"This one is pretty specific for the region, I think most foreigners would not like it at all. Basically a salty yogurt drink."
"Very fresh and tasty drink"
"Perhaps the most popular soft drink in Armenia is the tan- a mixture of water, salt and Armenian yogurt called matsun. Special attention should be paid to the main ingredient of the tan – matsun. Matsun which is fermented milk product is widely used in the Armenian cuisine. Matsun has the consistency of yogurt, so it is difficult to sort it as a drink. This dairy product is an excellent dressing for salads and a basis for various sauces. Every housewife knows the Armenian tan recipe: for the preparation of the drink you need to take about a liter of matsun, give it a good whip with salt, then stir with a spoon, gradually adding water. The amount of water depends on your preferences: the less water, the thicker and tastier the tan! It is desirable to drink tan chilled. Another tasty variation of tan preparation is mixing it with various finely chopped greens, spring onions, and diced cucumber. And here you have Armenian okroshka! It is worth noting that tan and matsun, in general, is not only delicious but also a very useful product. Tan without added salt and based on mineral water, helps to reduce and regulate high blood pressure. Matsun due to the high content of various bifid bacteria helps to improve the functioning of the gastrointestinal tract and normalize digestion."
