Wet Processing

A coffee processing method which involves “washing” the coffee beans to remove the coffee’s fruity material while the coffee cherry is still moist (e.g., just after picking).

Removing the Parchment and Mucilage

More specifically, wet processing is a method of getting the parchment off the coffee cherry (fruit) by first removing the pulp from the coffee bean.

Next the coffee cherry’s mucilage is removed through fermentation, and finally the beans are dried, either in the sunlight or using forced-air drying, to achieve a final moisture content of about 10.5%.

Characteristics of a Wet Processed Coffee

Wet processing in general is said to produce a clean taste in the cup of brewed coffee, and also helps to ensure a shining, bright acidity. One undesirable effect of wet processing, however, is that it causes the coffee to lose much of its body.

Pulping and Fermentation

Wet method processing usually involves placing the beans into water for softening and then mechanically de-pulping the beans using a pulper. Next the coffee beans are placed into a fermentation tank to remove the mucilage.

The length of time that the beans are left in the fermentation tank – usually from 8 to 24 hours – depends on various factors including the temperature and elevation, of the site. At lower elevations it only takes about 12 hours in the fermentation tank, but at higher elevations it may take 24 hours.

Rinsing and Sun-Drying the Coffee Beans

After the coffee beans are washed (flushed) again with clean, fresh water they are dried either out in the open (see Sun-Drying) or in large, heated rotating cylinders in mechanical dryers (see Drying).

Green Coffee Beans

After a coffee crop is processed and then sorted and grades, most of the coffee beans are usually bagged in 100-pound coffee sacks which are in turn sold on the world market as green coffee beans (milled though not yet roasted).

Selective Picking for Wet Method Processing

Wet processing is typically used on coffee beans that are selectively picked (only the ripest coffee cherry are picked), and not on coffee beans which have been strip-picked (all of the coffee cherry are picked off a branch at the same time).

Wet method processing is also known as the washed method, and is commonly used for top premium gourmet coffees.

I’m amazed, I have to admit. Seldom do I encounter a blog
that’s equally educative and amusing, and without a doubt, you have
hit the nail on the head. The issue is an issue that too
few folks are speaking intelligently about. I’m very happy I stumbled across
this in my hunt for something regarding this.

Mexicans must go back to Mexico so white people can have their jobs.
Having adults around in a kid’s party is helpful, if there are activities that require adult supervision. Everyone loves a good party, but clearing
up afterwards is not so fun. As soon as the protection and set aside agreement is
signed, the parties should immediately discuss a realistic plan for permitting the dealership to workout of its problems.
