Fermentation Guides · Yogurt
Start with a plain dairy milk supported by your starter’s instructions, then keep that milk consistent while you learn the process. Milk choice changes the result, but a fuller-fat label cannot compensate for an unsuitable incubation temperature.
Read these three parts of the label
1. Milk composition
Note the fat and protein values and whether the milk is cow, buffalo or a blend. Compare values on the same basis, such as per 100 ml.
2. Processing and storage
Look for pasteurised, UHT and homogenised wording. Read storage instructions both before and after opening; they are not interchangeable.
3. The ingredient list
Choose plain milk rather than a flavoured dairy drink. Record added ingredients so that a change in formulation does not become an unexplained change in your yogurt.
Full cream, toned or lower-fat?
Fat contributes richness, while milk proteins and other solids also influence the set. Full cream can suit a richer bowl; toned or lower-fat milk changes that balance. Judge the finished result after refrigeration rather than comparing a warm batch with chilled shop-bought dahi.
Do not read “toned” as a brand name or assume “whole milk” overseas is identical to an Indian full-cream pack. Compare the actual label in Mumbai, Dubai or Singapore. A brand may sell several different milk formulations.
What does homogenised mean?
Homogenisation makes milk’s fat droplets smaller and distributes them more evenly, helping prevent a separate cream layer. It does not mean fat has been removed. Non-homogenised milk may develop a cream layer even when the overall fat content is similar.
Pasteurisation and homogenisation answer different questions: one is a heat treatment; the other changes how fat is dispersed. Check both rather than treating the words as alternatives.
Can I use UHT milk?
UHT describes a heat treatment, not a universal yes-or-no verdict for every yogurt starter. For Zoh, confirm that your chosen milk and its preparation match the directions supplied with your culture. If those directions do not address your UHT carton, send a photo of the label to support before changing the method.
An unopened carton’s storage life does not become the storage life of yogurt made from it. Once opened or cultured, different handling instructions apply.
A useful first-batch record
- Photograph the milk label and note the batch or opening date.
- Record the milk volume in ml and the starter used.
- Follow the supplied preparation and temperature instructions.
- After chilling, note texture and flavour. Change one variable at a time on the next attempt.
Questions about alternatives
Should I use raw milk?
Commercially pasteurised dairy milk is the straightforward starting point for these guides. Fermentation is not a substitute for safe milk preparation.
Can I replace dairy milk with almond or oat drink?
Not as a direct swap in these Zoh dairy-starter instructions. The starters contain milk, and plant-based drinks need an appropriate culture and method.
Will adding more starter make low-fat milk thick?
Do not change the dose to compensate for texture. Follow your starter’s quantities and check the milk, preparation and incubation conditions.
Background: NDDB’s milk terminology and milk composition and processing for fermented products. Industrial processing parameters are not a home recipe or Zoh-specific method.
