Ọtụtụ ndị mmadụ na-eche na mmanya e ji okpu screw kpuchiri dị ọnụ ala, ọ pụghịkwa ịka nká. Okwu a ọ̀ ziri ezi?
1. Cork VS. Mkpọsa okpu
A na-eme ihe mkpuchi ahụ site na ogbugbo nke osisi oak. Osisi Cork bụ ụdị osisi oak nke a na-akụkarị na Portugal, Spain na North Africa. Cork bụ obere ihe onwunwe, ma ọ na-arụ ọrụ nke ọma iji mee ihe, na-agbanwe ma dị ike, nwere akara dị mma, ma na-ekwe ka obere ikuku oxygen banye na karama ahụ, na-enyere mmanya aka ịnọgide na-etolite na karama ahụ. Agbanyeghị, ụfọdụ mmanya ejiri corks mechie na-adịkarị mfe imepụta trichloroanisole (TCA), na-ebute mmetọ cork. Ọ bụ ezie na mmetọ cork adịghị emerụ ahụ mmadụ, ísì na ụtọ nke mmanya ahụ ga-apụ n'anya, dochie anya ísì musty nke katọn mmiri mmiri, nke ga-emetụta uto.
Ụfọdụ ndị na-emepụta mmanya malitere iji screw okpu na 1950s. The ịghasa okpu ka nke aluminum alloy na gasket n'ime bụ nke polyethylene ma ọ bụ tin. Ihe nke liner na-ekpebi ma mmanya ahụ bụ kpamkpam anaerobic ma ọ bụ ka na-enye ohere ụfọdụ oxygen ịbanye. Otú ọ dị, n'agbanyeghị ihe onwunwe ahụ, mmanya a kpụkọrọ akpụkọ na-esikwu ike karịa mmanya a gbara agba n'ihi na ọ dịghị nsogbu mmetọ cork. Okpu mkpuchi ahụ nwere akara dị elu karịa nke mkpuchi, n'ihi ya, ọ dị mfe ịmepụta mmeghachi omume mbelata, na-ebute isi nke àkwá rere ure. Nke a bụkwa ihe gbasara mmanya ndị ejiri cork mechie.
2. Mmanya ndị a kpụkọrọ akpụkọ hà dị ọnụ ala na ndị na-adịghị mma?
A na-eji okpu skru eme ihe na Australia na New Zealand, mana ruo n'ókè dị nta na United States na mba ụwa ochie. Naanị 30% nke mmanya na United States ka ejiri mkpuchi mkpuchi mechie, ma ọ bụ eziokwu na ụfọdụ mmanya ebe a adịghị mma. Ma ihe dị ka 90% nke mmanya New Zealand bụ ihe mkpuchi, gụnyere mmanya tebụl dị ọnụ ala, kamakwa ụfọdụ mmanya kacha mma nke New Zealand. Ya mere, a pụghị ikwu na mmanya ndị nwere mkpuchi mkpuchi dị ọnụ ala na nke adịghị mma.
3. Enwere ike ịka nká na mmanya ejiri mkpuchi mkpuchi mechie?
Ihe kacha enwe obi abụọ ndị mmadụ nwere bụ ma mmanya ejiri okpu screw kpuchiri ọ ga-aka nká. Hogue Cellars na Washington, USA, mere nnwale iji tụnyere mmetụta nke corks eke, corks artificial na screw cap na àgwà mmanya. Nsonaazụ gosiri na mkpuchi mkpuchi na-echekwa ísì ụtọ na ụtọ nke mmanya na-acha ọbara ọbara na nke ọcha. Ma okwuchi arụrụ arụ na nke eke nwere ike ịkpata nsogbu na oxidation na mmetọ cork. Mgbe nsonaazụ nke nnwale ahụ pụtachara, mmanya niile nke Hogg Winery rụpụtara ka agbanwere ka ọ bụrụ mkpuchi ịghasa. Ihe kpatara mmechi mkpuchi ahụ dị mma maka ịka nká mmanya bụ na ọ na-enye ohere ka ikuku oxygen banye karama ahụ. Taa, site na ọganihu nke nkà na ụzụ, mkpuchi mkpuchi nwekwara ike ịchịkwa ọnụọgụ oxygen na-abanye n'ụzọ ziri ezi dịka ihe nke gasket si dị. Enwere ike ịhụ na nkwupụta na mmanya ejiri mkpuchi screw kpuchiri enweghị ike ịka nká adịghị mma.
N'ezie, ige ntị n'oge a na-emeghe ihe mkpuchi ahụ bụ ihe na-adọrọ mmasị na nke mara mma. Ọ bụkwa n'ihi na ụfọdụ ndị na-azụ ahịa nwere mmetụta nke nkwụsị osisi oak, ọtụtụ ndị na-eri nri anaghị anwa anwa iji screw caps ngwa ngwa ọbụlagodi na ha maara uru nke mkpuchi mkpuchi. Otú ọ dị, ọ bụrụ na otu ụbọchị, ọ bụrụ na a naghị ewere mkpuchi mkpuchi mmanya dị ka ihe nnọchianya nke mmanya na-adịghị mma, ọtụtụ wineries ga-eji okpu screw, ọ pụkwara ịghọ ihe ịhụnanya na ihe mara mma iji wepụ okpu ahụ n'oge ahụ!
