Txij li ntau tshaj kaum xyoo dhau los, qee qhov ntawm Burgundy cov cawv dawb dawb tau ntsib oxidation ntxov ntxov, uas ua rau cov neeg sau cawv xav tsis thoob.10 xyoo dhau los, nws tau pib qhia qhov kev poob qis.Qhov tshwm sim ntawm qhov tshwm sim oxidation ntxov ntxov no feem ntau nrog cov cawv txiv hmab ua huab, ntau dhau oxidation tsis hnov tsw hauv lub raj mis, yuav luag ua rau cov caws pliav tsis tuaj yeem, thiab qhov kev txhawj xeeb tshaj plaws yog qhov tshwm sim no tsis tuaj yeem xav txog.Nyob rau hauv tib lub thawv ntawm caw, ib lub raj mis cawv tej zaum yuav muaj oxidation ntxov ntxov.Xyoo 1995, qhov tshwm sim oxidation no tau pom thawj zaug los ntawm tib neeg, thiab nws tau pib muaj kev txhawj xeeb hauv xyoo 2004, uas ua rau muaj kev sib tham sib tham thiab txuas ntxiv mus rau hnub no.
Yuav ua li cas Burgundian winemakers cuam tshuam nrog no oxidation unpredictable?Yuav ua li cas oxidation ntxov ntxov cuam tshuam rau Burgundy wines?Ntawm no yog ib daim ntawv teev cov neeg cog qoob loo teb li cas.
Ua ntej, pib nrog wine cork
Nrog rau kev nce ntawm cov cawv txiv hmab, ntau thiab ntau cov tub lag luam cawv thoob plaws ntiaj teb tau siv cov ntoo qhib ntoo hauv ntau qhov kev ua kom zoo, uas ib zaug ua rau cov khoom lag luam ntoo qhib ntau tshaj qhov xav tau.Txhawm rau ua kom tau raws li qhov xav tau, cork manufacturers tshem tawm cov tawv ntoo uas siv los ua cork los ntawm cov ntoo qhib lub cev ntxov ntxov.Txawm hais tias lub cork yog mature, qhov zoo ntawm cork uas tsim los tseem txo qis, uas ua rau oxidation ntxov ntxov.lus nug.Kuj tseem muaj qhov xwm txheej uas oxidation ntxov ntxov vim muaj teeb meem cork ua rau muaj teeb meem me me ntawm Domaine des Comtes Lafon thiab Domaine Leflaive, cov laj thawj tshwj xeeb uas tsis paub.
Txhawm rau tiv thaiv oxidation ntxov ntxov, qee cov tub lag luam cawv hauv Burgundy tau qhia DIAM corks txij li xyoo 2009. DIAM corks raug kho nrog kub thiab siab siab ntawm cov ntoo qhib cov khoom siv los ua DIAM corks.Ntawm qhov tod tes, TCA residues nyob rau hauv cov cawv txiv hmab corks raug tshem tawm.Ntawm qhov tod tes, cov pa oxygen permeability yog tswj nruj heev, yog li ntawd qhov tshwm sim ntawm oxidation ntxov ntxov yog txo qis.Tsis tas li ntawd, qhov teeb meem ntawm oxidation ntxov ntxov tuaj yeem ua rau qeeb qeeb los ntawm kev nce qhov ntev thiab txoj kab uas hla ntawm cov cawv txiv hmab cork.
Qhov thib ob, txo qhov cuam tshuam ntawm pwm
Thaum lub sij hawm loj hlob ntawm pwm, ib hom laccase (Laccase) yuav raug tsim, uas muaj peev xwm ua kom muaj zog oxidation ntawm cawu cub.Yuav kom txo tau qhov muaj laccase, winegrowers nyob rau hauv Burgundy txheeb cov txiv hmab txiv ntoo mus rau qhov loj tshaj plaws, thiab tshem tawm tej yam puas thiab tej zaum pwm-contaminated grape particles, thiaj li yuav inhibit qhov ua tau ntawm oxidation ntxov ntxov yav tom ntej.
Thib peb, sau thaum ntxov
Kev sau qoob loo lig, uas pib thaum xyoo 1990, tau ua rau cov cawv txiv hmab uas muaj qhov sib npaug, puv, thiab ntau dua, tab sis nrog kev poob acidity.Ntau lub wineries ntseeg hais tias siab acidity yuav txo tau qhov tshwm sim ntawm oxidation ntxov ntxov.Kev sau qoob loo thaum ntxov hauv Meursault tsis tshua muaj kev txom nyem los ntawm oxidation ntxov ntxov.Nyob rau hauv txhua rooj plaub, muaj ntau thiab ntau wineeries nyob rau hauv Burgundy sau ua ntej, thiab cov wines uas ua tau ntau ilv thiab sib npaug, es tsis yog tag nrho thiab tuab li lawv yav dhau los.
Plaub, muaj zog juicing
Lub airbag xovxwm yog thawj qhov kev xaiv ntawm niaj hnub winemakers.Nws maj mam nyem thiab zom cov tawv nqaij, tshem tawm cov pa oxygen, ua kua txiv hmab txiv ntoo sai dua, thiab ua rau cov cawv txiv hmab uas muaj zog dua.Txawm li cas los xij, cov kua txiv hmab txiv ntoo squeezed tawm nyob rau hauv qhov ua tiav oxygen cais tawm Tab sis exacerbated qhov tshwm sim ntawm oxidation ntxov ntxov.Tam sim no qee qhov chaw ua lag luam hauv Burgundy tau xaiv rov qab mus rau lub thav duab xovxwm lossis lwm yam xovxwm uas muaj zog extrusion quab yuam, ua raws li kev lig kev cai thiab zam qhov tshwm sim ntawm oxidation ntxov ntxov.
Thib tsib, txo kev siv cov sulfur dioxide
Nyob rau sab nraum qab ntawm txhua lub raj mis cawv, muaj cov ntawv qhia kom ntxiv me me ntawm sulfur dioxide.Sulfur dioxide ua raws li antioxidant hauv cov txheej txheem winemaking.Txhawm rau ua kom cov kua txiv hmab txiv ntoo tshiab thiab tiv thaiv cov kua txiv hmab txiv ntoo los ntawm oxidation, ntau thiab ntau sulfur dioxide yog siv.Tam sim no vim muaj qhov tshwm sim ntawm oxidation ntxov ntxov, ntau lub wineries yuav tsum xav txog tus nqi ntawm sulfur dioxide siv.
Thib rau, txo kev siv cov ntoo qhib tshiab
Puas muaj feem ntau ntawm cov ntoo qhib tshiab tuaj yeem siv los ua cov cawv txiv hmab zoo?Qhov feem ntau ntawm cov ntoo qhib tshiab, lossis txawm tias cov ntoo qhib tshiab tag nrho los cog cov cawv txiv hmab, tau dhau los ua neeg nyiam heev txij li thaum xaus ntawm lub xyoo pua 20th.Txawm hais tias cov ntoo qhib tshiab ua rau muaj qhov nyuaj ntawm cov cawv txiv hmab rau qee qhov, ntau dhau ntawm qhov no hu ua "chiv tsw" ua rau cov cawv poob nws cov yam ntxwv qub.Cov ntoo qhib ntoo tshiab muaj cov pa oxygen permeability siab, uas tuaj yeem ua kom nrawm nrawm ntawm oxidation ntawm cawv.Txo kev siv cov ntoo qhib tshiab kuj yog ib txoj hauv kev los txo cov oxidation ntxov ntxov.
Xya, txo qhov sib tov thoob (Batonnage)
Lub thoob nplawm yog ib txheej txheem hauv cov txheej txheem cawv.Los ntawm nplawm cov poov xab nyob rau hauv cov ntoo qhib thoob, cov poov xab tuaj yeem ua kom cov hydrolysis thiab sib txuas ntxiv oxygen, thiaj li ua tiav lub hom phiaj ntawm kev ua kom cov cawv txiv hmab puv thiab ntau mellow.Xyoo 1990, cov txheej txheem no kuj nrov heev.Yuav kom ua tiav ib puag ncig saj, cov thoob tau nplawm ntau thiab ntau zaus, kom cov pa ntau dhau tau muab tso rau hauv cawv.Qhov teeb meem ntawm oxidation ntxov ntxov ua rau lub winery yuav tsum xav txog cov sij hawm uas siv cov thoob.Txo tus naj npawb ntawm cov thoob yuav ua rau cov cawv dawb brewed tsis dhau rog tab sis kuj muag heev, thiab nws tuaj yeem tswj tau qhov tshwm sim ntawm oxidation ntxov ntxov.
Tom qab kev txhim kho ntawm ntau cov txheej txheem saum toj no, qhov tshwm sim ntawm oxidation ntxov ntxov tau poob qis, thiab tib lub sijhawm, kev siv ntau dhau ntawm cov thoob tshiab nrov nyob rau thaum xaus ntawm lub xyoo pua xeem thiab "rog" style ntawm brewing tau txwv. mus rau ib qho twg.Niaj hnub no Burgundy wines yog qhov muag heev thiab ntuj, thiab lub luag haujlwm ntawm "neeg" tau dhau los ua me.Qhov no yog vim li cas Burgundians feem ntau hais txog kev hwm ntawm xwm thiab terroir.
