If you absolutely love coffee, your day probably can’t start without a delicious cup of your favorite roast! But do you know all the factors that affect the taste of your coffee? If you are curious what makes your morning cup extra delicious, we're going to walk you through the science behind the magic!
It all starts with the quality of water!
Most coffee fanatics will know that grind, temperature of the water, roast profile, brew time, and pressure all play a big role in the quality of taste from your cup of coffee. But did you know that the composition of the water you use is also critically important to ensuring that the right flavors are extracted from the beans when brewing? Coffee beans have hundreds of different chemicals in them which can vary depending on the type of bean, where it is grown, and how well executed the roast is. Making sure that your water composition is the highest quality will help in extracting the right flavors from the beans when brewing!
The type of water that you really want to avoid is hard water, or water with salt elements. For the best brewing results, you will want to utilize a filtration system that helps reasonably eliminate the hardness of the water and find a consistency that works best for your palate and the type of roast that you are brewing. It is important to note that no one type of water will consistently reproduce the same flavorful extraction for all roasted coffee. If you are going to begin this journey, we recommend trying different filtration methods until you find the one that works best for you!
Most of what we taste in coffee is actually the smell!
If you were not able to smell your cup of coffee in the morning, the only tastes you would get would be sour and bitter. The delicious and satisfying taste of coffee comes almost entirely from the compounds that are produced when the coffee beans are roasted. There are around 800 different compounds produced during the thermal degradation process when the beans start to heat up. This process of the compounds decomposing proteins and sugars is what gives coffee that unique and tantalizing smell.
If you were to use unroasted or “green” coffee beans to make your morning coffee, it would have an almost grassy like taste. While the same compounds in roasted coffee are present and the level of caffeine is still there (higher, actually!), they lack the same desired aroma because there are fewer volatile compounds that are only released during roasting (oils are key)! It is therefore safe to conclude that the smell that you positively identify as “coffee” is a combination of hundreds of different smells given off by volatile compounds. Isn’t science fun?!
What it takes to make the perfect morning cup of coffee!
Now that we have a better understanding of what gives coffee its unique flavor and aroma, what can we do to generate the best results in terms of flavors? There are five important variables that you can control to brew the perfect cup of coffee:
The quality of the water
The coarseness of the grind
The temperature of the extraction
The duration of the extraction
The coffee to water ratio
If you keep these 5 major variables in mind when you brew your favorite Ruci roast, we know that you will have an amazing morning experience. Perfecting the art of brewing coffee takes time, so don’t feel discouraged if you don’t get it right the first time around.
