great rich ethiopian aroma, definitely a bit sour, grind 70 is probably too coarse? combined with 15 ratio (more of a proper medium roast recipe?). surprisingly bitter and roasty finish though - is that the oolong? bit unbalanced, but intense sharp melon sweetness. leaning more blue as it cools. mellows out a lot. the acidity balances out with the sweetness more, bitterness almost disappears. Super tea-like, but thick.
