There is no specific standard for Blue Mountain, because different baking degrees, different estates, different water content and other reasons will affect the flavor, but the export quality of Blue Mountain for regular tooth buyers will be higher, just like the uniformity and altitude of beans.
In terms of flavor, it has a strong fruity and sour flavor, because high quality will be more balanced, clean and smooth. I like to bake raw beans at home, so pay attention to its taste is not specific. Why do I say it gives me the impression of good quality and balance? Besides, the blue mountains are not the best, and the roses are higher in summer. It's just famous, so I don't have to get my hopes up.
