How long does it take to make yogurt?

Answer 1

When I made yogurt at home from milk (and half a spoon of old yogurt),

it took less than 24 hours, usually it set overnight. I think it depends on

the "starter" yogurt. When you start with store-bought yogurt, it's sometimes

hit and miss but once you have your lot going with no fake additives, it

sets overnight without a problem.

It will set within 3-5 hours if kept at a constant 43 Celsius or 110 Fahrenheit, and the milk is boiled and then cooled to 45C or 110F before you mix the seed yogurt, if you don't cool it before you mix you will kill the fermenting bacteria, if you don't boil then the milk molecules make it harder for the fermenting bacteria to ferment the milk. Also when you boil milk careful with the espresso foaming of the milk because it will spill and extinguish the flame of the gas, this will fill your room with explosive gas if left unattended.

Here is the routine:

Get the seed yogurt to warm up to room temp, 1 Cup.

Take 1 gallon of milk and boil it, then let it come back down in temperature to 110 F or 45 C.

Mix the seed and the milk for 20 seconds, and then seal the mixture in an air tight container.

Let the mix set for 3-5 hours at constant temp, if you don't have any means of constant temperature then it will take 5-8 hours, if left at low room temp then it might take 24 or it may never ferment.
