Mongolian coffee, it seems that Mongolia doesn't produce its own coffee, but you may have bought coffee sold in Mongolia with zero tariff or 5% tariff, so you can buy coffee from all over the world. You may have bought coffee from a certain country, so don't worry, the coffee you bought is definitely good, because Mongolians don't sell coffee from China for fear of melamine. So I think, as long as it's not expired, drink it. I often buy Italian coffee from Mongolia.
