Ese koko imipira ya kaburimbo ni mbi?

Abantu benshi batekereza ko divayi ifunze hamwe na capit ya screw ihendutse kandi ntishobora gusaza. Aya magambo arukuri?
1. Cork VS. Igikoresho
Cork ikozwe mubishishwa by'igiti cya cork. Igiti cya Cork ni ubwoko bw'igiti cyahinzwe cyane cyane muri Porutugali, Espanye na Afurika y'Amajyaruguru. Cork ni amikoro make, ariko nibyiza gukoresha, byoroshye kandi bikomeye, bifite kashe nziza, kandi bituma ogisijeni nkeya yinjira mumacupa, ifasha vino gukomeza gutera imbere mumacupa. Nyamara, divayi zimwe zifunze hamwe na corks zikunda kubyara trichloroanisole (TCA), bigatera kwanduza cork. Nubwo kwanduza cork bitangiza umubiri wumuntu, impumuro nziza nuburyohe bwa vino bizashira, bigasimbuzwa impumuro nziza yikarito itose, bizagira ingaruka kuburyohe.
Bamwe mu bakora divayi batangiye gukoresha imipira ya screw mu myaka ya za 1950. Igipapuro cya screw gikozwe muri aluminiyumu kandi gaze imbere ikozwe muri polyethylene cyangwa amabati. Ibikoresho bya liner byerekana niba vino ari anaerobic rwose cyangwa ikemerera ogisijeni kwinjira. Hatitawe ku bikoresho, ariko, divayi yafashwe irahagaze neza kuruta divayi ifunze kuko nta kibazo cyo kwanduza cork. Igifuniko cya screw gifite urwego rwo hejuru rwo gufunga kuruta cork, biroroshye rero kubyara reaction yo kugabanya, bikavamo impumuro yamagi yaboze. Ibi ni nako bimeze kuri vino ifunze cork.
2. Divayi ifunze divayi irahendutse kandi idafite ubuziranenge?
Imipira y'imigozi ikoreshwa cyane muri Ositaraliya no muri Nouvelle-Zélande, ariko ku rugero ruto muri Amerika no mu bihugu bya Kera ku Isi. 30% gusa bya divayi muri Reta zunzubumwe zamerika bifunze hamwe na capit ya screw, kandi nukuri ko zimwe muri divayi hano atari nziza cyane. Nyamara divayi zigera kuri 90% muri Nouvelle-Zélande zarafashwe, harimo divayi yo ku meza ihendutse, ariko na divayi nziza ya Nouvelle-Zélande. Kubwibyo, ntidushobora kuvuga ko divayi ifite imipira ya screw ihendutse kandi idafite ubuziranenge.
3. Divayi ntishobora gufungwa imipira ya screw ntishobora gusaza?
Gushidikanya gukomeye abantu bafite nukumenya niba divayi ifunze hamwe na capit ya screw ishobora gusaza. Hogue Cellars i Washington, muri Amerika, yakoze ubushakashatsi bwo kugereranya ingaruka ziterwa na cork naturel, corks artificiels hamwe na capit ya screw ku bwiza bwa divayi. Ibisubizo byerekanaga ko imipira ya screw yagumanye imbuto nziza nuburyohe bwa vino itukura numweru. Byombi bya cork artificiel na naturel birashobora gutera ibibazo hamwe na okiside hamwe no kwanduza cork. Nyuma y ibisubizo byubushakashatsi bimaze gusohoka, divayi zose zakozwe na Hogg Winery zahinduwe zifata imipira. Impamvu ifunga cork nibyiza mugusaza kwa divayi nuko yemerera ogisijeni runaka kwinjira mumacupa. Uyu munsi, hamwe niterambere ryikoranabuhanga, imipira irashobora kandi kugenzura ingano ya ogisijeni yinjira neza neza ukurikije ibikoresho bya gaze. Birashobora kugaragara ko imvugo ivuga ko divayi ifunze hamwe na kashe ya screw idashobora gusaza ntabwo ifite ishingiro.
Birumvikana ko kumva igihe cork ifunguye nikintu cyurukundo kandi cyiza. Ni ukubera kandi ko abaguzi bamwe bafite ibyiyumvo byo guhagarika igiti, inzoga nyinshi zitinyuka kudakoresha imipira ya screw nubwo baba bazi ibyiza byo gufata imipira. Ariko, niba umunsi umwe imipira ya screw itagifatwa nkikimenyetso cya divayi mbi, inzoga nyinshi zizakoresha imipira ya screw, kandi birashobora kuba ikintu cyurukundo kandi cyiza cyo gukuramo igikapu icyo gihe!
