The cultured milk is then transferred to preheated jars, sealed, and placed in the incubation chamber to ferment undisturbed. Yogurt incubated at 115°F/46°C will coagulate within about 3 hours, but may easily bunch up if incubated too long.
What happens if you overcook yogurt?

How long can you leave yogurt in Maker?
Fact: If the temperature of thermophilic yogurt drops below 90°F, other unknown bacteria will grow and change the skin, texture, and safety of the yogurt. Fact: This is not a problem if the cooker is intentionally set for up to 24 hours.
Does cooking yogurt longer make it thicker?
Heating milk denatures the proteins and allows them to form stronger networks when exposed to acids (such as lactic acid produced by bacteria in yogurt cultures). Thus, higher temperatures held for a longer time will give you firmer yogurt.

Why is my yogurt not thickening?
Too hot or too cool will negatively affect the bacteria in yogurt starter cultures. You really need a yogurt maker. A potential cause of yogurt is bacterial fermentation slowing down, going dormant, or being killed by an uneven heat source. In any case, a constantly long fermentation always results in a constantly thick yogurt.
Can you ferment yogurt for 24 hours?
A 24-hour yogurt is a yogurt that has fermented for 24 hours, much longer than the usual 4 to 7 hours. The additional fermentation time leads to the lactose disintegrating into a more absorbable form, thus not fermenting in the gut and feeding bacterial overgrowth.
What happens if you use too much yogurt starter?
Do not use more starter than recommended. Using too much starter allows bacteria to run out of food before the yogurt has fully fermented the milk. The result is often thinner, sometimes bitter yogurt.
What is the best temperature for making yogurt?

How long do you boil milk to make yogurt?

Why is my homemade yogurt grainy?
When the yogurt base is pumped into the fermentation VAT, it immediately coagulates (or directly acidifies), resulting in a very stable milk protein. This card may not re-dissolve into the base during incubation and may not be broken down by the smooth device, resulting in a coarse product.
Can you get food poisoning from homemade yogurt?
If proper food handling and safety methods are followed, yogurt can be made safely without fear of foodborne illness taking over the product. Converting milk to yogurt is an excellent way to extend the shelf life of milk by one to two weeks and is a safe dairy choice for those who are lactose intolerant.

Is it necessary to boil milk when making yogurt?
Yogurt can be made with room temperature milk, but for the most consistent results, most experts recommend heating the milk to at least 180°F or boiling point first. Heating milk produces a richer end product and kills any bad bacteria in the milk.
Why is my yogurt gluey?
Introducing bacteria when milk is too hot results in sour curd with a lot of whey (dahi ka paani). When milk is not heated enough, it becomes lacy/gooey/string dahi. If low-fat or skim milk is used, the dahi may not be firm enough.
