Freshly roasted coffee beans spread an intense scent. You won't find it in any open coffee packaging from the supermarket. And what smells so good must also be the purest highlight for our taste buds when brewed. This is how you become your own roast master.

When roasting coffee, a wonderful scent is created

The secret of success: experience

Roasted coffee beans develop more than a thousand aroma compounds during roasting, which combine to produce the typical coffee taste. A master roaster controls this aroma formation with his knowledge and experience. At home, nobody can score with such a wealth of experience, but creating your own coffee variants “accidentally” remains exciting. And as long as the cup tastes good, everything is fine.

An infrared thermometer is indispensable

The temperature plays the main flavor role in coffee roasting. It should be in the range of 180 to 230 degrees Celsius. During the approximately ten-minute roasting time, it should also be kept constant. An infrared thermometer is a helpful tool and should not be missing when roasting at home.

This is how you can roast raw coffee beans

  • in a pan
  • in the oven
  • with a heat gun in a heatproof bowl
  • in a special coffee roaster

tips

Incidentally, you can get raw coffee beans in online shops or well-stocked supermarkets and coffee shops.

Roast the coffee beans in the pan

  • 200 degrees Celsius are required
  • Use the thermometer to keep the temperature constant
  • Stir coffee beans constantly
  • The roasting process ends when the beans are dark brown

Roasting in an open pan can be a bit dangerous if individual beans burst. Wearing safety glasses is not a bad idea.

tips

Do not judge the roasting success too early. The development of the aromas continues even after the end of the roasting process and only reaches its optimum after about 24 hours.

Roast green coffee in the oven

  • Wash beans before putting them in the oven
  • Preheat the oven to 200 degrees
  • Recirculation function is recommended
  • Spread the coffee beans out thinly on a baking sheet
  • Roast in the oven for 10 to 20 minutes

tips

Do not open the oven door during the roasting process, and do not stir! This would cause the temperature to drop too much.

Heat gun as a roasting tool

Small amounts of beans can be roasted with a heat gun. As a container for the beans, you absolutely need a heat-resistant bowl. Your eyes must be protected with safety goggles from so-called silver skins flying around.

  • Place the beans in the ovenproof bowl
  • Bread maker also works well as a container
  • find out the correct distance of the pistol by trial and error
  • if it is too small, the beans are only “baked”
  • if it is too close, the aroma will be destroyed
  • Roast for about 12 to 15 minutes

tips

If you have a popcorn machine at home, you can try roasting in it - without the heat gun.

Roasting machines for private coffee

A home roaster can already be bought for 200 euros, but there are also much more expensive ones. But the devices can also offer some useful functions:

  • several adjustable degrees of roasting
  • for all imaginable coffee specialities
  • Roasting up to 300 grams of green coffee
  • Roasting runs automatically
  • Devices are easy to clean
  • no risk of injury from flying bean parts

durability

Freshly roasted coffee is not intended for storage, as it would constantly lose its aroma. It is better to roast smaller amounts of beans at once. If it has to be stored, please do so only after it has cooled down. Hermetically sealed, dark and cool. Use up as soon as possible.
