Abantu abaningi bacabanga ukuthi iwayini elivalwe ngezikulufa ishibhile futhi awakwazi ukuguga. Ingabe lesi sitatimende silungile?
1. Ukhokho VS. Isikulufa Cap
Ukhokho wenziwa ngamagxolo e-oki kakhokho. I-Cork oak wuhlobo lwe-oki olutshalwa kakhulu ePortugal, eSpain naseNyakatho Afrika. I-Cork iyinsiza elinganiselwe, kodwa iyasebenza ukuyisebenzisa, iyaguquguquka futhi iqinile, inophawu oluhle, futhi ivumela inani elincane le-oxygen ukuthi lingene ebhodleleni, lisize iwayini ukuthi liqhubeke likhula ebhodleleni. Nokho, amanye amawayini avalwe ngokhokho athambekele ekukhiqizeni i-trichloroanisole (TCA), abangele ukungcoliswa kukakhokho. Nakuba ukungcoliswa kukakhokho kungeyona ingozi emzimbeni womuntu, iphunga nephunga lewayini liyoshabalala, esikhundleni salo kube nephunga elibi lebhokisi elimanzi, elizothinta ukunambitheka.
Abanye abakhiqizi bewayini baqala ukusebenzisa ama-screw caps ngawo-1950s. I-screw cap yenziwe nge-aluminium alloy kanti i-gasket ngaphakathi yenziwe nge-polyethylene noma ithini. Impahla ye-liner inquma ukuthi iwayini liyi-anaerobic ngokuphelele noma lisavumela umoya-mpilo othile ukuthi ungene. Noma ngabe imuphi umkhiqizo, kodwa-ke, amawayini afakwe isikulufa azinzile kunamawayini amakhokho ngoba ayikho inkinga yokungcoliswa kukakhokho. I-screw cap inezinga eliphezulu lokuvala kunokhokho, ngakho-ke kulula ukukhiqiza ukusabela kokunciphisa, okuholela ephunga lamaqanda abolile. Lokhu kunjalo nangewayini elivalwe ngokhokho.
2. Ingabe amawayini ane-screw caped ashibhile futhi awekhwalithi embi?
Ama-screw caps asetshenziswa kakhulu e-Australia naseNew Zealand, kodwa kancane e-United States namazwe oMhlaba Omdala. Amaphesenti angama-30 kuphela amawayini e-United States avaliwe ngezikulufu, futhi kuyiqiniso ukuthi amanye amawayini lapha awamahle kakhulu. Nokho kufike ku-90% wamawayini aseNew Zealand ane-screw capped, okuhlanganisa namawayini etafula ashibhile, kodwa namanye amawayini ahamba phambili aseNew Zealand. Ngakho-ke, ngeke kushiwo ukuthi amawayini anama-screw caps ashibhile futhi anekhwalithi ephansi.
3. Ingabe iwayini elivalwe ngezikulufa ngeke liguge?
Ukungabaza okukhulu abantu abanako ukuthi amawayini avalwe ngezikulufa angaguga yini. I-Hogue Cellars e-Washington, e-U.S.A., yenza ucwaningo lokuqhathanisa imiphumela yamakhokho emvelo, okhokho bokwenziwa kanye nama-screw caps kwikhwalithi yewayini. Imiphumela yabonisa ukuthi ama-screw caps agcina iphunga elimnandi nephunga elimnandi lamawayini abomvu namhlophe. Kokubili ukhokho wokwenziwa nowemvelo ungabangela izinkinga nge-oxidation nokungcoliswa kukakhokho. Ngemuva kokuphuma kwemiphumela yocwaningo, wonke amawayini akhiqizwa yi-Hogg Winery ashintshelwa kuma-screw cap. Isizathu sokuthi ukuvalwa kukakhokho kuhle ekugugeni kwewayini ukuthi kuvumela inani elithile le-oxygen ukuthi lingene ebhodleleni. Namuhla, ngokuthuthuka kobuchwepheshe, ama-screw caps angakwazi futhi ukulawula inani le-oxygen engena ngokunembe ngokwezinto ze-gasket. Kuyabonakala ukuthi isitatimende sokuthi amawayini avalwe ngezikulufa ngeke aguge asivumelekile.
Yiqiniso, ukulalela isikhathi lapho ukhokho evuliwe kuyinto enothando kakhulu futhi enhle kakhulu. Yingoba abanye abathengi banomuzwa wesitobha se-oki, abakhiqizi abaningi bewayini abalokothi basebenzise amakepisi ngezikulufu kalula ngisho noma bezazi izinzuzo zamakepisi esikulufa. Kodwa-ke, uma ngolunye usuku ama-screw caps engasabhekwa njengophawu lwamawayini ekhwalithi ephansi, izitolo eziningi zewayini zizosebenzisa ama-screw caps, futhi kungase kube yinto yothando nenhle ukuqaqa isikulufu se-screw cap ngaleso sikhathi!
