Pakati peYunyunzvinwiwa zvakaitwa nemaoko, kunakirwa kwekapu yekofizvinonyanya kuenderana neunyanzvi hwebibi.Kune zvakawanda zvakasiyana-siyana zvinokanganisa kunaka kwekofi, uye sevatengi, tinogona kungosarudza nguva yakareba sei kofi inotonhora uye nguva yakareba sei tisati tanwa.Kana iwe ukagadzira yako kofi kumba, kunyangwe uine ese ekofi bhinzi uye maturusi muruoko rwako, zvinoita sekunge haugone kuenderana nemhando yechitoro chekofi.Pashure pezvose, munhu angagadzira sei kapu yekofi inofananidzwa nechitoro chekofi?
Kudzidzira kwakawanda harisi dambudziko, asi munyori-mubatanidzwa webhuku "Mvura yeKofi: Sainzi Nyaya Manual" uye anoshamwaridzana purofesa wezve computational zvinhu uye chemistry paYunivhesiti yeOregon, Christopher Hendon, anotenda kuti vanogadzirira vanofanirawo kugona misimboti yechemistry uye fizikisi panguva imwe chete.Zvinosiyana-siyana senge tembiricha yemvura, kunaka kwemvura, kugovera chidimbu, chiyero chemvura kusvika paupfu, uye nguva inoshandiswa zvinokanganisa kuravira kwekupedzisira kwekombe.Kuti uite kofi yakanaka, unofanirwa kudzidza kudzora izvi zvakasiyana.
Kazhinji, kuwanda kwezvinhu (organic acids, inorganic acids, heterocyclic compounds, Mena reaction products, etc.) yekofi yatakajaira.kunwayakakamurwa kuva marudzi maviri: imwe ndeye 1.2 - 1.5%, yakadai sekofi yekudonha, uye imwe yacho yakakwirira se8 - 10%., Zvakadai se espresso.Kofi yeTurkey yakadai sekubaya-maoko, muchina weFrench, siphoning, kudonha kwemuchina, kana kofi yeTurkey yakanyatsopiswa nekofi poda yemvura yemugero inogona kusvika kune density ye1.2 - 1.5%;nepo kofi yakasimba se8 - 10% inoshandisa muchina wekofi.Kuwanda kwezvigadzirwa zvekofi kunonyanya kuparadzaniswa kubva pamavambo ayo, asi zvinotevera zvakakosha.
1. Tembiricha uye kumhanya
Zvinogona kuonekwa kubva pamusoro apa kuti nzira dzakaderera dzekubika kofi dzakakamurwa kuita mapoka maviri: kunyura uye kudonha.Kubva pakuona kwemuviri, musiyano mukuru ndewekuti bhinzi dzekofi dzine tembiricha yepamusoro pane kudonha kana dzanyorova.Kutaura zvazviri, nguva yakawanda-inopedza nguva yekubvisa kofi haisi yekunyungudutsa caffeine pamusoro pezvimedu, asi kumirira kuti kunhuhwirira kwekofi kupfuure nepakati pezvimedu zvose uye kusvika pakusangana pakati pemvura nekofi.Urefu hwenguva inoshandiswa inosiyana zvichienderana nekupisa kwemvura.Iyo yakakwirira yekupisa kwezvimedu zvebhinzi yekofi, iyo yakawanda inonaka yemakemikari mairi inogona kutorwa.Nekudaro, kana tembiricha yakakwira zvakanyanya, inonyungudutsa mamwe makomisheni asingadiwi mumvura uye kukanganisa kuravira.
Ukuwo, kugezesa maoko uye dzimwe nzira dzekudonha mvura dzinotora nguva kuti mvura iyerere nemubhinzi dzekofi.Nguva yekubika inoenderana nekupisa kwemvura uye kuwanda kwebhinzi yekofi, saka kuverenga kwakanyanya kuoma.
2. Chiyero chebhinzi yekofi kumvura
Paunenge uchishandisa nzira yekudonhedza, yakanyanyisa bhinzi yekofi zvimedu zvichawedzera nguva yekugadzirira uye vhoriyamu yekubvisa.Mubiki anogona kuwedzera chiyero chemvura kune bhinzi yekofi nekuderedza kuwanda kwebhinzi yekofi, asi panguva imwechete inoderedzawo nguva yekubika maererano.Naizvozvo, kudonha kunonetsa kupfuura kunyura, uye unogona kugadzira kapu yakanaka yekofi nekuziva zvese.
3. Unhu hwemvura
Kunyange kana mitemo miviri iri pamusoro ichiitwa zvakanaka, zvakaoma kuvimbisa kuti kofi yakabikwa yakarurama.Hendon akataura kuti pane zvimwe zviviri zvingakanganisa kunaka kwekofi, imwe yacho ipH yemvura.
Kofi chinwiwa chine acidic, saka pH yemvura yekubikisa yakakoshawo.Kofi yakabikwa nemvura yakaderera HCO₃⁻ (Bicarbonate) (inozivikanwawo semvura yakapfava) ine acidity yepamusoro;kana kofi yakabikwa nemvura ine yakakwira HCO₃⁻ zvirimo (kureva mvura yakaoma), inoderedza iyo yakasimba uye yakakurumbira acidity.Zvakanakisa, zviri nani kushandisa mvura ine kemikari yakakodzera yekubika kofi.Nekudaro, zvakaoma kuziva kusungirirwa kweHCO₃⁻ mumvura yepombi.Hendon anokurudzira kuti uedze Evian mineral water neimwe yeakanakisa HCO₃⁻ content (kusvika 360 mg per litre) yekubika kofi., Enzanisa migumisiro yezviviri.
4. Kugoverwa kwechikamu
Chero mudiwa mukuru wekofi achakuudza kuti blade grinders haisi iyo yakanakisa grinder maturusi, nekuti bhinzi dzekofi dzavanogaya ndedzoukobvu hwakasiyana, izvo zvisina kunaka kudhirowa.Zvakanakisisa kushandisa burr grinder, iyo inoshandisa magiya maviri akafanana kukuya bhinzi yekofi zvishoma nezvishoma, uye mhedzisiro yacho inowedzera.
Pagara paine gakava pamusoro pekukora kwakakodzera.Zvinonzi iyo yakanakisa bhinzi yekofi yakagadzika, zviri nani, inowedzera pamusoro pezvimedu, uye inofambisa kubviswa kweiyo yakanakisisa uye yakasimba yekofi inonaka;Zvinonzi zvakare kuti coarser zviri nani, kudzivirira yakawandisa kutorwa kusunungura astringency.Hendon anotenda kuti ukobvu hunoenderana nekuravira kwake.
