Instructions for Homemade Yogurt (Step-by-Step)

Equipment:

  • 1/2 gallon of milk (preferably NOT ultra pasteurized)
    Note: Any type of milk can be used…raw, unhomogenized, homogenized, 2%, skim, whole milk, goat, sheep, and yes, even ultra pasteurized if necessary)
  • Yogurt Culture (a “sweet yogurt culture” is a good choice for beginners)
    Note: You can also use 1 Tbs. plain store-bought yogurt as the culture
  • Stainless steel or glass pot (these are the best materials to use when making yogurt because they are easily cleaned and sterilized
  • Thermometer

 

Directions
  1. Pour 1/2 Gallon of milk into a stainless-steel pot and heat to 185ºF on a stove top over medium heat.
  2. Once heated let milk sit for 30 minutes. This will enhance the creamy texture of the yogurt.
  3. Skim the ‘skin’ from the surface of the milk

 

 

3.  Quickly cool milk to 115ºF, by placing the pot into a sink filled with cold water.
4. Once cooled, set pot on the countertop, add Yogurt Culture to the milk and mix well.
     Note: A Yogurt culture is a ‘friendly bacterium’ that converts lactose, milk sugar, into lactic acid. This process adds flavor and thickens milk it into a yogurt.
5.  Keep the milk between 110ºF and 115ºF for 6-12 hours until a thick yogurt forms (longer time = thicker yogurt).

Ways to Keep Milk Warm:
 – Place a lid on the pot and cover with a towel
– Set pot of milk into an insulated cooler
– Transfer milk into a Yogurt Maker
 – Pour milk into a clean slow cooker on a low heat setting

6. Once set, yogurt can be stored in a covered container in the refrigerator for 7-14 days.

 

Greek Yogurt

Greek Yogurt is simply a thicker form of regular yogurt.
Before storing in the refrigerator, ladle yogurt (trying not to break up the curds) into a large colander lined with Butter Muslin to drain for 1-2+ hours. This can be done at room temperature or in the refrigerator.  You can customize the texture of your Greek Yogurt by draining for more or less time.

 

12 FAQs about Yogurt Temperature
1. Can I make yogurt at room temperature?
     No, room temperature is typically not warm enough to activate the bacterial fermentation process required to make yogurt.
2. Can I make yogurt at a higher temperatures?
     Using a temperature higher than 115°F (46°C) can kill the bacteria, preventing proper fermentation, so it is not recommended.
3. What happens if the temperature is too low?
     At temperatures below 110°F (43°C), the beneficial bacteria may not activate, resulting in runny or inconsistent yogurt.
4. Can I make yogurt without a thermometer?
     While using a thermometer is the most accurate method, you can still make yogurt without one by following the general range
guidelines and carefully monitoring
the consistency and taste.
5. Can I use a slow cooker to make yogurt?
     Yes, a slow cooker can be utilized if it has a “keep warm” setting that maintains the recommended temperature range.
6. Can I make yogurt without a yogurt maker?
     Yes, there are various methods to make yogurt without a yogurt maker, such as using a thermos, Instant Pot, or even a heating pad with proper insulation.
7. Can I incubate yogurt in direct sunlight?
     Direct sunlight does not provide a controlled temperature range and should be avoided as it may lead to inconsistent results.
8. Can I heat the milk too much before adding the yogurt culture?
     Yes, if the milk is heated above 120°F (48°C), it may kill the live bacteria in the yogurt culture, inhibiting fermentation.
9. Can I add the yogurt culture while the milk is hot?
     It is best to allow the milk to cool down to around 110°F (43°C) before adding the yogurt culture to ensure the viability of the bacteria.
10. Can I use a microwave to heat the milk?
       While possible, using a microwave to heat the milk can be challenging as it heats unevenly and may result in hot spots or overheating.
11. Can I cool the yogurt mixture quickly in the refrigerator?
      Rapid cooling in the refrigerator can disrupt the fermentation process, so it is recommended to cool the yogurt mixture gradually at room temperature.
12. Can I freeze or freeze-dry homemade yogurt?
      Yes, you can freeze homemade yogurt, but the texture may become grainy, and the live cultures may become less effective.
