Are there any non self-serving websites that rate coffees? Things like cost, flavor, perhaps countries of origin etc.?
Reviews of raw or roasted coffee?
Roasted.
Are you asking about small local roasters, fancypants “gourmet” coffees sold online, or national brands sold in supermarket chains, Walmart etc.?
Coffee Bros of New York uses a rating service and post it next to their products. I buy a single source Ethiopian from them that has a 92% rating from Coffee Review.
