Usually Bulgarian Yogurt is made of cow milk.
In Bulgaria, it had been the custom for every household to create their very own yogurt, but since the process became more industrialised, the Bulgarian people felt that their life-enhancing yogurt was deteriorating in flavour.
To prevent this deterioration, a lot of lactic acid bacteria were isolated from yogurts still being produced by people within the different country regions of Bulgaria. Seven starters that contained the "magic" from the original Bulgarian yogurt were utilised to enhance the caliber of the yogurt being made by the dairy industry.
The wonderful thing is the fact that some of the people original starters for example 5-12, 144-12 and 37-18 continue to be employed for yogurt production today.
A primary reason behind the flavour and health-enhancing facets of authentic Bulgarian yogurt is the fact that it had been originally made by the technique which has always produced the very best of the earth's food ie while using best as parent for the following generation.
Whenever someone inside a village required to make yogurt, obviously they have to first look for a starter. Naturally, they'd make use of the tastiest, most desirable yogurt they knew of for your starter. So within the centuries of yogurt making in Bulgaria, their yogurt continues to be continually selected for top of qualities. Never was the choice based on what "filler" could provide a manufacturer more dollars for his product or the other considerations which go into a lot of our food production nowadays.
It's thought that a few of the original starters came into being through vegetative means when milk was inoculated through the shepherds within the Rodopi mountains of Bulgaria. They softened the roots of plants for example Christ's thorn (Paliurus aculeatus) and Barberry (Berberis vulgaris Lam) and set the resulting juice within the milk to inoculate it.
With the centuries of symbiotic interaction between both of these wonderful Bulgarian starters Body obtained from milk and something obtained from plants - a distinctive taste developed. Lots of people think that "true" Bulgarian yogurt are only able to be produced through using starter from Bulgaria. The majority of the original starters happen to be patented and therefore are now in worldwide production which means you probably could make something pretty authentic by choosing your source carefully.
