Uma kuziwa ekufakweni kwekhofi, abarosi abakhethekile kufanele bacabangele izici ezihlukahlukene, kusukela kumbala nokuma kuya ezintweni zokwakha kanye nezingxenye ezengeziwe.Nokho, isici esisodwa esinganakwa ngezinye izikhathi ubukhulu.
Usayizi wephakeji ungaba nomthelela obalulekile hhayi nje kuphela ekushayweni kwekhofi, kodwa nasezicini zalo ezithile ezifana nephunga elimnandi namanothi.Inani lesikhala elizungeze ikhofi uma lipakishwa, elibuye laziwe ngokuthi “i-headspace,” libalulekile kulokhu.
U-Hugh Kelly, Inhloko Yezokuqeqesha e-ONA Coffee ezinze e-Australia kanye nophumelele i-World Barista Championship ka-2017, ukhulume nami ngokubaluleka kosayizi bephakheji yekhofi.
Iyini i-headpace futhi ikuthinta kanjani ukusha?
Ngaphandle kwekhofi eligcwele i-vacuum, iningi lamaphakheji aguquguqukayo linendawo engenalutho egcwele umoya ngaphezu komkhiqizo owaziwa ngokuthi "i-headspace."
I-Headspace ibalulekile ekulondolozeni ukusha nokulondoloza izimfanelo zekhofi, kanye nokuvikela ikhofi ngokwenza umcamelo ozungeze ubhontshisi.“Abarosa kufanele bahlale bazi ukuthi singakanani isikhala esingaphezu kwekhofi ngaphakathi kwesikhwama,” kusho uHugh Kelly, i-Australia Barista Champion yase-Australia amahlandla amathathu.
Lokhu kungenxa yokukhululwa kwe-carbon dioxide (CO2).Uma ikhofi ligazingiwe, i-CO2 inqwabelana esakhiweni esinezimbotshana sikabhontshisi ngaphambi kokuba iphume kancane kancane ezinsukwini namaviki ambalwa alandelayo.Inani le-CO2 ekhofini lingaba nomthelela kuyo yonke into kusukela kuphunga elimnandi kuya kumanothi e-flavour.
Uma ikhofi lipakishwa, lidinga inani elithile legumbi ukuze i-CO2 ekhishwe ukuze izinze futhi idale umoya ocebile ngekhabhoni.Lokhu kusiza ukugcina ukucindezela phakathi kukabhontshisi nomoya ngaphakathi kwesikhwama kuzinzile, ukuvimbela ukusakazeka okwengeziwe.
Uma yonke i-CO2 ibingaphunyuka kungazelelwe esikhwameni, ikhofi belizowohloka ngokushesha futhi impilo yalo yeshalofu izoncipha kakhulu.
Nokho, kukhona indawo emnandi.U-Hugh uxoxa ngezinye zezinguquko ezingaba khona ezimpahleni zekhofi lapho i-headpace yesiqukathi sincane kakhulu: “Uma indawo yekhanda iminyene kakhulu futhi igesi ephuma ekhofini iminyene kakhulu kubhontshisi, ingaba nomthelela omubi izinga likabhontshisi. ikhofi,” uyachaza.
“Kungenza ikhofi linambitheke kakhulu futhi, ngezinye izikhathi, libe muncu kancane.”Nokho, okunye kwalokhu kungase kuncike kuphrofayela egazingiwe, njengoba ama-roast alula futhi asheshayo angasabela ngendlela ehlukile.”
Izinga lokukhipha umoya lingaphinde lithinteke isivinini sokugazinga.Ikhofi elosiwe ngokushesha livamise ukugcina i-CO2 eningi njengoba linesikhathi esincane sokuphuma kuyo yonke inqubo yokugazinga.
Kwenzekani njengoba i-headspace yanda?
Ngokwemvelo, indawo yekhanda emaphaketheni izokhula njengoba amakhasimende ephuza ikhofi lawo.Uma lokhu kwenzeka, igesi eyengeziwe evela kubhontshisi iyekwa ukuba isakazeke emoyeni ozungezile.
U-Hugh weluleka abantu ukuthi behlise i-headspace ngenkathi bephuza ikhofi labo ukuze balondoloze ubusha.
"Abathengi kufanele bacabangele indawo yekhanda," uyaphikisana."Kudingeka banciphise indawo ekhanda ukuze banqande ukusakazeka ngokuqhubekayo, ngaphandle uma ikhofi lisasha futhi lisadala i-CO2 eningi.Ukuze wenze lokhu, gcoba isikhwama bese usivikela usebenzisa i-tape.
Ngakolunye uhlangothi, uma ikhofi lilisha ngokukhethekile, kuhle ukugwema ukuminyanisa kakhulu isikhwama lapho abasebenzisi besivala ngoba igesi ethile isadinga indawo yokungena lapho ikhishwa kubhontshisi.
Ukwengeza, ukunciphisa i-headspace kusiza ukunciphisa inani le-oxygen esikhwameni.Umoya-mpilo ongena esikhwameni isikhathi ngasinye lapho sivulwa ungase ubangele ukuba ikhofi lilahlekelwe yiphunga lalo nobudala.Yehlisa amathuba okuba ne-oxidation ngokucindezela isikhwama futhi yehlise inani lomoya ozungeze ikhofi.
Ukukhetha usayizi wephakheji ofanele wekhofi lakho
Kubalulekile kuma-roasters akhethekile ukwenza isiqiniseko sokuthi i-headspace yokupakishwa kwawo kokubili kuncane ngokwanele ukugcina ubusha futhi bukhulu ngokwanele ukuvimbela ukushintsha izici zekhofi.
Nakuba zingekho iziqondiso eziqinile futhi ezisheshayo zenani le-headspace ikhofi okufanele libe nayo, ngokusho kukaHugh, i-roaster inesibopho sokwenza ukuhlola ukuze inqume ukuthi yini esebenzayo kumkhiqizo wabo ngamunye.
Okuwukuphela kwendlela yama-roasters yokunquma ukuthi inani le-headspace lilungele ikhofi labo ukwenza ukunambitha eceleni, ngokusho kwakhe.Yonke i-roaster ilwela ukukhiqiza ikhofi elinephrofayili ye-flavour eyingqayizivele, isizinda, nokuqina.
Sengiphetha, isisindo sikabhontshisi abanjwe ngaphakathi sinquma ubukhulu bokupakisha.Ukupakisha okukhudlwana, okufana nezikhwama eziphansi eziyisicaba noma ezisemaceleni, kungase kudingeke emananini amakhulu kabhontshisi kubathengi bezitolo ezinkulu.
Ubhontshisi wekhofi odayiswayo ngokuvamile unesisindo esingu-250g kubasebenzisi basekhaya, ngakho-ke izikhwama zokuma noma ze-quad-seal zingaba ezifaneleka kakhudlwana.
U-Hugh weluleka ngokuthi ukwengeza i-headspace eyengeziwe “kungase kube [kuzuzise] ngoba [kuzo]…kukhanyise [ikhofi] uma unekhofi elisindayo [elinephrofayela eyosiwe] emnyama.”
Ama-headspace amakhudlwana, nokho, angase abe yingozi uma upakisha ukukhanya noma ama-roast aphakathi nendawo, njengoba uHugh esho, “Kungase kubangele [ikhofi] ukuba liguge…ngokushesha.”
Ama-valve okukhipha amanzi kufanele engezwe nasezikhwameni zekhofi.Ama-vent-way-way abizwa ngokuthi ama-degassing valves angangezwa kunoma yiluphi uhlobo lokupakisha ngesikhathi noma ngemva kokukhiqiza.Zivimbela umoya-mpilo ukuthi ungangeni esikhwameni kuyilapho zivumela i-CO2 enqwabelene ukuthi ibaleke.
Naphezu kokuba into evame ukushaywa indiva, usayizi wephakheji ubalulekile ekugcineni ubusha kanye nezimfanelo ezihlukile zekhofi.Ikhofi lizoshintsha libe lidala uma kunesikhala esikhulu noma esincane kakhulu phakathi kukabhontshisi nokupakishwa kwawo, okungase futhi kubangele ukunambitheka “okusindayo”.
Kwa-Cyan Pak, siyabona ukuthi kubaluleke kangakanani ukuthi abaroga abakhethekile banikeze amakhasimende abo ikhofi lekhwalithi ephezulu kakhulu.Singakusiza ukuthi wakhe amaphakheji anosayizi ofanele wekhofi lakho, noma ngabe ubhontshisi ophelele noma umhlabathi, ngosizo lwezinsizakalo zethu zedizayini ezinekhono kanye nezinye izindlela ongazikhetha ngokuphelele.Siphinde futhi sinikeze ama-valve okukhipha amanzi angenawo i-BPA, agaywa kabusha angena kahle ngaphakathi kwezikhwama.
Xhumana nathi ukuze ufunde kabanzi mayelana nephakheji yethu yekhofi evumelana nemvelo.
