I'm excited to be participating this month, having picked up two pounds yesterday. Fresh crop Kenyas are lovely, both in the roaster and the cup.

I'll be exploring a few areas.

1) Just how aggressive can I be with the charge? Kenyas are notorious for withstanding high heat application, so I'll see how far I can push it.

2) development phase and solubility - I've been having good results cheating Rao's 20% rule with drip roasts. We'll see if that approach works for this bean.

3) how insulation affects the roast on the Quest - I've just installed insulation and run through several roasts with it and had good results. We'll see how that affects this bean. I'm pretty optimistic given that fresh Kenyas demand tons of power during first crack start's endothermia.

Cheers,

Jan

as in doing less than 20%? I've been doing the same and getting better results

For drip, I'm liking around 15% with Colombian and Guatemalan coffees. There is a slight loss of solubility as measured with a refractometer. For espresso, I'm sticking to 20% and dropping 3-8 F hotter.

By the way, this doesn't necessarily contradict Rao's ideas since an M3 or Huky is more conductive than a 5 kg + double drum production roaster.

I'm doing much of the same for drip...Glad to have you on board!!!

I roasted a batch of the April R&L Yirg today as a warm up for this Kenya.

I completely changed my approach and took it to 14% development, using a curve somewhat similar to the one Tom posted that month with a lot of momentum going into 1C. So I'm on board with you guys here - let's see how it goes with the Kenya!

order placed also - the FOTR competition and discussion has renewed my interest in the RALT discussions ... hope they are as enlightening.
