Ni kofero ya screw mubyukuri?

Abantu benshi batekereza ko divayi ifunze hamwe na screw caps ihendutse kandi ntishobora kuba umusaza. Aya magambo arakwiriye?
1. Cork V. Guswera
Cork ikozwe mu gishishwa cy'igiti cork. Cork Oak ni ubwoko bwa oak ihingwa cyane cyane muri Porutugali, Espanye na Afurika y'Amajyaruguru. Cork nubushobozi buke, ariko bukora neza gukoresha, guhinduka no gukomera, bifite kashe nziza, kandi bituma ogisijeni yo kwinjira mu icupa, ifasha vino kugirango akomeze kwiteza imbere mu icupa. Ariko, vino zimwe zifunze na corks ni nyinshi kubyara trichloronanole (TCA), itera kwanduza cork. Nubwo kwanduza kristu bitagirira nabi umubiri wumuntu, impumuro nziza kandi uburyohe bwa divayi buzashira, isimburwa nimpumuro yikarito itose, izahindura uburyohe.
Bamwe mu bahinzi ba vino batangiye gukoresha ingofero mu 1950. Ingofero ya Screw ikozwe muri aluminium alloy na gasike imbere ikozwe muri polyethylene cyangwa tin. Ibikoresho byumugani bigena niba vino ari Anaerobic cyangwa iracyafite ogisijeni kwinjira. Utitaye ku bikoresho, ariko, intsinzi ya divayi yafashwe irahamye cyane kuruta divayi. Igishushanyo mbonera gifite icyiciro cyo hejuru kirenze cork, niko byoroshye kubyara reaction igabanuka, bikavamo impumuro yigi. Uru nirwo rubanza rwa dinone-ifunze ya cork.

Ingofero ya screw ikoreshwa cyane muri Ositaraliya na Nouvelle-Zélande, ariko ku rugero ruto muri Amerika n'ibihugu bishaje by'isi. 30% gusa bya divayi muri Amerika bifunze hamwe na kaps ya screw, kandi ni ukuri ko zimwe muri vino hano ntabwo ari nziza cyane. Nyamara kugeza kuri 90% bya divayi ya Nouvelle-Zélande birasenyutse, harimo vino yameza ihendutse, ariko kandi hamwe na vino nziza ya Nouvelle-Zélande. Kubwibyo, ntibishobora kuvugwa ko divayi ifite inzenga zihenze arihendutse kandi ifite ubuziranenge.
3. Irashobora gufunga hamwe na screw caps ntabwo ari umusaza?
Umushidikanya cyane abantu bafite ni ukumenya niba vino yashyizweho kashe ya screw ishobora gusaza. Hogue Cells i Washington, muri Amerika, yayoboye igeragezwa kugereranya ingaruka za Corks zisanzwe, amakarari na screw caps kuri divayi nziza. Ibisubizo byerekanye ko inzara zashizwemo impumuro nziza hamwe nuburyohe bwumutuku n'umweru wera. Ibikoni ndetse na kamere birashobora guteza ibibazo kuri okiside no kwanduza inkoko. Nyuma y'ibisubizo by'ubushakashatsi byasohotse, divayi zose zakozwe na Winery ya Hogg zahinduwe muri kaseke. Impamvu ituma gufunga cork nibyiza kuri vino gusa ni uko yemerera ogisijeni runaka kwinjira mu icupa. Uyu munsi, hamwe no guteza imbere ikoranabuhanga, inzitizi irashobora kandi kugenzura ingano ya ogisijeni yinjira neza ukurikije ibikoresho bya gakingi. Birashobora kugaragara ko imvugo ya divayi yashyizweho kashe hamwe na screw caps ntishobora kuba umusaza ntabwo yemewe.
Birumvikana ko kumva umwanya mugihe cork yafunguwe ari ikintu cyurukundo kandi cyiza. Ni ukubera kandi ko abaguzi bamwe bafite imyumvire ya oak bakanda, bameries nyinshi batinyuka gukoresha ingofero byoroshye nubwo bazi ibyiza byo kwicwa. Ariko, niba umunsi umwe watsinze ingofero ntagifatwa nkikimenyetso cya vino nziza, izakoresha imitsi mibi, kandi irashobora guhinduka ikintu cyurukundo kandi cyiza cyo gukuramo ingofero muri kiriya gihe!
