How to prevent greek yoghurt getting more sour
My mum has always liked making home made yoghurt, but the major problem with it has been the fact that it gets more sour over time. The night after she makes it the flavour is usually a perfect balance between creaminess and sourness (very much like the flavour of many supermarket greek yoghurts).
The only problem is that whereas supermarket yoghurts flavours do not change, our home made flavour does, and we have no idea what we can do to it to stop it doing so. Any ideas please?
Best Answer
Unfortunately (actually… let's say fortunately) homemade yoghurt still contains a lot of active cultures which will continue to work even after you refrigerate it. Refrigeration will slow that process down, but it will not stop it completely.
There are two (well, three) things you can do to avoid that tart flavor from the active cultures at work:
Refrigerate a portion of the batch early
When you (or rather, your mum) is making a batch of yoghurt, refrigerate a portion of the yoghurt before it is quite "done" and let the rest continue as normal. The refrigerated portion will continue to finish in the refrigerator while you consume the portion that was allowed to achieve that "perfect balance". You can estimate how much yoghurt you should set aside by noting how much you have have left over when it starts to become too sour for your taste. The next time you make yoghurt, set that amount aside (in the refrigerator) to be consumed after the first batch is gone.
Freeze what you cannot consume quickly
This option is far from ideal. You can slow or just about stop the fermentation process by freezing a portion of the yoghurt just after you make it. Unfortunately, when yoghurt is frozen then thawed, it can separate and become somewhat watery and grainy. Sometimes you can mix it back in, but it may not have that wonderfully creamy consistency of the original. You may have to try it and see. Defrosted yoghurt will still be healthy to consume, but some believe you will lose much of the health benefits as the live bacterial cultures can be destroyed by the freezing process.
Or keep it as a frozen treat
You may also consider not defrosting the frozen portion at all. Some people actually enjoy the experience of frozen yoghurt as a healthy snack alternative. If you consume some fresh and some frozen, you can think of it as two treats in one.

How do you make Greek yogurt less sour?
To make greek yogurt less sour, the best options are to sweeten the yogurt with natural sweeteners like honey, stevia, pure fresh maple syrup etc. My favorite sweetener to go with yogurt is always raw honey.Why is my Greek yogurt too sour?
Again, this is a direct result of the acidic environment created by fermentation. When casein proteins found in the milk are exposed to the highly acidic environment created by bacterial metabolism, they begin to curdle and form the thick yogurt texture you know and love.How do you keep yogurt from sour?
Opt for whole milk over toned or skimmed milk which will help create thicker and creamy curd. Make sure the culture that you use is not sour; otherwise it will make the curd sour too.How do you get the tartness out of Greek yogurt?
Honey. If there is one thing that can make you forget about the bitterness of Greek yogurt, it's honey. Its texture combines perfectly with the thickness of the Greek yogurt and adds a very natural and sweet taste to it.Yogurt Is More Unhealthy Than You Think
