Ib qho tseem ceeb ntawm kev tsim cov whiskey yog distillation. Distillation yog qhov ua tau ntawm kev rho tawm ethanol thiab cov kab hauv cov mash los ntawm cua sov. Qhov loj thiab cov duab ntawm qhov tseem thaum lub sij hawm distillation, thiab lub sij hawm ntawm kev txiav lub plawv ntawm cawu cub yuav tag nrho cov cuam tshuam lub tsw ntawm whiskey. Tsis tas li ntawd, cov txheej txheem cua sov thaum lub sij hawm distillation tseem yuav cuam tshuam qhov tsw ntawm whiskey.

Nyob rau hauv ancient sij hawm, tib neeg teeb hluav taws nyob rau hauv lub tseem kom ncaj qha tshav kub, zoo li lub qhov cub taws nyob rau hauv cov cheeb tsam nyob deb nroog. Txoj kev no hu ua "direct fire heating". Cov roj uas siv thaum ntxov yog ntoo, thee, peat, thiab lwm yam, thiab tom qab ntawd feem ntau yog hloov mus rau natural gas.
Nyob ib ncig ntawm 1960s, feem ntau distilleries tsis tau siv "qhov hluav taws kub ncaj qha" thiab hloov mus rau "indirect heating" (thawj lub tuam txhab siv cov txheej txheem "indirect heating" yog Glenmorangie, uas yog 1887). Feem ntau "indirect cua sov" yog "kub indirect cua sov", uas yog, ib tug chav dej yog ntsia nyob rau hauv los yog sab nraum lub distiller, lub hauv paus boiler yog siv los ua cua sov dej los tsim cov chav, thiab ces cov chav yog thauj mus rau lub chav dej. los pauv cov cua sov nrog rau sab hauv ntawm lub distiller. Kub lub sake mash. Tsis tas li ntawd, muaj "dej da dej cua sov". Raws li lub npe qhia, hauv qab ntawm lub distiller yog muab tso rau hauv dej kub rau cua sov, zoo li ua noj ua haus. Niaj hnub no, feem ntau Scottish distilleries siv "indirect cua sov". Tsuas yog peb lub distilleries, Glenfarclas, Glenfiddich thiab Springbank, tseem siv "qhov hluav taws kub ncaj qha". Ntau lub distilleries hauv Nyij Pooj tseem tuav cov txheej txheem "tsim hluav taws xob ncaj qha".

Vim li cas feem ntau distilleries tsis siv "qhov hluav taws kub ncaj qha"? Yog vim li cas yog tias "qhov hluav taws kub ncaj qha" yog kim thiab nyuaj rau kev khiav lag luam. Thaum siv cov txheej txheem "qhov hluav taws kub ncaj qha", qhov tseem yuav tsum tau tiv taus hluav taws kub, thiab lub lauj kaub phab ntsa yuav tsum thicker. Lub phab ntsa ntawm "qhov hluav taws kub ncaj qha" tseem yuav yog 10mm tuab dua li "indirect cua sov" tseem; thiab cov distilled mash Nws yog mushy thiab yooj yim sticks rau hauv qab thiab sab hauv phab ntsa ntawm lub distillation kettle thaum rhuab los ntawm hluav taws ncaj qha. Yog li ntawd, ib tug scraper yuav tsum tau ntsia nyob rau hauv lub distillation kettle siv cov txheej txheem "direct hluav taws kub" rau scrape tawm cov hmoov txhuv nplej siab nyob rau hauv lub puab phab ntsa. Thaum khawb tawm cov hmoov txhuv nplej siab, nws yog ib qho tseem ceeb uas cov tooj liab ntawm lub lauj kaub tseem yuav raug muab pov tseg, yog li kev noj ntawm lub lauj kaub tseem yuav loj. Tsis tas li ntawd, yog tias qhov "qhov hluav taws kub hluav taws xob ncaj qha" tsis tswj xyuas kom zoo, cov hmoov txhuv nplej siab daig rau sab hauv phab ntsa ntawm lub lauj kaub distillation yuav raug hlawv, uas yuav ua rau cov cawv txiv hmab tsis sib haum xeeb.

Tsis yog "qhov hluav taws kub ncaj qha" tsis muaj qhov zoo? tsis muaj. "Direct hluav taws kub cua sov" tuaj yeem ncav cuag qhov kub siab dua. Nws tau hais tias qhov kub ntawm "qhov hluav taws kub ncaj qha" tuaj yeem ncav cuag ntau dua 650 degree, thaum cua sov tsis ncaj tuaj yeem ncav cuag 130 degree. Ib tug series ntawm complex tshuaj yuav tshwm sim thaum lub sij hawm kub kub (xws li "virtue" Pull cov tshuaj tiv thaiv", uas yuav tsim lub flavors ntawm chocolate thiab caramel), muab cov thawj cawu cub nrog complex flavors ntawm caramel, chocolate, txiv ntseej, thiab lwm yam. hais lus, whiskey uas siv cov txheej txheem "qhov hluav taws kub ncaj qha" feem ntau muaj "hnyav lub cev" thiab qhov nyuaj, nplua nuj tsw Vim li no, cov khoom siv hluav taws xob uas xav kom muaj cov tshuaj tsw qab tseem siv "cov hluav taws kub hluav taws xob ncaj qha" Cov piv txwv zoo tshaj plaws. thev naus laus zis yog Glenfarclas Xyoo 1981, Glenfarclas tau hloov "qhov hluav taws kub ncaj qha" mus rau "kub cua sov". mus rau "direct heat".
