Coffee Roasting


In short...

  • Typical roasting temperatures used for specialty coffees do not affect caffeine content.
  • The physical changes of the coffee bean (volume and weight) define the concentration of caffeine in the bean.
  • Caffeine content also depends on the variety, the species and the brewing technique.

In short...

  • Physically, coffee beans do not expire and thus it can have an extended shelf life, especially if stored appropiately.
  • However, the intensity of coffee flavors decline with the time.
  • To get a good brew, coffee needs to rest for a couple of days so that coffee flavor compounds can be properly extracted.
  • The rest time of coffee after roasting can be as long as 4 to 12 days. It is not recommended to prepare coffee directly after it had been roasted.
  • Knowing the roasting date allows you to assess the days it need to rest to get a better extraction.
