Anthu ambiri amaganiza kuti mavinyo omata ndi zipewa ndi zotsika mtengo ndipo sangakalamba. Kodi mawu awa ndi olondola?
1. Nkhata VS. Screw Cap
Nkhata Bay imapangidwa kuchokera ku khungwa la cork oak. Cork oak ndi mtundu wa oak womwe umalimidwa makamaka ku Portugal, Spain ndi kumpoto kwa Africa. Cork ndi gwero laling'ono, koma ndi losavuta kugwiritsa ntchito, losinthasintha komanso lolimba, limakhala ndi chisindikizo chabwino, ndipo limalola kuti mpweya wochepa ulowe mu botolo, zomwe zimathandiza kuti vinyo apitirize kukula mu botolo. Komabe, mavinyo ena osindikizidwa ndi corks amakonda kutulutsa trichloroanisole (TCA), zomwe zimapangitsa kuti nkhokwe ziipitsidwe. Ngakhale kuipitsidwa kwa cork sikuvulaza thupi la munthu, fungo ndi kukoma kwa vinyo zidzatha, m'malo mwa fungo la musty la katoni yonyowa, yomwe idzakhudza kukoma kwake.
Opanga vinyo ena adayamba kugwiritsa ntchito zipewa za 1950s. Chophimbacho chimapangidwa ndi aluminiyamu alloy ndipo gasket mkati mwake imapangidwa ndi polyethylene kapena malata. Zinthu za mpanda zimatsimikizira ngati vinyo ali anaerobic kwathunthu kapena amalola kuti mpweya wina ulowe. Mosasamala kanthu za zinthu, komabe, mavinyo opindika amakhala okhazikika kuposa mavinyo okhala ndi zikhomo chifukwa palibe vuto lakuipitsidwa ndi kokwa. Chotchinga chotchinga chimakhala ndi digiri yayikulu yosindikizira kuposa chimango, kotero ndizosavuta kutulutsa zomwe zimapangitsa kuti pakhale fungo la mazira owola. Izi ndizochitikanso ndi mavinyo otsekedwa ndi kork.
2. Kodi mavinyo opangidwa ndi screw caped ndi otsika mtengo komanso osawoneka bwino?
Zipewa za screw zimagwiritsidwa ntchito kwambiri ku Australia ndi New Zealand, koma pang'ono ku United States ndi mayiko a Old World. Mavinyo 30 pa 100 alionse ku United States amamata ndi zipewa, ndipo n’zoona kuti vinyo wina pano si wabwino kwambiri. Komabe mpaka 90% ya vinyo waku New Zealand ndi wopindika, kuphatikiza mavinyo otsika mtengo, komanso vinyo wabwino kwambiri ku New Zealand. Chifukwa chake, sizinganenedwe kuti mavinyo okhala ndi zisonga zomata ndi otsika mtengo komanso osawoneka bwino.
3. Kodi mavinyo omata ndi zomata sangakalamba?
Chikaiko chachikulu chomwe anthu amakhala nacho ndikuti ngati mavinyo osindikizidwa ndi zisonga amatha kukalamba. A Hogue Cellars ku Washington, USA, adayesa kuyerekeza zotsatira za corks zachilengedwe, zopangira zopangira ndi zipewa zomangira vinyo pamtundu wa vinyo. Zotsatira zake zidawonetsa kuti ma screw caps amasunga fungo labwino komanso kukoma kwa vinyo wofiira ndi woyera bwino. Nkhata zopanga komanso zachilengedwe zimatha kuyambitsa mavuto ndi makutidwe ndi okosijeni komanso kuipitsidwa ndi kork. Zotsatira za kuyesako zitatuluka, mavinyo onse opangidwa ndi Hogg Winery adasinthidwa kukhala ma screw caps. Chifukwa chomwe kutsekedwa kwa nkhono ndikwabwino ku ukalamba wa vinyo ndikuti amalola kuti mpweya wochuluka ulowe mu botolo. Masiku ano, ndi kupita patsogolo kwaukadaulo, ma screw caps amathanso kuwongolera kuchuluka kwa okosijeni omwe amalowa bwino kwambiri malinga ndi zomwe gasketyo. Zitha kuwoneka kuti mawu oti mavinyo osindikizidwa ndi zisoti zomata sangakhale okalamba sizolondola.
Inde, kumvetsera nthawi yomwe cork ikutsegulidwa ndi chinthu chokonda kwambiri komanso chokongola. Zilinso chifukwa ogula ena amamva ngati choyimitsa oak, ma wineries ambiri sayesa kugwiritsa ntchito zisoti zomangira mosavuta ngakhale akudziwa zabwino za zisoti. Komabe, ngati tsiku lina zisonga zomangira sizikuganiziridwanso ngati chizindikiro cha vinyo wosauka, ma wineries ambiri adzagwiritsa ntchito zisoti zomangira, ndipo chingakhale chinthu chachikondi komanso chokongola kumasula kapu ya screw panthawiyo!
