Milk kefir fermentation is a natural fermentation process in which milk kefir grains — a symbiotic culture of beneficial bacteria and yeasts — convert milk sugars (lactose) into lactic acid, creating a tangy, creamy, probiotic-rich drink. During fermentation, the yeasts also produce small amounts of natural carbonation, contributing to milk kefir’s characteristic texture and flavor.

U samo 3 koraka uživajte u najboljem domaćem kefiru s domaćim sastojcima.
1. Dodajte zrnca i mlijeko
2. Ostavite kako bi fermentirali
3. Uživajte u kefiru
Što čini Kefirko teglice za fermentaciju tako posebnima?
Inovativne komponente koje omogućuju optimalne uvjete za fermentaciju.
STAKLENA POSUDA
Staklene posude širokog grla su jednostavne za upotrebu i čišćenje. Staklo je materijal koji ne reagira s fermentiranim pićima, čuva njihov okus i sprječava kontaminaciju. Prozirno staklo omogućava učinkovito praćenje procesa fermentacije.
ZRAČNI POKLOPAC
Može se ostaviti djelomično otvorenim za protok zraka tijekom fermentacije. Sprječava ulazak nečistoća (prašine, kukaca) u posudu, čak i kada je malo otvoren.
CJEDILO
Cjedilo ugrađeno u poklopcu ima otvore koji su na jednoj strani širi, a na drugoj uži za lakše cijeđenje gušćeg ili rjeđeg kefira.
STRUGALO
Za miješanje kefirnih zrnaca tijekom cijeđenja i odvajanje od kefira. Tijekom cijeđenja povoljno pokriva otvor u sredini poklopca, što olakšava postupak cijeđenja.
PLANIRAJ KOLIČINE
Oznake na staklenci dijele volumen na količine od 300 ml.
CJEDILO ZA AGRUME
Jednostavno ga pričvrstite na cjedilo i dodajte svježi sok citrusa u vaš vodeni kefir.
Zašto domaći kefir, a ne kupovni?
Domaće je uvijek bolje.
Optimalni uvjeti za fermentaciju
Više dobrih bakterija koje imaju blagotvorni učinak na naše tijelo i zdravlje
Kefir ima brojne pozitivne učinke na zdravlje. Možete ga uživati samostalno ili miješati u različita jela i konzumirati kao obrok
Detoksikacija organizma
Poboljšana probava
Olakšano unošenje kalcija
Povećanje imunih sposobnosti organizma
Antimikrobni učinci i prevencija infekcija
Antioksidativna svojstva (usporavanje procesa starenja i skleroze, snižavanje kolesterola)
Više od 30.000 ih je već prodano.
Ljudi ga jednostavno obožavaju.
Kako bi napravili najbolji kefir na svijetu, ne morate nam vjerovati.

“Obožavam domaći kefir zbog dobrih bakterija koje koriste mom zdravlju i posebno zdravlju moje probave. Kefiro posuda za fermentaciju je jednostavna za upotrebu i pripremu mliječnog ili vodenog kefira, jer zamjenjuje nekoliko posuda i cjediljku.”
