li cas ua ntej muaj lub ntsuas dej cawv? Kev lag luam cawv hauv Suav teb muaj cov txheej txheem "saib paj thiab khaws cov cawv", uas yog txiav txim siab "lub taub hau", "lub siab" thiab "tail" ntawm cov cawv raws li lub hops thaum khaws cov cawv. Hauv kev lag luam whiskey, "defog test" yog siv los txiav txim rau "lub taub hau". Muaj ntau cov tshuaj lipid hauv "lub taub hau". Ntxiv dej rau qhov chaw nyab xeeb kom dilute cov cawv mus rau 45.7 degrees. Lub sijhawm no, cov cawv yuav dhau los ua Turbid, thaum "lub taub hau" dhau lawm, cov cawv yuav maj mam ua kom meej. Nws tau hais tias "wine tail" yuav tig xiav thaum dej ntxiv (tus sau tsis tau pom qhov no. Lub hauv paus ntsiab lus yog tias cov sulfur hauv cov cawv txiv hmab reacts nrog tooj liab ntawm lub lauj kaub tseem thaum lub sij hawm distillation los tsim tooj liab sulfate. Tom qab ntxiv dej, tooj liab sulfate yuav nyob rau hauv cov kua dej crystallizes los tsim xiav tooj liab sulfate pentahydrate Yav tas los, thaum peb sim nrog distilled malt whiskey, peb tuaj yeem pom xiav tooj liab sulfate pentahydrate blocks hauv "tail".
Tail
Los ntawm txoj kev, txawm hais tias tsuas yog "lub siab" yog muab los ntawm cov cawv tshiab, nws tsis txhais hais tias "lub taub hau" thiab "tails" yuav raug muab pov tseg. Cov txheej txheem distillation yog yeej tsis nkim. Lub intercepted "heads" thiab "tails" Lub "tails" yog ntxiv rau tom ntej no batch ntawm mash thiab distilled dua.
