It’s less acidic than coffee but similarly bitter, so while I drink my coffee often black and without sugar for the chicory I find having a sweetener almost a necessity. This is a blend with rye and barley, that makes it more round. I agree with the other commenter that it tastes a bit woody. It has similar earthy tones to coffee, but I wouldn’t say it replicates well coffee. It’s its own thing.
The mug is form a company, so it just says the name of the company in binary.
