Blends are essential offerings on nearly every coffee shop menu, making it crucial for roasters to master the art of blending. However, the process of creating coffee blends comes with its own set of challenges, including selecting the right coffees and roasting beans from diverse origins, varieties, and densities.
To gain insights into crafting high-quality blends, I had the opportunity to speak with Jen Apodaca, the Director of Roasting at The Crown: Royal Coffee Lab & Tasting Room. This innovative educational facility and event space is set to open in Oakland, California. Join me as I share the valuable lessons learned about creating coffee blends that consistently delight the palate.
Why Consider Blending?
Blending often carries a negative stigma; many believe that roasters resort to it merely to use up leftover or past-crop coffees, masking undesirable flavors with other profiles. Jen clarifies, “While this can happen, the primary reason most roasters create blends is to satisfy consumer demand for a flavor profile that is both repeatable and consistent throughout the year.”
In essence, creating coffee blends allows roasters to cater to specific consumer preferences. Developing a signature blend can also help define your brand and encourage repeat business, as customers return for a familiar favorite. While single-origin coffees maintain their appeal, they offer a seasonal and unique experience that lacks the constant availability consumers often seek. This is why many third-wave coffee shops feature both single origins and blends.
Additionally, blending can enhance the product itself. “The most apparent benefit,” Jen notes, “is the ability to craft a more dynamic flavor profile than a single coffee can provide.” The golden rule of creating coffee blends is that the combination should yield a flavor experience superior to that of the individual coffees. Often, blending results in a balance and complexity that showcases the best characteristics of each component coffee.
Navigating the Challenges of Creating Coffee Blends
Balancing various coffees for flavor and roast profile can be quite challenging. Jen explains that mastering the art of creating coffee blends requires extensive practice to determine which coffees work well together, the ideal percentages for each, and the appropriate roast levels.
Even after achieving a harmonious and unique blend, your journey isn’t over. There may be times when you need to substitute one of the component coffees, whether due to running out or changes in roasting characteristics over time. “This can happen to anyone,” Jen emphasizes, highlighting the importance of careful purchasing decisions to mitigate this issue.
Don’t expect to perfect your blending skills overnight. However, with each attempt, you’ll gain a deeper understanding of what combinations succeed, ultimately pushing you to improve as a roaster.
How Many Coffees Should You Include in Your Blend?
Jen suggests limiting your blend to no more than five different coffees, with each component making up at least 8% of the final mix. “When you prepare an espresso, you typically grind about 17 grams of coffee, which translates to just over a hundred beans,” she notes. “If a blend component comprises only 5% or 3%, it feels like a missed opportunity.”
After all, would a 3% component truly make it into every espresso shot?
That said, there are no hard and fast rules. Jen acknowledges that certain coffees might be brewed in larger batches—say, 200 grams—making smaller components more viable. It’s crucial to consider the purpose of the blend and how it will be served.
As for determining the optimal blend ratios, that will depend on the specific coffees you choose to combine.
Choosing the Right Component Coffees for Creating Blends
When crafting a coffee blend, especially a signature one, it’s essential for your final product to have a distinct character while also achieving balance. To help you in this process, Jen offers some valuable tips:
1. A Sweet Base Note: Start with a coffee that develops browning flavors well, such as those from Brazil, Mexico, or Peru. These coffees provide a solid foundation for your blend.
2. Mid-Palate Satisfaction: This phase occurs between the initial sip and the swallow, representing the core of the coffee-drinking experience. To avoid a “hollow” flavor, look for juicy coffees rich in malic acid, with flavor notes reminiscent of green apples, peaches, or stone fruits. Consider origins like Costa Rica, Colombia, Guatemala, and Burundi for this component.
3. High Notes: For brightness and floral undertones, include coffees that can be roasted lightly. Kenyan or Ethiopian beans are excellent choices for achieving citric acidity and floral aromas.
Interestingly, you don’t need to use wildly diverse origins to incorporate these three elements. Jen suggests that blending coffees from the same origin or even different processing methods from the same farm can yield a great product. “I encourage experimentation,” she says, emphasizing the value of trying new and exciting combinations.
Determining Your Blend Ratios
Let’s say you’re working with a three-coffee blend based on the elements mentioned above. Jen recommends starting with a ratio of 40% sweet base note, 40% mid-palate, and 20% high notes. From there, Creating Coffee Blends you can gradually adjust the ratios until you achieve your desired flavor profile.
While experimenting with different ratios, some coffee will inevitably go to waste. To minimize this, Jen roasts the component coffees in small batches separately, then brews and combines them in various proportions, such as 40:40:20, 30:30:40, and even 60:20:20.
Additionally, it’s crucial to taste the coffee as it will be served in the café. “You can do extensive testing,” she explains, “but if the espresso shot doesn’t reflect the flavor profile you aimed to create, you’ll need to start from scratch.”
Pre-Blending vs. Post-Blending: Which Approach to Creating Coffee Blends Is Right for You?
After selecting your component coffees and determining the blend ratio, a crucial decision arises: should you blend before or after roasting? Let’s explore the advantages and disadvantages of each method.
Post-Blending: This method involves roasting each coffee component separately and then combining them afterward. Many small roasters utilize their cooling trays or cement mixers for this purpose.
Pros: This approach allows you to roast each coffee exactly as desired, leading to superior results. It enables precise control over the roasting process, creating coffee blends ensuring that each component reaches its optimal flavor profile.
Cons: However, consistency in batch size can become a significant challenge. Jen notes, “Today you might need to roast 10 pounds of your high note, but tomorrow it could be 25 pounds, and the next day only 3 pounds.” Achieving the same roast profile across varying batch sizes requires skill and experience, making it more complex to maintain uniformity.
Ultimately, when creating coffee blends, the choice between pre-blending and post-blending will depend on your roasting style and specific goals.
Pre-Blending: Understanding Its Role in Creating Coffee Blends
Pre-Blending involves mixing all the green coffee components together before roasting them as a single batch.
Pros: One of the primary advantages of this method is greater consistency in batch size, which simplifies maintaining uniformity during the Creating Coffee Blends roasting process. You won’t need to adjust your roasting profile for different batch sizes. As Jen points out, “Consistency is crucial for quality control.”
Cons: On the flip side, you may encounter challenges with varying screen sizes, moisture levels, and densities among the beans. “These factors can significantly impact the flavor,” Jen warns. “Some beans might end up over-roasted while others could be under-roasted if they’re all roasted together.”
As a roaster, it’s essential to evaluate which approach best suits your business and coffee offerings. “By paying attention, cupping your coffees, and keeping detailed notes, you can achieve great results with either method,” Jen emphasizes. “It’s doable, but it requires effort.”
You can also combine both methods, especially if certain components share similar densities while others do not. For instance, Jen often pre-blends two components and post-blends a third, achieving excellent outcomes.
Creating coffee blends presents both challenges and opportunities for roasters. Not only does it encourage the enhancement of your roasting skills, but it also allows you to develop a signature coffee that can define your brand and attract customers year-round. Mastering the art of creating coffee blends will require time, practice, and a bit of creativity, but the rewards are well worth the effort.
