Thanks to the generosity of
MaineYooper , I conducted my second comparison cupping.
KU 9.3 @ 93C (199F) 8.25g 150ml (1:18x):
Coffees used were:
1) Atomic Coffee Roasters (Peabody, MA) - Simple Summer - light roast
2) Jim's Organic: Papua New Guinea (Korofrigu region) - light roast
Bean Observations:
1) Lighter color, smaller beans
2) Much darker color, larger beans
Grind appearance and fragrance (smell just after the grind):
1) Tomato, berry, lighter grinds. These beans were definitely light roast by the relative difficulty to grind them.
2) Earthy, darker grinds. These beans were so easy to grind by hand. I definitely put these in the 'medium roast' category, not the 'light light' category.
Aroma (after breaking the crust):
1) As with previous cupping, the floaters dropped before breaking the crust, so there was very little skimming to be done. Vegetable aroma. Lighter liquid. Tomato aroma at the 20+ minute mark.
2) Earthy aroma. Darker liquid. Caramel aroma at the 20+ mark.
Tasting notes:
1) Berry (blueberry?). Lighter body.
2) Earthy. Baker's chocolate? More body. Darker.
General Notes:
I decided to try finer grind than last time (KU 9.5) which made one light roast more vegetable than normal. I was originally going to do KU 9.2, but when I saw how dark coffee (2) was, I dialed it one click coarser at KU 9.3 to hedge my bets and not over extract the coffee. Coffee (2) was not bitter at KU 9.3 for this dark of roast, so this was a good grind setting for this cupping. I may have been fine at KU 9.2. I may try that next time. Coffee (1) was good at KU 9.5 and KU 9.3 cuppings. I stopped the tasting by 22:13.
