Ever wonder what goes into roasting the coffee you drink every morning? We're taking you behind the scenes of our roasting process at Ignite Coffee Company in Oceanside, California.
When you walk into a coffee shop, you probably notice the smell of freshly brewed coffee, the sound of espresso being pulled, and baristas preparing drinks. But there's another side of coffee that most people don't get to experience: roasting.
At Ignite Coffee Company, we roast all of our coffee in-house, right inside our café in downtown Oceanside. From selecting green coffee to carefully developing each roast, there's a lot that happens before those beans ever make it into your cup.
Here's a look at what goes into a typical day of coffee roasting at Ignite.
1. It All Starts With Green Coffee
Before coffee develops that familiar brown color and rich aroma, it starts as a green, unroasted bean.
Coffee is an agricultural product, and just like wine, its characteristics are influenced by where it's grown, the climate, elevation, variety, and how it's processed after harvesting.
For example, our Ethiopian coffee has a completely different flavor profile from our Honduras. Ethiopian coffees often have more floral, fruity, and citrus-forward characteristics, while Honduran coffees can offer more chocolate, caramel, and nutty notes.
One of my favorite things about roasting is discovering how to bring out these natural characteristics rather than covering them up.
2. Preparing the Roaster
At Ignite, we roast on a San Franciscan SF-10 coffee roaster.
Before roasting begins, the machine needs time to warm up. Getting the roaster to a consistent starting temperature is important because it helps create repeatable results from batch to batch.
Once everything is ready, we weigh out our green coffee, check our roasting plan, and prepare for the first batch.
Every coffee responds differently to heat, so the approach we take with our Ethiopia isn't necessarily the same as the one we use for our Honduras.
3. The Roasting Process
This is where things get interesting.
Once the green coffee enters the heated drum, the roasting process begins. Throughout the roast, I'm monitoring several important variables:
-
Bean temperature: How quickly the coffee is heating up.
-
Gas: The amount of heat being applied throughout the roast.
-
Airflow: How air moves through the roasting drum, influencing heat transfer and removing smoke and chaff.
-
Rate of rise: How quickly the bean temperature is increasing over time.
As the coffee heats up, it goes through several stages.
First, the beans begin losing moisture and transition from green to yellow. As roasting continues, chemical reactions develop the aromas, sweetness, and flavors we associate with coffee.
Eventually, we reach one of the most recognizable moments in roasting: first crack.
First crack happens when pressure builds inside the beans, causing them to make a popping sound similar to popcorn.
This is an important milestone because it signals that the coffee has reached a new stage of development.
From here, the decisions we make about heat, airflow, and when to end the roast can dramatically influence the final flavor.
4. Finding the Right Roast Profile
One of the biggest misconceptions about coffee roasting is that darker automatically means stronger or better.
In reality, roasting is about finding the right balance for each coffee.
Personally, I've always gravitated toward lighter roasted coffees. I love how they preserve more of the unique characteristics that come from the coffee's origin.
Our Ethiopia is a great example. When roasted lighter, it can highlight beautiful floral notes, bright acidity, and delicate fruit flavors.
That's why I especially enjoy brewing it as a pour-over or drip coffee.
On the other hand, some coffees benefit from additional roast development, which can bring out deeper sweetness, a fuller body, and familiar flavors like chocolate and caramel.
There's no single perfect roast level for every coffee.
Our goal at Ignite is simple: roast each coffee in a way that highlights what makes it special.
5. Cooling, Resting, and Packaging
Once a roast reaches its desired development, we release the beans into the cooling tray.
Cooling the coffee quickly is important because it helps stop the roasting process and prevents the beans from continuing to develop from residual heat.
After cooling, the coffee is ready to rest.
Freshly roasted coffee releases carbon dioxide over time, a process known as degassing. Giving coffee some time to rest can help improve consistency and extraction when brewing.
From there, we package our coffee for customers purchasing bags online, our wholesale partners, and the drinks we serve inside our café.
Every bag represents a process that started long before the coffee ever reached our roaster.
6. The Challenge of Consistency
One thing that surprised me when I started roasting was just how much attention goes into making coffee taste consistent.
Even when roasting the same coffee, small changes in the surrounding environment, green coffee, and roasting conditions can influence the outcome.
That's why we monitor our roasts, record data, and make adjustments when necessary.
But data only tells part of the story.
Ultimately, the most important test is how the coffee tastes in the cup.
Roasting is a combination of science, experience, and constant learning. It's one of those crafts where there's always something new to discover, no matter how long you've been doing it.
7. Why We Roast Our Own Coffee
For us, roasting in-house is about more than simply producing coffee.
It gives us the opportunity to be involved in another important part of the coffee journey.
We get to experiment with different origins, develop our own roast profiles, and make decisions about the flavors we want to share with our customers.
It also means that when someone walks into our café and asks about a particular coffee, we can explain not only where it came from but also how and why we roasted it that way.
There's something incredibly rewarding about taking a raw agricultural product and transforming it into something people look forward to drinking every morning.
And honestly, that's one of my favorite parts of owning Ignite.
