Caw tau khaws cia rau hauv lub khob iav rau ntau yam laj thawj. iav yog ib yam khoom uas tsis yog-reactive uas tsis cuam tshuam nrog cov cawv, kom ntseeg tau tias nws thawj saj thiab aroma yog khaws cia. Tsis tas li ntawd, iav muaj lub siab transparency, tso cai rau cov cawv txiv hmab cov xim thiab zoo kom pom tau yooj yim thiab txaus siab rau.
Cov iav fwj kuj muaj qhov zoo ntawm kev tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev tawg lossis tawg. Qhov no ua rau lawv haum rau khaws cia cawv thaum lub sij hawm fermentation thiab aging txheej txheem, thaum kub hloov pauv ntau. Cov khoom siv iav kuj tseem muaj kev thaiv kev tiv thaiv lub teeb pom kev, uas tuaj yeem ua mob rau cov cawv txiv hmab zoo yog tias nws khaws cia rau hauv tshav ntuj ncaj qha.
Tsis tas li ntawd, iav muaj qhov tsawg ntawm cov pa permeability, uas txhais tau hais tias nws tuaj yeem tiv thaiv cov cawv los ntawm oxidation, txheej txheem uas tuaj yeem hloov nws qhov tsw thiab xim. Hauv qhov sib piv, cov ntaub ntawv zoo li yas, uas feem ntau siv los khaws lwm hom kua, tsis haum rau kev cia cawv vim lawv muaj peev xwm tso lub teeb thiab oxygen rau hauv lub thawv.

Hauv kev xaus, cawv yog khaws cia rau hauv lub khob iav vim nws cov khoom tsis muaj zog, siab transparency, muaj peev xwm tiv taus qhov kub thiab txias thiab tiv thaiv cov cawv los ntawm lub teeb thiab oxygen. Iav kuj yog cov khoom ntim khoom noj khoom haus uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo uas tuaj yeem siv tau yooj yim thiab rov siv dua.
