Blends are one of the most undefined and unrefined practices in the coffee world today. I would argue that a coffee company often spends a good amount of time fine-tuning their espresso blend, and then leaves the rest to chance.
Have a coffee that is turning old? Throw it in a blend. Have a coffee that didn’t sell well? Throw it in a blend. Need a cheap coffee to spread out the cost of an expensive lot? Throw it in a blend. Arguably, I’ve seen many coffee blends in the past that have performed one or many of these functions: pair a decent coffee with a not so decent one, and you have the lesser of two evils that still tastes pretty good. In this era of single origin and crazy processing styles (carbonic maceration, what is that?!) I think we under-appreciate the complexity offered from a well thought-out blend of coffee.
Taking a step back, I like to draw inspiration from the wine industry. When I search for a bottle of wine, I’m enamored with single varietals—grapes that I’ve never tasted before to expand my palate. Some are floral. Some are heavy-bodied. None are terribly balanced. They’re great for one or two applications, or for sipping at a tasting, but they’re often not dynamic nor complex in flavor and overall profile.
Enter: blends. Some of the most prestigious wines in the world (Burgundy, Bordeaux, California Reds) are all blends of a variety of grapes. Each by themselves is delicious, but in layering several together, you get a complexity that is not possible by itself.
The whole of a blend should be greater than its parts.
That was the inspiration behind this year’s Sun Summer Blend. We wanted to use coffees that would be delicious enough to serve as a single source coffee, yet becomes something more unique and special when blended together. Even before we knew which specific coffees we wanted to feature, we knew our game plan. We wanted to recreate the sensation of an “Arnold Palmer in coffee format.” We quickly thought of two regions of coffees that strongly exemplified these characteristics: the Yirgacheffe region of Ethiopia and the Huehuetenango region of Guatemala.
What we ended up choosing was a rad combo of coffee. First, let’s introduce you to the two players in this blend.
Ethiopia Yirgacheffe Reko: This was, by far, our favorite Ethiopia Yirgacheffe we’ve cupped this year. Reko comes from a washing station of the same name, found in the Kochere region of Ethiopia. Reko translates to “challenge,” as this hill is steep and treacherous. That said, the coffee brought here by 850+ small coffee farmers have a phenomenal profile year after year. Their meticulous attention to detail and ability to educate their producer partners sets this coffee apart. In processing, it’s floated, separated by stages of harvest, and meticulously watched every step of the way. This coffee is a floral bomb, with notes of black tea, jasmine, and citrus.

Guatemala COMYPE S A: We found this one off a blind sample table of Guatemalan coffees from our friends at San Miguel Coffees. The brightness and cleanliness of this cup, along with its crisp acidity, made us want to learn more. When we revealed the lot, we learned it was from a small cooperative in Huehuetenango called COMYPE. This group is composed of small producers, 70% which are women owned. This lot features a washed coffee that is a blend of Pache, Caturra, Catuai, Bourbon, and Typica varieties. The terroir and variety give this coffee an extremely punchy acidity, along with strong notes of citrus and brown sugar.

So, when you put these two together, you get some magical sparks. Again, the goal was to create a blend that was reminiscent of an Arnold Palmer. In our Sun Blend, you’ll get a dynamic mouthfeel created by both coffees playing off of each other. You’ll get the black tea and jasmine texture of the along with the sweet juiciness of the COMYPE. The acidities layer nicely to give you the feeling of a bright squeeze of citrus fruit. The finish of both coffees, layered together, is sweet and floral.
We get this question a lot: Do light roasts have more caffeine than dark roasts?
There’s so much misinformation out there, folks are never quite sure what’s true and what’s not. In fact, I often hear people order light roast coffee because they believe it’ll promise more of that boost. But are they right about that?
Let’s look at the science of roasting and see if this checks out—or if it’s just an urban coffee myth.
During the roasting process, we take raw (green) coffee from room temperature and modulate the flavor and profiles of the bean over 9–14 minutes. We typically crank up the temperature hotter than 400 degrees Fahrenheit while we’re at it.

The beans’ color changes quite a bit, from green to yellow to light brown to deep brown to black. The flavors also change via maillard and Strecker reactions (really cool and complex non-enzymatic reactions that I won’t spend much time on here, but if you want to learn more, I suggest checking this TED video about chocolate chip cookieschange at different temperatures.) One thing we fail to look at (or adequately explain) is what happens to the caffeine inside of the coffee bean.
Do you know why coffee has caffeine? It’s a feature that was naturally selected over the years. We obviously know that caffeine is a stimulant. The plant uses this to defend itself from many different pests. The caffeine overstimulates the bugs, paralyzing them, and preventing them from further damaging the plant (pretty ‘effin cool defense mechanism, if you ask me!).
So, we know that caffeine is a naturally occurring stimulant. We also know that caffeine does not begin to degrade until around 455 degrees Fahrenheit (e.g., it’s stable and not breaking apart). For example, Mission Coffee’s darkest roasts are lucky to get up to 430 degrees Fahrenheit. Logic would tell us that the bean often does not get up to a high enough temperature to cause the caffeine to degrade. So, if you had a light roast bean and a dark roasted bean of the same coffee, per volume, it would likely have a comparable amount of caffeine, right?

Caffeine content is actually correlated to coffee varieties (each plant will have a slightly different level of the chemical). Most coffees, whether they’re light or dark roasts, actually have the same amount of caffeine.
So, what is actually dissolvable in a coffee? And does it change from a light roast to a dark roast?
Well, does burnt toast taste different than perfectly golden toast? (Yes). Can you get the same nutritional value from each? (Maybe? I’m not a scientist.) It seems likely and logical that dark roasts are slightly less soluble (there’s much less stuff to dissolve; less flavors, things have degraded and changed, etc.). But, one thing that doesn’t change at these roast levels is caffeine.
While a light roast bean and dark roast bean may have the same amount of caffeine, when you look at the finished brew, there may be negligible smidgen more caffeine in a dark roast simply because there’s less of other stuff in there.
If you want to get even deeper into this topic, I recommend checking out this article on Daily Coffee News. You’ll have all the roast-related details you need.
Turns out, there’s no real difference if you’re drinking a dark roast or light roast. You’re likely to get a nice dose of caffeine from both. But, if you want to have a drink with slightly less caffeine, look for coffee beverages with a lower CONCENTRATION of coffee to water. (There’s a lot more coffee per ounce in espresso than cold brew; more in cold brew than drip).
Next time you’re standing in line at Mission Coffee Co., know that, light or dark roast, you’ll get that much-needed caffeine boost either way!
