Default Re: Coffee Roaster for WFO

I took a sample of roasted coffee to an experienced coffee taster....he was "Brutally honest", but had some good suggestions.
1. I have been roasting too hot/too fast. I usually have an active flame going, but it turns out it burns the beans outside, and doenst roast inside.
2. At "first crack", lower the temperature. For a WFO, that means move the beans closer to the entrance down low where the cool air is coming in.
3. They are roasting more on one side than the other.

I am installing a digital thermometer in my roaster with a thermocouple that extends into the basket. Also Im going to make some sort of "agitator" to mix the beans more....also will probably do something like TropicalCoasting and mrchipster suggest (above). He also said that he believes my beans are over a year old, based on what he knows about the crop cycle. There is nothing wrong with that, but this didnt surprise me. I have some beans coming in this week from Sweetmarias.com. slightly beter prices, but longer to ship.

I fitted my coffee roaster with a digital thermometer. Now I can monitor the temperature inside the basket while roasting. I roasted a batch with a modified technique. I kept the temperatuer at about 500F until the first crack...then moved the beans toaward the entranceway of the oven where temp was about 400.....beans roasted slower and evenly. Coffee tastes much better.

Ok...Here are a couple of pics....I got the digital thermometer from amazon. You also need to get a thermocouple that can handle the heat. Below are the part descriptions from Amazon:

1. Digital Thermometer (Amazon)
AGPtek Dual Two Channel Digital Thermometer 2 K-Type Thermocouple Sensor 1300C 2372F

2. Thermocouple (6" probe with 2 meter long wire): Amico K Type 15cm Long Probe Thermocouple Temperature Sensor 0-400 Celsius


Total Cost: $32.50

I used steel hose clamps to mount everything....also rigged up some brackets out of a piece of brass. I dont need to tell you this, but make sure everything can handle the heat.

If you can get a copy (mine was courtesy of the local beer store) Imbibe magazine sept/oct 2013 issue has a good article on wood-fired coffee roasting. The author favors longer times (22-24 minutes) at lower temperatures. His brother is the master roaster for Mr. Expresso which does 1 million lbs per year wood-fired. He stays at about 500 degrees....

I just roasted some incredible coffee today. I am surprised how few people recognize the utilty of the WFO beyond pizzas. Since I started roasting my own coffee, I now wake to some of this best coffee I have ever had!!! The WFO makes an amazing coffee roaster. It takes some skill though, but when you begin to master it....WOW!!!
