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. |

| Rwanda Butare Bourbon WP Decaf | |||||||
| Country: | Rwanda | Grade: | Estate Grade | Region: | Butare, Western Rwanda | Mark: | |
| Processing: | Wet-Processed | Crop: | October 2008 Arrival | Appearance: | .2 d/300gr, 16-17 Screen | Varietal: | Bourbon Cultivar |
| Notes:This is a Butare-region coffee from western Rwanda, and the coffee is nearly pure Bourbon varietal from a range of 1500-1800 meters. My flavortite Rwanda lots in the past years have been this area (Buramera in particular), and the fact that it is from such high altitude, and that is traditional Bourbon culitivar ... well those are the perks of Rwanda coffee. The country was planted extensively in Bourbon and was not an innovative coffee-producer in the years when all the new hybrids were being pushed ... a blessing in disguise that they missed this trend. There was extra selection done to prepare this lot for export. This lot was specifically hand-prepared at a milling factory that has a UV cleaning (color sorting) and grading facility. UV also detects any potato-taste in coffee, a problem that can sometimes occur in Rwanda lots. Then it was sent for decaffeination using the non-chemical water process method, and survived with great Rwanda cup character. The cup is very balanced, like it's non-decaf counterpart, with pastry-like sweetness in the dry fragrance and floral aromatics when wet. The cup is, again, balanced, well-structured. At a City+ roast it has lively acidity, tangerine citrus notes, a delicate floral component, and finishes with a hint of pancake syrup (you know, the fake stuff). At FC roast, I made one of the absolute best Single Origin decaf espressos I have had with this coffee! I highly recommend it for espresso uses, or as part of a low-caf espresso. |
|
||||||
| Intensity/Prime Attribute:Medium intensity /Classic balanced cup with citrus accents | |||||||
| Roast:City+ to FC. I prefer the medium City+ for brewing, and FC to FC+ for espresso. | |||||||
| Compare to: Balanced brightness, and doubles as a great decaf espresso coffee. For more info on the Water process and other decaf methods, see my article: http://www.sweetmarias.com/health.eco.html |

| Processing: | Wet Processed | Crop: | October 2008 Arrival | Appearance: | ..2 d/300gr, 16-17 PB Screen | Varietal: | Arusha, Bourbon |
| Notes:Coffees from South Tanzania have a few advantages that result often in better cup quality. It might not be romantic to list "transportation" alongside "terroir" as major factors in cup quality, but indeed it is. With coffee, it matters little loamy the soild was, not high the elevation of the farm, how ripe the cherry was when harvested, how carefully it was wet-milled, if it gets packed in a container that gets steamed for a couple weeks in a humid port city. Typically, Tanzania pebearry lots were from the northern districts near Kenya actually have a shorter trip to port in Dar Es Salaam, but somehow suffer so much more in the process. Southern district coffees from Ruvuma province, collected and milled in cities of Songea and Nyamtimbo face a longer trip but miraculously survive it better. The key might be logistics, or the fact the coffees are better treated in drying, and in particular the rest period when coffee remains in it's parchment shell for 30-60 days before being hulled, sorted, measured for density, and bagged for export. This period is crucial to allow moisture to be distributed evenly in the coffee, to achieve physical stability in the green seed. For this decaf lot, surviving the trip is just the first challenge. Once here, it is sent down to the water process plant in Mexico to remove the caffeine using the non-chemical, water filtration method. While this (and all) decaf methods are traumatic to the coffee, and to the final cup quality, a few survive it like champs. This Tanzania PB Nyamtimbo Ruvuma is one of them. The acidity (the bright, effervescent, lively quality in the cup) comes through as if it had never been decaffeinated, even more so than some of our recent excellent Kenya decafs. The dry grounds has a lightly fruited cherry scent, while the wet aroma has a light molasses and caramel sweetness. (Molasses sweetness is often a product of the decaf method). The cup has a fruited, flame grape sweet flavor, turning to gingerbread in the aftertaste. It has fairly light body overall, and quite a sustained aftertaste. |
