We are exclusive representative of ISTAK in asia-pacific.
It's product in Iran for around 7 years and people used to drink this kind of drink which is so healthy and put a side most of coke and soft drink.

regards to equation I have to say that yes same equation as beer but in this process stop it before alcohol creates but all other non alcoholic drinks go to the end of process and then withdraw alcohol with chemical material.

this product is in 10 flavors : original, lemon, peach, pear, apple, tropical, mango, pineapple, pomegranate, strawberry.
