Abantu abaninzi bacinga ukuba iiwayini ezitywinwe ngeescrew cap zinexabiso eliphantsi kwaye azinakukhula. Ngaba le ngxelo ichanekile?
1. Isikhokho VS. Screw Cap
Isikhokho senziwe kwixolo le-oki. I-Cork oak luhlobo lwe-oki olulinywa kakhulu ePortugal, eSpain nakuMntla Afrika. I-Cork isisityebi esilinganiselweyo, kodwa sisebenza ngokufanelekileyo, siguquguqukayo kwaye sinamandla, sinetywina elihle, kwaye sivumela i-oksijini encinci ukuba ingene kwibhotile, inceda iwayini ukuba iqhubeke nokuphuhlisa kwibhotile. Nangona kunjalo, ezinye iiwayini ezitywinwe ngeecorks zidla ngokuvelisa i-trichloroanisole (TCA), ebangela ukungcoliseka kwezikhonkwane. Nangona ungcoliseko lwezikhokho lungenabungozi emzimbeni womntu, ivumba elimnandi kunye nencasa ye wayini iyakunyamalala, endaweni yayo livumba lobumdaka lebhokisi emanzi, eliya kuchaphazela incasa.
Abanye abavelisi bewayini baqala ukusebenzisa izikrufu iikepusi ngoo1950s. I-screw cap yenziwe nge-aluminium alloy kwaye i-gasket ngaphakathi yenziwe nge-polyethylene okanye i-tin. Izinto zeliner zigqiba ukuba iwayini i-anaerobic ngokupheleleyo okanye isavumela ioksijini ukuba ingene. Nokuba yeyiphi na imathiriyeli, nangona kunjalo, iiwayini ze-screw capped zizinzile kunewayini ezinkonkxiweyo kuba akukho ngxaki yongcoliseko lwe-cork. I-screw cap ineqondo eliphezulu lokutywinwa kune-cork, ngoko kulula ukuvelisa ukusabela kokunciphisa, okukhokelela kwivumba lamaqanda abolileyo. Kukwanjalo nakwiwayini ezitywiniweyo zecork.
2. Ingaba iiwayini ezifakwe kwi-screw cap zitshiphu kwaye zikumgangatho ophantsi?
I-Screw caps isetyenziswa kakhulu e-Australia naseNew Zealand, kodwa kwinqanaba elingaphantsi e-United States kunye namazwe asehlabathini elidala. Kuphela yi-30% yewayini e-United States etywinwe ngee-screw caps, kwaye yinyani ukuba ezinye zewayini apha azilungile kakhulu. Kodwa ukuya kuthi ga kwi-90% yewayini zaseNew Zealand zifakwe isikrufu, kubandakanywa newayini zetafile ezinexabiso eliphantsi, kodwa nezinye zezona wayini zaseNew Zealand. Ngoko ke, akunakutshiwo ukuba iwayini ezineekepusi ze-screw zitshiphu kwaye zikumgangatho ophantsi.
3. Ingaba iiwayini ezitywinwe ngeescrew cap azigugi?
Owona mathandabuzo amakhulu abantu abanawo kukuba ingaba iiwayini ezitywinwe ngezikhonkwane zingaguga na. IHogue Cellars yaseWashington, eU.SA, yenze ulingo lokuthelekisa iziphumo zezikhonkwane zendalo, izikhonkwane ezenziweyo kunye nezikrufu iikepusi kumgangatho wewayini. Iziphumo zabonisa ukuba i-screw caps zigcina ivumba leziqhamo kunye nencasa zewayini ezibomvu nezimhlophe kakuhle. Zombini i-cork yokwenziwa kunye neyendalo inokubangela iingxaki nge-oxidation kunye nokungcoliswa kwe-cork. Emva kokuba iziphumo zovavanyo ziphumile, zonke iiwayini eziveliswe yiHogg Winery zatshintshelwa kwizikrufu. Isizathu sokuba ukuvalwa kwe-cork kukulungele ukuguga kwewayini kukuba ivumela inani elithile le-oksijini ukuba lingene ebhotileni. Namhlanje, ngokuhambela phambili kwetekhnoloji, ii-screw caps zinokulawula ubungakanani beoksijini engena ngokuchanekileyo ngokwezinto zegasket. Ingabonwa into yokuba ingxelo yokuba iwayini ezitywinwe ngezikrufu iikepusi azinakuguga ayisebenzi.
Ngokuqinisekileyo, ukumamela umzuzu xa i-cork ivuliwe yinto enothando kakhulu kunye nenhle. Kukwangenxa yokuba abanye abathengi banemvakalelo yesithinteli se-oki, iindawo ezininzi zewayini azibi nabuganga bakusebenzisa izikhonkwane ezisikrufu ngokulula nokuba ziyazazi izibonelelo zezikrufu. Nangona kunjalo, ukuba ngenye imini ii-screw caps azisajongwa njengophawu lwewayini ekumgangatho ophantsi, ii-wineries ezininzi ziya kusebenzisa ii-screw caps, kwaye inokuba yinto yothando nenhle ukukhulula isikrufu se-screw cap ngelo xesha!
