Light, medium or dark roast? Learn what's behind coffee roasting and how it can help you to choose the coffee beans with the right roast for your palate.
- 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.
- 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.
- Light Roast Coffee: pronounced acidity, clear and mild cup, more origin flavors.
- Medium Roast Coffee: balance between acidity, sweetness and aromas.
- Medium-Dark Roast Coffee: lower acidity, more chocalate-like notes, heavier mouthfeel.
- Dark Roast Coffee: notes of dark chocolate, heavy mouthfeel.
- This is only a guideline as coffee flavors depend also on roast profiles, varieties and processes.
