Txhua tus ntsuj plig mus txog tsawg kawg yog ob txoj kev - fermentation thiab distillation. Fermentation yog qhov twg tag nrho cov cawv raug tsim, distillation yog qhov twg cov cawv raug cais thiab tshem tawm. Yuav kom fermentation tshwm sim, ob yam yuav tsum tau: ib tug raw cov ntaub ntawv nyob rau hauv kua daim ntawv uas muaj suab thaj, tom qab ntawd ntxiv cov poov xab. Cov poov xab yog cov kab mob muaj sia uas pub cov piam thaj; bi-cov khoom ntawm kev noj no yog cawv thiab carbon dioxide (CO2).
Ib qho yooj yim formula rau fermentation yog:
YEAST + SUGAR=ALCOHOL + C02
Distilling yog qhov tseem ceeb ntawm cov txheej txheem uas yog cov kua ua los ntawm ob lossis ntau qhov chaw tau muab cais ua qhov me me ntawm qhov xav tau purity los ntawm qhov sib ntxiv thiab rho tawm ntawm tshav kub los ntawm qhov sib tov. Cov vapors / kua distilled yuav cais lwm cov khoom xyaw uas muaj cov ntsiab lus qis dua. Distilled ntsuj plig yog tsim los ntawm kev ua liaj ua teb raw khoom xws li txiv hmab txiv ntoo, lwm yam txiv hmab txiv ntoo, qab zib-cane, molasses, qos yaj ywm, cereals, thiab lwm yam.
