Equipment for Home Roasting

Roasting your coffee beans at home requires only a few basic pieces of equipment. The following items are required to prepare coffee beans for roasting:

A roasting/cast iron pan

Most of us do not have coffee roasters at home, right? So, if you have an expensive roaster, go for it and roast fresh coffee beans. Otherwise for home roasting, you will simply need a roasting pan or a cast iron pan so that you can roast coffee beans in the oven. Even if you don’t have either of them, it is easy to buy one and you can certainly use it for something else other than roasting coffee beans.


If you have a coffee grinder, then that is a great investment to own. The grinder is a very important and useful tool for making coffee at home. By grinding the coffee beans, the rough surface of the bean is exposed to heat. By using the grinder and roasting beans in the oven, you will get a much darker, richer taste. This can make your home roasting easy and efficient. It takes some patience, but roasting coffee beans in the oven is really a good method to do so. You will be able to roast up to 2.5 lbs of coffee beans on a single-use.

Heatproof spatula

You need to hold the grinder at a steady level with the help of a heatproof spatula. The grinder should only be in contact with the ground pad so that it does not spill or slip. Keep the heatproof spatula close to the grinder.

Roasting coffee beans at home is a great way to taste the real coffee flavour and determine the quality of green beans. It can be done in one or two batches depending on the number of beans you want to roast. Remember to roast coffee beans in a well-ventilated area.

Here’s a step-by-step guide on how to roast coffee beans at home:

  1. Preheat your oven to 450°F.
  2. Pick out your coffee beans, wash them off in the sink and rinse thoroughly.
  3. Put the coffee beans into a small roasting pan with a lid.
  4. Place the pan inside the preheated oven and bake for 25-35 minutes. Rotate the coffee beans from the bottom to the top occasionally throughout the roasting process.
  5. Remove the roasting pan from the oven and open the lid. Check for good quality beans by opening them up and smelling the beans. If your coffee beans smell nice, they are ready to be ground and brewed. Allow the coffee beans to cool down.
  6. Sprinkle the coffee beans with coarse salt and place them in a sealed container for approximately 2 weeks.

Can you use a popcorn popper to roast coffee beans?

The good news is that you can roast coffee beans in a popcorn popper! The bad news is that you can’t do it as efficiently as other roasters. The reason for this is the popcorn popper does not heat up the beans evenly. This makes the process take longer and beans will end up with a more uneven roast. The other problem is that the popcorn popper doesn’t produce much pressure. This means that the coffee beans stop roasting before they are done and for the same reason, this roasting process takes longer. Still, this is an option for those who want to try something new but want to stick with old technology. In fact, I tried this method a long time ago and it sort of worked although the coffee didn’t taste as good as the one from coffee roasters. Roasting coffee beans can make a mess, so I recommend doing it either outside or in the bathroom.

Here is a guide to how to roast coffee beans in a popcorn popper:

  1. Start by pouring 1/2 cup of raw, green coffee beans into the popcorn popper.
  2. Set the popcorn popper on high heat.
  3. Now, it’s time to wait for it to finish popping – that should take about 12 minutes.
  4. Once that’s done, it’s time to smell the aroma of roasted coffee beans.

What Kind of Green Coffee Bean Should I Buy?

When it comes to selecting green coffee beans, the first thing that comes to your mind would be the country of origin. The type of green coffee bean would depend on the country where it was produced.

Coffee beans from Brazil are a popular choice, but are very delicate and can’t be sold abroad. Green coffee beans from Vietnam are more common in the market, as Vietnam is a member of the International Coffee Organization. Vietnam has the best quality green beans but often produces lower-quality beans.

How to Store and Use Roasted Beans

Store coffee beans in an air-tight container with a tight lid. Coffee beans should be kept away from light, heat and moisture to ensure optimum roasting and preservation of flavour. If you’re concerned about storage conditions, you could store coffee beans in the refrigerator.

Roasted coffee beans can be used in many recipes, including traditional breakfast drinks like lattes and cappuccinos as well as for drinks like smoothies and energy-boosting cocktails.
