To put it bluntly, single product coffee is a single variety of single origin. Single-product coffee must be brewed in a single-product way, such as a filter, such as a siphon. Mixed coffee is to enhance the advantages of single product, mix and concentrate coffee beans from different places, and create deep and uniform coffee according to taste needs. For example, Mi Yuan Coffee's Jinzun and Heizun coffee beans are mixed with coffee beans from different places, and the taste is excellent.
