The growing popularity of gourmet coffee has sparked an interest in reviving the traditions of coffee roasting at home, a daily custom until a century ago.

Toasting homemade coffee does not have to be complicated or costly. There are many ways to roast coffee, from machines made specifically for this purpose to a simple frying pan. Most methods are simple and the results can be excellent .

Once you have chosen the right method for one you need to choose a few grains of green coffee, and learn a little about what to watch for while you are toasting.

Getting a quality green coffee means being halfway to a great cup of coffee ....

GUIDE TO COOKING CAFE

The first thing to do is choose a coffee and a method of toasting

The photo toaster on the left uses an oscillating current, outside the axis of rotation of the drum to agitate the beans and toast them evenly, and a closed flow of hot air to heat the drum.

TASTING STAGES

The most important consideration when roasting coffee is knowing when to stop roasting . Different coffees may require different exposure time.

Each roast highlights or dull certain grain attributes. With a dark roast it is easier not to make a mistake. A light brown roast highlights the notes of coffee and is increasingly used for specialty coffees . You can always experiment and it will be your pleasure to decide the appropriate point in each case.

The stages that cross the grain during the roasting are the following:

After a few minutes the grains turn to a yellowish tone and emit the smell of grass. The grains begin to release steam as their inner water content dissipates. The steam becomes fragrant and then a click is heard, an audible sound " the first creak " and cracks in the grain. The sugars begin to caramelize, the water escapes, the structure of the grain is broken and the oils begin to

For greater precision it is advisable to take into account the temperature of the grains. A kitchen thermometer can be used to measure the temperature of the beans while toasting. If a toaster machine is used, this method is not necessary. Grains should be heated to temperatures of 190 to 280 degrees, but rapid air currents may allow for lower temperatures.

The type and weight of the beans and the cooking temperature can also influence the exposure or roasting time. The registration of this information for each type of green coffee that we go toasting will be especially useful in the future.

Coffee roasted roast – cooling As soon as a batch of roasted coffee is made it should be quickly cooled !!! The roasted coffee bean retains residual internal heat after the heat source is removed which can lead to continue toasting and subtract flavor to the final product. To accelerate the cooling process a colander, ventilation, cooling, etc. can be used

When toasting a thin film is separated from the grain, especially depending on the process of the coffee in origin will have more or less husk. There are several ways to collect and contain that skin. It is important to remove the film and pick it up but if a little gets mixed with the grains is not a problem as it has no
