Roasting in a popper is a DIY venture so you will need to assess your own situation and make accommodations accordingly. Some of the most common issues:

The Air Popper Method

Almost everyone has an air popcorn popper lying around in the kitchen or collecting dust somewhere in the garage. If you dont, you can often find them at thrift stores for under ten bucks.

Thats good because using them in this manner would void your warranty, so if possible, youre going to want to avoid buying new just to try this method out.

Ideally, this is something youll want to do outside, at least for the first time so that you can gauge how much smoke is going to be produced. Its never any fun to have to unplug the smoke detector or swat it off the wall to shut it up in the middle of your roasting experiment!

If doing it outside is inconvenient, then do it in your kitchen, preferably directly under a light so you can get a good view inside the machine, and be sure to open the windows and doors to provide better ventilation. Once those preparatory steps are complete, youre ready to begin.

Roasting Beans In The Oven

  • Arrange the veggie steamer on the cookie sheet, and add your beans until the bottom of the steamer is covered.
  • Preheat your oven to 500 degrees
  • Place the steamer/cookie sheet into the oven and wait.
  • Remain close at hand and listen for the sound of the First Crack The exact time will vary depending on your oven, but it should happen at around the five-minute mark.
  • Check coloration at two-minute intervals thereafter, and as always, remember to pull your beans out of the oven a bit before they reach your desired roasting color.
  • Pour immediately into a waiting colander in the sink and stir gently with a wooden spoon to remove chaff.
  • Let cool for four hours.
  • Store in an airtight container.
  • Again, dont forget to put the battery back in your smoke detector when youre done!

Compared To Roasted Beans Green Or Raw Coffee Beans Last Much Longer When Stored Properly

When stored in a cool, dry place in a sealed container, green coffee beans can last at least a year before losing any noticeable quality.

The trick is to store it at the right temperature and humidity level.

The ideal temperature is approximately 60°F at 60% humidity and no higher than 80°F. Higher humidity levels may lead to mold, while lower levels could cause the beans to dry out.

Dont forget to periodically open the storage container and give the green coffee beans a shake to let air circulate over them.

And remember, it is not necessary to freeze or refrigerate green coffee beans.

Best of all, the longer shelf life of green or raw coffee beans allows you to purchase them in bulk at wholesale prices. As you can see, learning how to roast coffee beans starts with high-quality green coffee beans.

Resting Your Beans For The Best Flavor:

How To Guide for Roasting Coffee at Home

Contrary to popular myth, you generally don’t want to grind and roast the beans immediately. While some coffees like our Brazilian Adrano and our Nicaragua El Recreo seem not to need much rest and can be enjoyed right away, most coffees will be flat, woody, and bitter right after roasting.

Coffee is a polyphasic food, meaning many molecular changes occur after roasting. The beans need to outgas some of the products of combustion to achieve the right flavor balance. Most the time, you can enjoy the coffee the next day, although optimal rest periods can be 1 day, 2 days or even 3 days, depending on the coffee. .

The Spruce / Pete Scherer

Roasting your own coffee is economical, fun, and easy to learn. While this quick-start guide doesn’t cover every detail, it does provide a concise overview of the most important points. Coffee roasting is an art, rooted in the senses. Ultimately, you must pay attention to the sights, sounds, smells, tastes, and tactile sensations of the roasting process so that you can connect them to the results in your cup. Your creative engagement will drive your exploration, and you’ll be sure to have more than a few great cups of coffee along the way. To begin, of course, you need some coffee beans. Start with an Internet search for “buy green coffee.” You will find much to choose from, but don’t agonize. Simply begin at the beginning, and buy one that sounds interesting.

What Is First Crack

During the roasting process, coffee goes through two cracks. The cracks are popping noises that happen as the green coffee beans expand and lose moisture. The moisture creates steam that forces the beans to crack open to release it.

First crack usually happens between 3-5 minutes and the coffee can be done anytime after this point. Light roasts are usually complete soon after first crack, medium roasts are complete sometime between first crack and second crack and dark roasts are complete around or immediately past second crack.

It can be tricky at first to identify first crack and differentiate it from second crack. This will get easier as you become more familiar with the roasting process and what sounds to expect and when.

What Happens When You Roast Coffee Beans

While the technique may seem straightforward, theres more going on during home roasting than meets the eye. Theres a chemical process taking place at the molecular level that transforms more than 800 compounds in the beans from flavorless and raw into aromatic and delicious.

Heres whats happening, according to Giuliano: First, as you heat the beans, the tiny reserves of water they hold evaporates, reducing the mass of the beans by around 11 percent. After about three to five minutes, when the last bit of water escapes, it turns to steam and causes the coffee beans to pop and crack.

A few minutes later, the second pop or crack is the result of carbon dioxide created during the roasting process. The beans will continue to release this carbon dioxide for hours, even days after roasting is complete.

And its all because of heat. Giuliano says, The heat causes a variety of chemical reactions, including pyrolysisa process of temperature-induced decomposition of coffee materialand Maillard reactions wherein sugars and proteins turn deep brown. This is similar to whats happening when foods like steak and toast brown and develop rich flavors.

Every type of coffee has a unique chemical reaction, but Giuliano says a skilled roaster knows how to coax a roast along and, more importantly, when to stop to get exactly the flavors they are looking for. Its a skill that only comes with practice.

Why Roast Your Own Coffee Beans

The reasons are pretty simple here. For starters, its far more fiscally responsible for you to buy your own green coffee beans. They are usually less expensive than roasted coffee beans.

Some types of roasted coffee beans can be as much as $20 per pound, but raw green coffee beans can be as little as $5 per pound. Not only that, but you can also create your own flavor profile.

Since you bought your own, you can combine ingredients together and create the best coffee profiles and aromas that you love.

One common misconception is that light roasts have more caffeine than dark roasts. The caffeine levels are actually pretty similar. Lighter roasts generally are more acidic. Medium roasts have less acidity and a better flavor profile, while dark roasts have the richest flavor profile.

Roasting coffee beans involves a chemical reaction called the Maillard reaction. This occurs between amino acids and reducing sugars under high heat, which browns the beans. This brings about new aromas and flavors in the beans. The same thing happens when cooking a steak or browning butter for a cake.

Tips For Roasting Your Own Coffee

To get you on the right track immediately, the pros have a few suggestions. First, set up your workstation outdoors, if possible. Roasting creates a significant amount of smoke and an aroma similar to burnt popcorn, so do it outside or in a well-ventilated area.

And keep in mind that timing is as much an issue after roasting as during. It may be tempting to grind your beans right away, but that wont yield the best flavor. So wait at least 24 hours before using your beans to make a cup.

Likewise, dont put the beans away as soon as they are cool. As we said, they will continue to release CO2 as they rest, and the excess gas can cause the lid of your storage container to pop off. Instead, wait 12 hours before packing them up. This also helps ensure theres neither too much CO2 nor too little in the final product.

When your beans are ready to grind, use them within a week or two for the best flavor. And if at first you dont succeed, try again. Experiment. Thats what lifes all about, Wilson says. Once you get it fine-tuned, roasting your own coffee is very rewarding.

How To Roast Your Own Coffee At Home

Can You Roast Coffee at Home?
  • Find a place to roast the coffee.

    You dont need a lot of space, but it will get a bit loud, will smell and potentially smoke a bit.

  • Measure out the green coffee beans.

    You can roast as much or as little coffee as youd like, but Ive found 60-75 grams is the sweet spot for these smaller popcorn poppers. If you try to roast too many beans, it gets harder for the air from the popcorn popper to circulate the beans and get an even roast.

  • Begin roasting the coffee.

    Pour the green beans into the popcorn popper and turn it on. The entire roast process will take 4-10 minutes from beginning to end. As the coffee begins to roast, I like to gently shake the popcorn popper to help the beans circulate more evenly. As the beans roast they become less dense, so the circulation happens without any intervention.Remember: the popcorn popper will get very hot during the roasting process, so be sure to use some sort of protective equipment if it starts to get too hot.

  • Listen for the first crack.

    As the coffee begins to roast and darken in color, listen carefully for cracking noises. It will sound similar to popcorn popping and should happen around 3-5 minutes into the roast. You can choose to complete your roasting anytime after first crack. Keep a close eye on the beans through the popper to see their color and find the roast level that matches your preferences best.

  • Dump out the beans.

    At Home Roasting Methods

    How to Roast Coffee Beans At Home (Stove Top Method)

    So there are 4 different types of coffee roasting that can be done at home, all with their own pros and cons, lets have a brief overview.

    • Pan Roasting Coffee Beans
    • Roasting in a Popcorn Popper
    • Roasting in a Home Coffee Roaster

    They are pretty self-explanatory. Pan roasting is roasting in a pan, usually a cast iron skillet. Oven roasting is roasting beans in the oven, and so on. While all of these are valid roasting methods, the one Ill show you today is how to roast coffee beans in a pan, which is my favorite method besides using an actual coffee roaster.

    So whats wrong with the other options? Well, oven roasting coffee beans produces far too much smoke for me. While pan roasting produces smoke as well, if your room is well ventilated you should be fine. But when you roast beans in the oven, that smoke builds up and can be overpowering when you try to take them out.

    The popcorn machine method, which I see often on the web, is a joke in my opinion. While you can get success with this method, I think its just too dangerous and not cost effective. There is too much chance of starting a fire, as well as the fact that eventually you will break your popcorn machine after a couple of months of roasting.

    But surely the best method is using a purpose built coffee roaster, right? Right! However, theyre either so damn expensive, or ridiculously difficult to use.

    So, unfortunately, there is no cheap and easy method. Well other than buying beans that have already been roasted.
