Qhov no tshwm sim nyob rau hauv kev cuam tshuam ntawm cov enzymes secreted los ntawm poov xab, thiab qhov tseeb yog txheej txheem txheeb raws roj ntsha nrog kev tso tawm ntawm tshav kub, cov mis uas tau qhia ntxov li 1810 los ntawm Gay-Lussac

- Ntawm caw liab fermentation nws tuaj yeem tshwm sim ob qho tib si thaum cov txiv hmab nrog nrog cov ntses thiab thaum nws tsis muaj. Yog tias nws nrog cov xyoob ntoo, nws yuav ntau dua vim tias cov tannins, thaum yog tias tsis muaj lawv - nws kis tau saj softer;

Txawm li cas los xij, feem ntau cov neeg tsim khoom cawv ua nws nyob rau ntawm 18 degrees kom thiaj li muaj kev tswj hwm tag nrho nws cov aroma.
