Batch 4. 100g for 12m at 52%. First crack (after 4-5 outliers beginning at minute 3) at 7m. Net loss of 15g (15%). I was aiming for a medium-er roast since the acidity was a bit much. Next time, I’m keeping everything the same, but I will try to use a lid and stir with occasional tossing motions for the first 3 to 5 minutes.
