Troubleshooting Roasting Problems

So you’re a coffee roaster, huh? Congratulations. You’ve taken the first step on the road to become an expert in all things coffee-related. Roasting your own beans has been described as “chef’s cooking” for coffee drinkers, and it does feel like a big accomplishment when you successfully turn out a cup that’s delicious and perfectly roasted. But what happens when things go wrong? Troubleshooting roasting problems—and learning from them? We’ll walk through some common scenarios where your roasts might not be turning out quite right and how to fix them:

Your coffee tastes sour.

If your coffee tastes sour, it’s most likely due to one of these issues:

  • Too much moisture in the bean. This can be caused by roasting at too high a temperature or for too long a time.
  • Excessive oxygen exposure during the roast process can also cause your beans to taste sour and bitter, so make sure you’re using protective equipment like an airtight lid or roaster hood when firing up those flames! If you don’t have any protection, consider taking some precautions by covering them with foil while they’re heating up (and keep an eye on them so they don’t burn). You should also avoid opening windows while roasting; this will let more oxygen into your space and prevent proper airflow around each batch of beans as they cool down post-roast

Your coffee tastes burnt, or has too much char.

If your coffee tastes burnt, or has too much char, it’s probably because you’re roasting too long.

The best way to avoid this problem is by keeping an eye on your beans during the roasting process. If they start to turn black or develop a lot of char, stop immediately and let them cool down before trying again.

Your coffee tastes weak and bland.

If your coffee tastes weak and bland, then it’s likely that you’ve under-extracted it. This can happen when the roast level is too light or you’re using a bean with a high water content (such as a washed Ethiopian). If this is the case, try increasing your roast level by one step or using a darker-roasted bean with less moisture content.

Roasted coffee is bitter.

A. Use a more gentle roast. A longer roast will allow the coffee to develop more of its flavor and aroma, but it may also make the coffee taste bitter if you’re not careful.

B. Use a lighter roast. If your beans are already dark brown or black, there isn’t much more to be gained by roasting them any further–and you’ll probably end up with a burnt taste instead!

C. Use a darker roast (or overroast). If your beans aren’t dark enough yet, aim for medium brown rather than light brown when you go into second crack; this will yield better results than trying to get extra dark without getting into third crack first!

D.. Increase temperature during second crack; decrease temperature after first crack ends

Roasted coffee is flat.

There are a number of reasons your coffee may be flat. The first step is to make sure that you’re using fresh beans and grinding them just before brewing, as stale or over-roasted coffee will result in a weaker cup of joe. If that doesn’t work, try under-roasting the beans (or roasting them for less time) to bring out more of their natural sweetness.
