An update to my perlinParticle02 code: Now, rather than generating three buffer images for the x, y, and speed perlin values, it calculates them on the fly. This has the added advantage of being able to animate time, which you can see in the above movie. However, it's also exponentially slower. This movie took about a second a frame, or ten minutes on my 5 year old laptop.

Over the years, I have asked a few farmers from Brazil, along with importers and exporters, about how coffee is processed here, but until this visit I did not understand the exact methods of the processing.
The first thing I learned is that every farm is different in how they process. The second thing I learned is that, although different, many farms call what they do by the same name.
To give a better understanding I will try to break it down:
The Natural process. Overall, many farms do natural processing (especially in the Cerrado), but it is not like the natural process we find in Ethiopia. Here most of it is tree dried. (I only saw one Microlot that was picked ripe and then dried in the sun.)
Pulp Natural is also very confusing here. The reason being that many farms also have a demucilage machine, which can take off a certain percentage of the coffee fruit after pulping. The percentage of mucilage is dependent upon how the machine is calibrated. Some farmers take off 0% and others take off 100% percent. It all depends on the farm. Most places I visited took off quite a bit. You can tell by looking that the parchment color as it is being dried. The more yellow and rustic, the more mucilage that was left on.
Washed coffees are not very common, but a coffee that has been demucilaged at 80% or higher—in my mind—will taste more like a washed coffee than a Pulp Natural. I saw one farm that actually had fermentation tanks that did an odd blend of Pulp Natural and Washed processing.
Over here is a recap and my short notes:
Natural: tree dried = very common
Natural: picked ripe and then dried = not common
Pulp Natural: 100% of mucilage left on and dried on patio = not common, hard to produce.
Pulp Natural Demucilaged: anywhere from 10-90% of mucilage is taken off and then dried on patio = very common process, but both very good and poor quality can be processed this way.
Demulicaged: 100% of mucilage taken off = not common
Washed process: Coffee is pulped, fermented, and then dried = Not common.
A good note to all of this is each farm also changes their focus for processing day by day. For instance, if a lot of ripe cherry is harvested (like you would find early in the harvest season) then a lot of farms choose to make that a Pulp Natural. A lot of tree dried cherry generally means it is later in the harvest and that of course will be a natural.
I told you it was confusing.
