^^^It's 100% Arabica beans. I have been buying from the same Shopee seller (Pinoybrew) for several kilo packs now. They are all medium roast until this one. Too bad the delivery arrived after I have prepared my regular morning cup.
Edit: I just prepared my first cup from that bag. I used the same grind settings for the medium roast and it came out much finer. As expected, it tastes much bitter. If you like Dunkin Donuts coffee, it tastes like it although much finer taste.
