This bar has one of the best textures I have experienced so far. It is ground a bit on the fine side with no noticeable grittiness, it gives a somewhat dense coating on your tongue yet still feels very smooth. The melt is extremely satisfying.
Flavor wise, I would say this bar is definitely a sensory experience, yet there isn't a single distinct strong flavor, which is perhaps why many describe it as mellow or mild. There is a slight astringency yet sweetness, and noticeable tanginess which gets more noticeable if you chew it or work it with your tongue. You can feel some hits of roasted nuts and citrus, and if you chew it there is sort of an acidic savory flavor (cheesy) that is common to Criollo beans.
Overall, I think this bar is really great value and a great 100% Criollo bar. Definitely also recommended to introduce people to 100% bars.
