Xa uvula ibhotile yewayini endala kwaye wonganyelwe ngumbala wayo obomvu oqaqambileyo, ivumba elimnandi kunye nencasa egcweleyo, udla ngokuzibuza ukuba yintoni eyenza isipha seediliya eziqhelekileyo kule wayini ingenakuthelekiswa nanto?
Ukuphendula lo mbuzo, kufuneka siqale sicazulule ubume bomdiliya.
Iidiliya zineziqu, izikhumba, iibrashi, ipulp kunye nembewu.Amalungu ahlukeneyo aya kuzisa izinto ezahlukeneyo, umbala, i-tannin, utywala, i-asidi, incasa njalo njalo.
1. I-Tannin, i-color-peel
Izikhondo zomdiliya, amaxolo kunye nembewu yeyona mithombo ye tannins kwi wayini.
I-Tannin yinto yendalo ye-phenolic eyona mthombo oyintloko we-astringency kwiwayini.
Phakathi kwazo, i-tannins kwiziqu zeziqhamo zinoburhalarhume, ziqulethe iirasi ezikrakra kunye ne-tannic anhydrides.Ezi zinto zikholisa ukuvelisa i-astringency egqithisileyo kwiwayini, kwaye i-oyile ekrakra kwimbewu yomdiliya inokuchaphazela kakhulu incasa yewayini emva kokucinezela.Ngoko ke, iindawo ezininzi zewayini ziyakukhetha ukususa izikhondo zediliya ngexesha lenkqubo yevinification kwaye zizame ukucudisa imbewu yomdiliya kancinci kangangoko ngexesha lokucofa.Ezinye iindawo zewayini zikhetha ukugcina indawana yesikhondo ukuze ivundiswe.Iitannins ezisewayinini ziphuma ikakhulu kwiintsuba zediliya kunye nemiphanda ye-oki.I-tannins ilungile kwaye i-silika kwinkalakahla, kwaye yakha "i-skeleton" yewayini.
Ukongeza, incasa yewayini kunye nombala wewayini ebomvu iphuma ikakhulu ekutsalweni kweentsuba zeediliya ngexesha lokwenziwa kotywala.
2. Utywala, i-Acidity, iSiraphu
Ipulp yeziqhamo yeyona nto ibalulekileyo ekwenzeni iwayini.Isiraphu yomdiliya ityebile kwiswekile namanzi.Iswekile ivundiswe yigwele kwaye iguqulwa ibe yeyona nto ibalulekileyo kwiwayini - utywala.I-asidi kwi-pulp ikwayinxalenye ebalulekileyo, enokuthi igcinwe ngokuyinxenye ngexesha lenkqubo yokusela, ngoko ke iwayini ine-asidi ethile.
Ngokubanzi, imidiliya esuka kwimozulu epholileyo ine asidi ephezulu kunemidiliya evela kwimozulu eshushu.Ngomxholo weasidi yomdiliya, abavelisi bewayini nabo bongeza kwaye basuse iasidi ngexesha lenkqubo yokwenza iwayini.
Ngaphandle kotywala kunye neasidi, ubumnandi bewayini buphuma ikakhulu kwiswekile ekwipulp.
Abenzi bewayini balawula ubungakanani beswekile ekwiwayini ngokulawula inkqubo yokuvubela.Ngenxa yokuvubela okwaneleyo, isiqulatho seswekile yewayini eyomileyo sisezantsi kakhulu, ngelixa iwayini eswiti ikakhulu igcina inxenye yeglucose ngokunganelanga kokuvubela okanye yongeza incindi yencindi yomdiliya ukunyusa ubuswiti.
Iidiliya zisisiseko sewayini.Indawo nganye yomdiliya idlala indima ethile kwinkqubo yokwenza iwayini.Ukuphambuka kuyo nayiphi na indawo kunokukhokelela kwincasa yewayini, nto leyo ekhokelela ekubeni singcamle iiwayini ezininzi ezimnandi.
