Yogurt forms at a temperature range of 110°F to 115°F (43°C to 46°C). This warm environment is ideal for the active cultures, primarily Lactobacillus bulgaricus and Streptococcus thermophilus, to ferment the milk sugars into lactic acid. The fermentation process typically takes several hours, resulting in the thickening and tangy flavor characteristic of yogurt.
To make yogurt without using yogurt as an ingredient, you can use a starter culture containing live bacteria cultures, such as Lactobacillus bulgaricus and Streptococcus thermophilus. These cultures can be purchased in powdered form or from a previous batch of homemade yogurt. Heat milk to a specific temperature, add the starter culture, and allow it to ferment at a warm temperature for several hours until it thickens into yogurt.
Some of the best yogurt makers with temperature control available in the market include the Euro Cuisine YM80 Yogurt Maker and the Cuisinart CYM-100 Electronic Yogurt Maker. These machines allow you to control the temperature during the yogurt-making process, resulting in consistent and delicious yogurt.
The ideal milk temperature for making yogurt is around 110-115F (43-46C).

A few hours to a few weeks, depending on the temperature at which the yogurt is stored.
I would estimate a two hour limit for keeping yogurt at room temperature. Personally, I take it out of the refrigerator and eat it immediately. I see no need to keep it at room temperature.
The ideal temperature for fermenting yogurt milk is around 110-115F (43-46C) to achieve the best results.
Milk has a yogurt culture added to it, and is kept at the correct temperature for the bacteria of the culture to grow. The milk is converted to yogurt. You can then add any flavorings or additions you like.
you can freeze containers of yogurt, but it will take a lot of time. approximately three to eight hours to freeze because the yogurt reacts to the temperature in the freezer (or wherever you have put the yogurt to freeze). But the yogurt will still freeze because the temperature is more stronger. so it will take approximately three to eight hours depending on the flavour or/and ingredients.
The answer depends on whether or not the yogurt is at room temperature or refrigerated. Frozen is another entirely different category. Can you clarify?
Yes, you can make your own yogurt at home using milk and a yogurt starter culture. Simply heat the milk, add the culture, and allow it to ferment at a warm temperature for several hours. Once the yogurt has set, refrigerate it before consuming.
The yogurt was likely placed in boiling water to create a warm environment that promotes the growth of beneficial bacteria during the fermentation process. This temperature helps activate the live cultures in the yogurt, allowing them to multiply and thicken the mixture. Additionally, using boiling water ensures that the yogurt maintains a consistent temperature, which is crucial for achieving the desired texture and flavor.
