Full-fat cow yoghurt with longer fermentation

Especially for those of you who like your yogurt sour.

The purple yogurt has a longer fermentation to achieve a traditional more sour taste, especially for those of you who like your yoghurt to be sour.

To make it work, we just leave the milk in the warm chamber a little longer. In this way, the heat-loving Lactobacillus bulgaricus develops more and its typical sour character prevails over the soft and sweet Streptococcus thermophilus.

And again: this yoghurt is organic, pasture-raised, non-homogenised, real, with Bulgarian
starters and milk from organic mountain farms.

What determines how sour our yoghurt would be?

Probably you are already aware that harmonica yoghurt is made with live starter cultures from two common strains of lactic acid bacteria (Lactobacillus Bulgaricus and Streptococcus thermophilus) in Bulgaria. They are responsible for the amazing qualities of our yoghurt – its flavor, texture and acidity. The balance between the two bacteria in the yoghurt depends on the temperature and the fermentation period. For example, the Lactobacillus likes warmer temperatures and grows faster at higher degrees. Even just a small rise in temperature can affect the balance in favor of the Lactobacillus. What happens is that the milk becomes sourer like our milk with the purple cap. The Streptococcus gives a milder aroma and a sweeter lighter taste. An example for this is our yoghurts with the green and blue cap. The reason behind this distinct taste lies in the secret of fermentation. We offer different types of milk for every taste preference – either sourer or moderately sweeter, we have something for everyone to enjoy and benefit of.

Why are our yoghurt caps made out of paper?

Because they are fully recyclable. The caps of our yoghurt packaging are made of two layers – outer paper and inner – polyethylene. We have chosen this combination of materials because is much more environmentally friendly compared to aluminum caps. Although it is harder to open, it is worth the effort, we believe.

What's in it

Organic certified whole milk yoghurt with probiotic starter: Lactobacillus bulgaricus and Streptococcus thermophilus.

How it's made

We leaven our yogurt with the two good bacteria Lactobacillus bulgaricus and Streptococcus thermophilus, which stimulate each other in the fermentation process. There are hundreds of different species of both bacteria, each of which gives a different and distinctive flavour to the sour milk depending on the proportion in which they are present.

Lactobacillus bulgaricus is winter-hardy and likes to be warm - even a few degrees above during the fermentation process, and this bacteria will impart a more sour taste to the milk. While Streptococcus gives a more mild flavor and a sweeter and lighter taste. So when we make the more sour milk we let it ferment a little longer in a warmer place than the classic, green-capped milk.
