Decaf Coffees
Follow this link for more information on decaffeination processes. For more information on the Natural Decaf (Ethyl Acetate) process, here is an article. For more information on CO-2 Process, check this out. Good news or scarey as heck? Geneticists are working on a plant that will grow coffee with no caffeine content, thus needing no processing to remove the caffeine as all decaf is currently. Is this good? It means no factory process to remove caffeine. It also could mean contamination between natural unmodified trees and modified ones. Coffee is very complex in terms of it's chemical makeup: it has over 800 compounds contibuting to the flavor, more than any other beverage. Can you turn off one genetic attribute and not affect others? We shall see the results from the current research work (being conducted in Hawaii). |
The Decaf Processes: Green coffee is decaffeinated before roasting. This process changes to color of the green coffee: it varies from light brown (Natural and CO-2) to very dark brown ( MC and Swiss Water Process -SWP- decafs). We are listing a new, exciting decaf coffee as WP -Water Process ... new because it comes from a source other than Swiss Water and exciting because the cup quality is superb. Decaf coffee roast faster than non-decaf coffees. Part of the differences in how a decaf roasts are due to the physical changes the coffee has experienced in the decaffeination process. But in an air roaster it is also affected by the smooth surface of the bean, which allows more air to flow around the coffee without transfering the roaster heat to the bean. This smooth appearance is due to the fact that decaffeination removes much of the thin chaff silverskin from the outside of the coffee. As a plus, decaf produces little chaff that will collect in your air roaster chaff collector. Because of the darker color of decaf coffees, especially the very dark SWP ones, it is difficult to roast decaf by judging the color. It's best to pay attention to the sound of the cracks and the roast aromas. It takes a few roasts to understand these sights and smells, but its a fun process and even if the coffee comes out a bit too light or too dark, it will still be freshly home roasted! And that beats most store-bought coffee any day! Decafs can have a lower 1st and 2nd crack temperature, and can progress faster between the cracks. You can also see oils emerge a few days after roasting a decaf despite the fact that you did not reach 2nd crack (the usual reason you would see oils emerge). This is because the bean structure of a decaf is more fragile after the process, and the cell walls in the coffee tend to rupture at a lower temperature, allowing oils to migrate to the surface. As with all coffees, oils stale when exposed to oxygen, soit is preferred that your coffee is not oily on the surface ... but for darker roasts and decafs it is unavoidable. |

Notes: People have requested that we offer a pre-blended espresso, a decaf counterpart to the Espresso Monkey blend. Working under the codename of the "Donkey Blend" (don't ask how all these ridiculous names started ---I think it was George's fault) we came up with this. It is intended to be used several ways. As an all-decaf espresso blend I wanted it to work well under a wide variety of roasting conditions, in terms of both lighter Northern Italian type espresso roasts (the equivalent of a Full City to Vienna Roast) and the darker Southern Italian type roast (roasted to a French roast). I also wanted a good espresso from both air and drum roasters, and I wanted good crema. This is a lot to ask from a decaf, but I think this blend works very well. While origin tastes are muted in decafs, I think the bittersweet roast tastes from this blend are very good. My second focus was having the blend not have too much character so that it can be used as a base blend for a "low-caf" espresso. This means it should work well as 50-75% of your blend where you add other caffeinated coffees to give more aromatics and flavor: my choice would be a Ethiopian Harar, or a Central American (see our Blending Basics article for more). | |||||

Roast: As with all decafs, remember they roast faster and have the propensity to get away from you and end up darker than you expected. So attend to the roaster and stop the roast manually if possible to get it just right. Roast preference with espresso is up to you. I personally prefer the lighter N. Italian roast -just a bit mire than a Full City. | |||||
