How Would The Roasting Time Of Coffee Beans Affect Their Caffeine Content

As much as coffee is a favorite with many people worldwide, many myths surround caffeine’s intensity depending on roast types. The types of coffee roasts are light, medium, and dark. Some people assume that the stronger the taste of the coffee is, the more caffeine it contains. For this reason, those that like their coffee bitter prefer dark roasts to light roasts and assume that the longer roasting time brings out more caffeine content from the coffee beans.

Others think that light roast contains more caffeine because the shorter roasting time does not burn off the caffeine. In this article, we set to debunk any myths concerning roasting time and its effects caffeine content in your coffee drink.

Factors that affect caffeine content in coffee

Coffee gets its caffeine content from the beans, and besides the roasting time, other factors affect its levels. The factors that affect caffeine levels include the type of coffee beans, type of roast, brewing method, and coffee type.

Coffee beans

The caffeine content in your cup depends on whether you are drinking Arabica or Robusta coffee beans. Arabica and Robusta are the most popular type of coffee beans, and they come with different caffeine levels. The majority of the elite coffee houses worldwide use Arabica beans because they are better in quality compared to Robusta beans.

Even though Robusta beans have lower quality than Arabica, they contain more caffeine levels. Brewing and roasting methods are the only possible processes that alter both coffee beans’ caffeine levels.

Type of roast

The most popular types of coffee roasts are dark and light roast coffee. Dark roast has a bolder and deeper flavor than a light roast, but it does not mean that it contains more caffeine than the light roast does. Both dark and light roasts include the same levels of caffeine though some say that light roasts have more caffeine because they go through a short roasting time, which helps preserve the bean’s caffeine content. Caffeine levels depend on the number of beans that you use during the roasting process. If you have the same scoop of both dark and light roasts, you should have the same caffeine content.

Brewing method

If you use coffee brewing methods with higher extraction levels, you will have coffee with more caffeine content. Besides the brewing method, other factors that affect caffeine content during the process include water temperature and grind size.

Instant or brewed coffee

If you chose to drink instant instead of brewed coffee, then you will have less caffeine content in your coffee cup. The average caffeine content in an instant coffee cup is 65 mg, while brewed coffee contains an average of 115 mg per cup.

Conclusion

Now you know that roasting time only changes the taste and flavor of the coffee and the mass density without changing the caffeine content. Caffeine levels only vary depending on the number of coffee beans you use on your coffee cup or the other factors listed above.

PRESS RELEASE: SUPPORT FOR BENOÎT BITEAU

Benoît BITEAU, an organic farmer who reduces irrigation, changes practices, preserves the quality of soil, water, air and biodiversity, is given a double penalty because the management of an organic farm is already a significant investment.

For many years, associations for the protection of nature and the environment have denounced the financial provisions provided for in the common agricultural policy which subsidizes farmers who have bad practices, disastrous for health and the environment, so that they do “less worse”. The heavily subsidized alibis measures have no effect.

It is unnecessary to recall the damage caused by chemical intensive cereal agriculture. For decades, ever more alarming reports have been piling up in government departments – everything and its opposite.

Two examples suffice:

  • Nitrates: 5 successive action programs, 20 years of palaver, a risk of condemnation of Europe and in 2014 a situation which is further deteriorating despite the billions of euros spent in vain.
  • Pesticides: after the displays of the Grenelle de l’Environnement, the good intentions of the 2018 ecophyto plan, in recent years, the quantities of chemicals used in agriculture have increased.
THE PAID POLLUTER

For water, the situation is just as incomprehensible. The aid goes mainly to those who practice polluting agriculture.

Let us take the example of a cereal farmer, corn grower who irrigates 160 ha including 115 ha of grain maize, he will ask for 1 million euros of public money to build a water reserve and he will obtain them.

While this farmer cultivates corn which consumes 2,500 m3 of water per ha which requires the use of chemicals and nitrates which are leached and end up in rivers and the sea because the land remains bare all winter, the French agricultural policy will encourage it to continue and perhaps even to intensify its practices and production.

With such inconsistencies, aid to maintain failing meadows, agriculture geared towards the production of cereals for export, tens of thousands of hectares of meadows have already been plowed with all the consequences that we know in particular. on wet areas.

Hopefully our rulers will get their act together and put some order in the distribution of public money.

PARTICIPATORY SURVEY ALYTE MIDWIFE: DID YOU HEAR IT?

The Alyte accoucheur is currently the subject of a regional investigation in Poitou-Charentes. This is based on participatory inventories in the 4 departments during the species’ reproduction period (April to June). In Charente-Maritime, Nature Environnement 17 will coordinate these inventories with the technical participation of the League for the Protection of Birds.

In order to present the methods of these inventories to you (methodology, number of passages, sites selected, etc.), we are already offering 2 training courses on sectors where the species is present:

  • March 21: L’Alyte midwife in Mirambeau

Philippe Delaporte and Olivier Roques

After an indoor presentation of the participatory survey project, come and discover an original population of Alyte in the town of Mirambeau.

Meeting at 6.15 p.m. in the parking lot of the Petit Niort cemetery (Mirambeau, direction of Bordeaux)

Bring walking shoes and flashlight.

  • April 7: A whistling toad in Saintes: the midwife Alyte

Jean-Claude Martin and Olivier Roques

In the heart of the city of Saintes, come and listen to and discover the habitat and ecology of this little toad.
