Make a home coffee roaster by simply using a pan and an oven!

Home coffee roaster is going to be the one process that gives you the perfect cup of espresso. There is no doubt about this, roasting is the most important stage in the entire coffee making process. The stage starts with sorting/grading, roasting,grinding and lastly brewing.

Roasting with commercial or home coffee roaster alike is an art. This is the process that creates flavor and aroma, without it, none of the flavor of the coffee would be avail in the espresso (hmm...there wouldn't be any espresso to start with!).

If the roasting is done badly, it either gives you a tasteless coffee or a bitter coffee, which in my vocabulary is yucks! But fear not, currently there are systems and specific home coffee roaster that really simplified the job that make bad roasting non-existent.


Questions about Coffee

Questions about coffee? Have it answered by the professionals. Examples of some questions: 

What are the considerations for an office coffee station

What are the essential V60 Coffee Brewing tools

Non coffee (but important to coffee) question: What is whole milk

As in all things, there are exceptions. Roasting Guatemalan Antigua beans to high roast will give it body and yet retain its acidity and fruitiness. And high roasting some mexican beans will actually make them taste sweeter.

In this article, I would be showing you the easiest way to roast beans at home, but remember this -a roaster job not properly done would cause extensive damage.

Roasting should be done at 240 degree celius and for a fixed time to get a particular roast. Flouted these rules, results in oil not extracted and underdeveloped flavor.

And if the temperature is too high and the roasting too long, the beans will taste thin and burnt. So, slowly you can see why people are paying good money for those home coffee roaster right?

Now, comes the million dollar question -which is the best home coffee roaster? The range of home coffee maker goes from a small i-roast that have a cannister that holds half to one cup of green beans and costing USD$199 to a drum roaster that can roast 9 oz of beans and priced at USD$ 580.

You can refer to this article: gourmet coffee roasters for some insights on the various home coffee roaster.

A popular home coffee roaster

It doesn't look like much, but this fellow can and had "roast out" many cups of good coffee

Okay, lets see how we can roast some beans with the simplest technique and no complicated tools.This would not be the best coffee roast but with practices, it can still get some pretty good coffee:

The skillet-in-the-oven method

First, preheat the oven to 260 degrees celius.

Then, spread an even layer of green coffee beans in a cast iron skillet and put it in the oven.

Roast it for 20 minutes

For light to medium roast, shake the pan occasionally. The beans will first turn yellow, then brown. You will hear a 'cracking' sound as the remaining moisture bursts from the beans and releases the coffee's aroma.

If you are looking for a darker roast, trim the heat to 200 degrees celius after 20 minutes. Then continue to roast and shake the pan occasionally for another 15 minutes. The timing would depends on the darkness of roast that you desire.

Once you achieve the desired roast, remove the pan and allow the beans to cool.

Yes, it is that simple. No complicated techniques, no lengthy process to roast some beans to get some coffee. True, it could not rival many of the coffee bean roaster in the market, but then again -spirit of ownership and fun at DIY should make up for the slightly lower level of taste profile...
