Fermentation Guides · Yogurt
For your first batch with Zoh’s Bulgarian yogurt starter, use one complete 5 g sachet with 500 ml dairy milk. Cool the prepared milk to 37–42°C before adding the culture, maintain that temperature while it sets, then refrigerate. No straining is required.
Before you start · First-batch steps · Troubleshooting
What you need
- One complete 5 g sachet of Zoh Bulgarian yogurt starter
- 500 ml dairy milk
- A clean food-safe jar with a cover and room for the milk
- A clean saucepan, stirring utensil and food thermometer
- A setup that maintains 37–42°C
The current pack contains two 5 g sachets. Use one for this first batch and keep the second sealed for a separate activation. The culture contains milk and is not vegan or dairy-free.
Make your first batch
- Prepare the milk. Start with commercially pasteurised dairy milk. Follow the milk-heating instructions supplied with the culture for your milk type. This page does not substitute a different starter’s heating procedure.
- Cool and add the starter. Measure the milk temperature. Once it is 37–42°C, stir in one complete 5 g sachet with clean utensils.
- Keep the temperature steady. Cover and maintain 37–42°C. Start checking after 6 hours. If it has not set, check at 2-hour intervals as directed on the current product page. Avoid repeatedly stirring or moving the container.
- Refrigerate once set. Chill the finished yogurt before eating or using it in recipes. You do not need to sieve or strain it.
Setting time varies with the milk, temperature and starter activity. The first check at 6 hours is not a promise that every batch will be ready then. If the batch is not setting as expected, contact Zoh rather than extending incubation indefinitely.
Making yogurt in an Indian kitchen
A warm Mumbai afternoon and a cool Gurgaon night can produce different conditions around the same jar. Measure the temperature; do not treat “overnight” as a reliable setting. A yogurt maker is optional, but stable warmth is essential. Check that your appliance can hold the specified range instead of assuming every yogurt setting is suitable.
Which milk should I choose?
Whole dairy milk is a straightforward starting point. Record the milk type and quantity so you can reproduce a result you like. Changing the milk can change the texture. For readers in Dubai, elsewhere in the GCC or Singapore, compare the actual milk label and processing instructions; a familiar brand name alone does not establish the same formulation.
How do I make the next batch?
The current product instructions allow reculturing from plain, successfully set yogurt. Set aside the starter portion with clean utensils before adding any fruit, sugar, salt or spices, then follow the reculturing instructions supplied with your pack. First activation with a dry sachet and reculturing with finished yogurt use different quantities; do not substitute one for the other.
Starter storage and finished-yogurt storage
Keep sealed sachets in a cool, dry place and follow the pack’s best-before date. The Bulgarian pack recommends keeping extra sachets in the freezer. Refrigerate finished yogurt. An instruction for storing a dry sachet does not apply to the milk after fermentation.
If your batch is not setting
Read the yogurt troubleshooting guide. Send the milk type, quantity, temperatures, incubation times and a clear photo to support@zohprobiotics.com. Do not turn a failed batch into lassi to hide the problem.
What can I make with the finished yogurt?
Use the chilled yogurt for pudina-jeera lassi, beetroot raita or a mint and coriander dip. Choose a dish in the yogurt recipe guide according to how thick your batch is.
Frequently asked questions
Do I need to strain Zoh Bulgarian yogurt?
No. Make it, let it set, refrigerate and eat. Hung dahi is an optional way to thicken already successful yogurt for a particular recipe.
Can I add fruit before setting?
For this first-batch method, make plain yogurt and add flavourings to individual portions after it has set and chilled. Keep any portion intended for reculturing plain.
Does a thick batch automatically have more protein?
No. The milk and final recipe determine the protein content. Texture alone is not a nutrition measurement.
Can I use a plant-based drink?
This guide covers dairy milk and a milk-containing starter. Use a culture and method specifically suited to your chosen plant-based drink for a dairy-free project.
