Ok, I tried roasting 1/2# of 6 oz of Daterra Sweet Collection with 2oz Ethiopian Yirg. at 1/2 P3-C. I had to hit the + sign a few times...otherwise it wasn't going to make it to the first crack. This time the voltage was lower all around which probably didn't help the range was from 119 down to 113, but averaged about 115V. This roast is probably too light. It is an even light brown. I would really want it to be a brown that would be between the two roasts. I wonder how these will taste after 4 days and the difference between the two. I wonder if it would it help to mix the two batches. Trial and error...maybe eventually I'll get it. So far I am disappointed in how they look.

Yesterday, I roasted 4 oz Brazil WWP, 1 oz Mex WP, 1 oz Guat WP (these are decaf beans) @ 1/2-P3-C it roasted well with no adjustments.

Otherwise, for my husband, lately we've been roasting 12 oz Deterra Espresso Yellow or Bourbon @ 1-P3-C....usually needing to hit cool with somewhere around a minute left.

I should add that several months back I had been having problems with our voltage being too low and inconsistent. I called the power company out to fix it and have since been staying between 123 and 115 with an average around 121...but this is winter in FL and once everyone is using A/C again it may be at 118 average voltage. Anyway, I think that there has been an improvement and that the higher average voltage has helped with the consistency of the roasts. When we were using A/C in the fall, I tended to roast in the mornings. Lately, that hasn't been as important.

A good high voltage is important for consistent results. Starting with a good high voltage usually requires no adjustment in my decaf at 1/2-P3 C. Since the weather in FL is hot again that means I have more luck getting high enough voltage by roasting in the morning. With none decaf we usually have to hit cool with 39/40 sec left at 1-P3 C.
Voltage plays an important part in successful roasting with the Behmor.
