I know, I know, this topic is an old friend from our SM list, but maybe a new approach. I ordered few days ago some coffees, and asked Maria if she could send the Color Roast Post Card. Maria told me that they decide to 'phase out ' the card because the issues with the reproducibility (aging) of the card, and they are investigating reliable alternatives to the old post cards. I have access to same Pantone books (Color Classification System) , and wondering how to find a proper way to match City, City +, Full City, to their equivalent Pantone Numbers. The closest that I got (So far), is: City + closer to 462 C or 1545 U (Coated Color) On the Pantone web page, we can find a 'screen representation of the colors, and their light and darker equivalents (Paint Interior Matching guide, use the color 462 C on the Pantone Number box), unfortunately the 'screen representation' is not accurate at all (the paper chips are much, much better) One idea will be to order the specific 'chips page' with the color that we want to match, I still need to match the other key Roasting colors, and then get the full equivalent list roasting nomenclature x Pantone Name x Agtron #. (I just hope that when I have all these matches, they will be inside a single Pantone chips page) Each 'chips page' from Pantone book cost (at the website) US$ 7.50, that is not that bad (ok, ok, I know 1 lb of coffee, that we will not drink!) Any experience from the list on this approach?

What we had done a long time back with help from , jeez, I can't
remember who did it, was match the SCAA roast color discs to paint
swatch cards available at Home Depot. The idea is people could go to
a nearby Home Depot and get the same set of color cards (and of
course, buy something, because it's only fair). I could try to find
out the results from that work, if anyone is interested.
We really want to produce a printed series of cards with roast
images, something you can hold by your roaster and reference. Going
from digital image to offset print has been the issue. Dark browns
are very hard to reproduce correctly. We are going to do this again,
soon, by doing extensive proofs to make sure we get the prints right.

Hi, I just had a thought, which might work! How about taking a series of beans at the correct roast and have them embossed in resin, like they do coins, bugs, etc. Maybe 2 or 3 beans at the same roast put side by side or make a circle for better viewing. Don't know the cost associated with the production, but I have seen home kits for doing such projects. A real live bean is better than a picture and it would last forever!

I believe it was Dan Bollinger (of "I had the best cup of espresso..." tee-shirt fame) who distributed the color samples. It was definitely based on Sherwin Williams swatches. I have a set here somewhere. |
Interesting idea. I would buy something like that (or make something like that given the proper skills and materials). -- Ryan M.

I have mixed feelings with color cards. They might be helpful for a beginner but they might also add confusion if because they are a beginner they don't understand that some beans will tend to color differently and at different times. It's also important to understand the relationship between surface color and ground or inner color. I suppose it could be used to add the color numbers in a log record. It could be quite helpful for us to use to communicate when discussing a specific bean. It can help diagnose some roast issues.

I see it for what I perceive it to be- a tool. Any tool can be used properly or improperly. The solution? The manufacturer sends instructions with lots of caveats! I do certainly see your line of reasoning though. However, for a beginner- some direction is better than none. In the end, taste and quality will guide the beginner to advanced roaster irrespective of which tools they chose to start with. Assuming they are actively learning that it (This is the part where where RayO comments on changing variables one by one to achieve mastery). -- Ryan M.

I was sort of thinking the same thing about color variation. Also, my impression is that different roasting methods (e.g., drum vs. air roasting) result in different bean colors for a given level of roast.

Yes it does. This is why you should compare ground coffee color instead of outer surface color.

"A real live bean is better than a picture..." and it's Developing, not frozen in time. What resin have you found that stays water clear and does not adsorb or react with the bean pigments as it cures, shifting color by itself or leaching the bean colors? Exactly what about "Different Pigments, different light source color temperatures, different colors used as primary colors, color blind individuals-" that dooms the proposed system to failure seems to be unimportant? A few minutes' oxidation would cause a quantifiable color shift if the color be read with a color densitometer. All silly when the cup is the bottom line. Flavors, not numbers...

I still think a reference set of roasted beans is a useful idea. I envision: 1 oz packets of the minimum roast and the max SM recommended roast could be available for each coffee origin. Bruce Garley Stillwater, MN Vivir con miedo es como vivir a medias. |
"I envision: 1 oz packets of the minimum roast and the max SM recommended roast could be available for each coffee origin." And about how much do you envision paying for them? The labor cost would hardly diminish to split out the 1oz samples. Add to that the fact that they do not currently roast to the minima and maxima for commerce. Does that change the vision any?

" Dark browns are very hard to reproduce correctly." Maybe with the digital state of the art, it's difficult, but I saw some excellent, dense brown gradation proofs from an analog laser scanner- that I repaired, not operated, on Kapiolani Blvd in a western city. They also had a Brobdingnagian LogE Apollo process camera that nobody else seemed to be able to size and focus. (My dummy load for the scanner's 20v, 50A power supply was a full spool of 12 Ga THHN solid wire.) Densitometers make "very hard to reproduce" very easy to reproduce. In fact, one of the Big Box stores uses a form of densitometer, with which they can read your color sample and supply paint that will dry to exactly match the sample color. Maybe they would read your bean sample then have you choose from several scans. Roasted beans are not monochromatic... Then your roasting would depend greatly on the color temperature of the ambient light. The northern sky is about 7500K, many jewelers use that kind of light. I picked up a slew of 8000K ultra high intensity LED's on eBay, and Office Depot sells some small 9 LED flashlights for cheap. Blindingly bright, and the color temperature is high LED's won't dull or age like incandescent lamps or fluorescent lamps. Cheers, Mabuhay -RayO, aka Opa! Could always pick up a Cosar SOS-40 or MacBeth densitometer on eBay- boat anchors but all good!
