We must be careful with this packing. If you can't find the production license number or company name, most of them are made by small factories. Now many people make instant coffee, and the cost of instant coffee is low. Because it is mixed powder with many additives, it is difficult to distinguish after mixing, which gives producers space. The taste of mixed coffee is "instant coffee". In particular, this kind of tin coffee, which looks like a barrel, is produced in many small workshops. If you like to drink instant food, choose Nestle Maxwell, a well-known brand, with at least quality inspection and production license.
