www.barringtoncoffee.com: truly great coffee roasted to highlight its inherent quality

Have your home roasts assessed by Jim Schulman (another_jim)

Postby oconee on Thu Mar 31, 2011 10:36 pm

I recently took Jim up on his generous offer to assess my home roast. He was nice enough to let me send two different beans/roasts and assess both and provide feedback. My reason for seeking this input was that after about two years of home roasting and making espresso (and two different equipment set ups for each) I finally felt like I had gained sufficient consistency to implement suggestions made by an expert. I roasted a single origin (El Salvador Finca La Florida) to what I consider a lighter roast that I am using in an Aeropress as well as SM Monkey blend roasted darker for espresso. As instructed, I sent samples of the roast as well as the green coffees to Jim. He froze my roasts, roasted the greens and then compared his roast to mine. His thoughtful observations on where I was at in my roasting as well as suggestions for improvement and learning will greatly assist me as I try to continue to improve. I did make the suggested donation to Coffee Kids, and reading about that charity was quite interesting. I can certainly recommend to other roasters who are not experts, and wish to gain insight into their technique, that they take advantage of this valuable service. As always, I appreciate Jim, Dan and the other expert posters on this site for the knowledge and entertainment provided by their posts and discussions (and even their disagreements).

For those who may have somehow overlooked it, Brian refers to Jim's offer in Have Your Home Roasts Assessed.

Curious: how many of you have made use of this generous offer? FWIW, this is the best time/$ spent to improve your roasts for easily 99% of us here. If you're serious about improving, this is a no-brainer.

As for me, I've recovered from the near burn-out caused by the 2nd annual HB competition, but haven't added any new beans to my collection since (I far too aggressively stockpiled the past 2 years!) As soon as the Ethiopia Nekisse Green arrives, or whatever else I buy in 5lbs+, I'll be taking advantage of Jim's assessment.

So far, not a lot of takers. But for a Nekisse roast, I'll say whatever you want me to (non-Homer drool smilie here).

BTW, Rama won the homeroasting competition; so he should be judging, not submitting.

I guess all that coffee would explain why you're posting at 1:28 am. I had missed this offer and plan to take you up on it. It's kind of like going to the doctor though. I'm generally pleased with my roasts but fear the unknown. In other words, I'm awfulizing. I fear you'll tell me my roast tastes baked or stewed or otherwise unpalatable. Then I'll discover that not only are my roasts bad but so are my tastes. I've got too much invested in this hobby both financially and emotionally for that to happen. Still, I think I've got to do it. Do you have any recommendations about the coffee one should use? I like Sweet Maria's Moka Kadir - that's what I'm leaning towards.

Send me a successful roast of one of your usual coffees, along with 150 grams of the green.

This makes a good point. There are two reasons people send out roasts to be tried.

The first is that they are not getting the taste they want or expect, and don't quite know how to describe the problem or fix it. Having your roast tasted by someone experienced is the best way to solve this.

The second reason is what you describe; you are generally satisfied with your roasts but wonder if you could do better. Here you have options. You can order highly regarded coffees similar or identical to what you are roasting yourself and see which you like more. For instance, Klatsh, Metropolis and PT's sell green and roasted versions of their espresso. You could enter the annual HB or other competitions and see where you stand in relation to the community. Or you can send the roast out for a check up.

All of these options are good if you got into home roasting in order to roast top rated, state of the art, coffee. But if you got into home roasting for other reasons, for instance, to supply friends and family with inexpensive but good coffee; then this sort of checkup may not work -- it could be like sending a bowl of your prize chili to a cordon bleu competition. The best way to avoid this sort of misunderstanding is to say exactly how you use the coffee, what you like about, etc. Then I can taste and make comparisons based on the standards you want to follow rather than my own.

Would it be possible to send coffee from norway or do you think shipping time will be too long? I can vacuum pack the roasted coffee. It is light roasted coffee for drip-brewing.

I'm willing to do it; but I don't know if it will work. If what I get tastes flat; I can't see how I would distinguish a roast that took too long from coffee that staled in transit. Therefore, you need to roast something that tastes good seven to ten days out. A light-medium roast for espresso will usually work; but with a brewing roast you should make sure of this before sending out the coffee.

Vacuum packing definitely helps, express shipping would even more.

IMHO, there's still value in giving it a try if you don't have any local options. You could do either:

A- roast two batches identically, vac pack them both. ship one to Jim ASAP. When it arrives, both of you open and taste on the same day. It wouldn't be so much a roast assessment as a "palate calibration", which is of great value too.

or

B- roast and ship to Jim ASAP along with some green beans. Jim freezes the roast beans on arrival, roasts the greens and lets them "age" the same amount of time as the shipped roast. Then taste them side by side. Not ideal, but its something.

Or even a combination of A and B.
