Paso 1: Preparación de la leche y cultivo láctico

Elige el tipo de leche
Choose the right type of milk for your yogurt-making needs. Whole, low-fat or nonfat milk can be used, depending on your desired level of creaminess.

Heat up the milk
Warm the milk to around 180°F (82°C) to pasteurize it and kill off any bacteria that may be present. You can use a thermometer to ensure the correct temperature.

Cool down the milk
Once the milk has reached the desired temperature, let it cool down to around 110°F (43°C). This is an important step, as most yogurt cultures won't grow well at high temperatures.

Add the starter culture
Add your yogurt starter culture or active dry yeast to the cooled-down milk. Mix well to ensure even distribution of the bacteria.

Create a warm environment
Transfer the mixture to a warm and draft-free place, such as an oven with the light on or a yogurt maker. The ideal temperature for fermentation is between 100°F (38°C) and 110°F (43°C).

Let it incubate
Allow the mixture to incubate for several hours, typically around 8-12 hours. During this time, the bacteria will start to ferment the lactose in the milk, producing lactic acid and thickening the mixture.

Check on progress
After a few hours, check on the mixture's progress by giving it a gentle stir. If you notice it has thickened slightly and developed a tangy smell, it's likely ready for the next step!

Remember to work quickly and carefully when preparing your milk and starter culture, as this will help prevent contamination and ensure successful fermentation.

Paso 2: Calentamiento y acidificación de la leche

Heat up the mixture
Gently heat the incubated mixture to around 180°F (82°C) to stimulate the bacterial activity and promote lactic acid production. This step helps to create a more acidic environment, which is essential for yogurt formation.

Maintain the temperature
Once you've reached the desired temperature, maintain it for about 30 minutes to allow the bacteria to adapt and start producing lactic acid. You can use a thermometer to monitor the temperature.

Cool down gradually
After heating, slowly cool the mixture down to around 120°F (49°C) to slow down the bacterial activity. This step helps to prevent over-acidification and promotes the growth of beneficial bacteria.

Check for acidity
Monitor the mixture's acidity by tasting it or using a pH meter. You're aiming for a slightly acidic taste, similar to plain yogurt. If it's too alkaline, you can adjust the temperature or add more starter culture.

Stabilize the mixture
Once the mixture has cooled down and reached the desired level of acidity, it's ready for the next step. Take your time and ensure the mixture is stable before proceeding to avoid any contamination or spoilage.

Remember to work carefully during this step, as sudden temperature changes can affect the bacterial activity and overall quality of your yogurt.

Paso 3: Fermentación y espesamiento de la leche

Fermentation begins
As the mixture cools down, the bacteria start to ferment the lactose in the milk, producing lactic acid and releasing carbon dioxide gas. This process can take several hours, depending on factors like temperature and bacterial activity.

Monitor the texture
Check the mixture's texture regularly, as it will begin to thicken and transform into a creamy yogurt-like consistency. You may need to stir the mixture gently to ensure even fermentation.

Taste and adjust
Sample the mixture occasionally to check its flavor and texture. If it's too thin or not sour enough, you can adjust the temperature or add more starter culture to promote further fermentation.

Watch for signs of spoilage
Keep an eye out for any signs of spoilage, such as an off smell, mold, or an unpleasant texture. If you notice anything unusual, it's best to discard the mixture and start again.

The final stretch
As the fermentation process nears completion, the mixture will have thickened significantly and developed a tangy, slightly sour taste. This is a sign that your yogurt is almost ready for the next step! Take your time and ensure the mixture has reached the desired consistency before proceeding.

Remember to be patient during this step, as the fermentation process can take several hours or even overnight. The wait will be worth it, though, when you enjoy your freshly made homemade yogurt!

Paso 4: Refrigerio y maduración del yogurt

Cool down and chill out
Once the fermentation process is complete, transfer the mixture to a refrigerator or a cold place to slow down the bacterial activity. This step helps to prevent over-maturation and preserve the yogurt' s texture.

Allow for maturation
Let the yogurt chill in the refrigerator for at least 4-6 hours or overnight to allow it to mature and develop its characteristic flavor and texture. You can also store it in an airtight container and keep it refrigerated for up to a week.

Check on the texture
After chilling, check the yogurt' s texture by gently stirring the mixture. If it has thickened to your liking, you can proceed to the next step. If not, you may need to adjust the temperature or add more starter culture to achieve the desired consistency.

Taste and adjust (again)
Before serving or storing the yogurt, taste it one last time to ensure it meets your expectations. If it' s too thin or needs a bit more tanginess, you can refrigerate it for another hour or two to allow it to mature further.

Enjoy your homemade yogurt!
Congratulations! You've successfully made homemade yogurt using the fermentation method. Now you can enjoy it as is, or use it as a base for other recipes like smoothies, parfaits, or as a topping for oatmeal or fruit.

Paso 5: Envasado y conservación del yogurt casero

Get creative with containers
Transfer the homemade yogurt to an airtight container, such as a glass jar or a plastic tub. You can also use Mason jars or silicone ice cube trays for a more rustic look.

Label and date it
Mark the container with the date you made the yogurt and any relevant storage instructions. This will help you keep track of how long it' s been stored and ensure food safety.

Store in the fridge
Keep the yogurt refrigerated at a temperature below 40°F (4°C) to slow down bacterial growth and prevent spoilage. You can store it for up to a week, depending on your personal preferences.

Freeze for later
If you don' t plan to consume the yogurt within a week, consider freezing it for future use. Frozen yogurt can be thawed and used in smoothies or as a topping for oatmeal or fruit.

Tips for freezing
When freezing, make sure to transfer the yogurt to an airtight container or freezer bag to prevent contamination. Label the container with the date and contents, and store it at 0°F (-18°C) or below. Frozen yogurt will typically last for several months.
