Coffee Myths

Debunking coffee myths for better brewing

Making a delicious cup of coffee is all about the effort and confidence you put into the brewing process. “Coffee Myths” is focused on busting common misconceptions about coffee and ensuring that consumers have accurate information about their favorite beverage. Don’t let myths and misconceptions get in the way of experiencing the natural and rich flavor of your coffee. 


To ensure that your coffee is brewed to perfection, it’s important to separate fact from fiction. Here are a few common coffee myths that you should be aware of.


[MYTH 01] Dark roast contains more caffeine

There’s a common belief that dark roast coffee contains more caffeine than light roast coffee. However, this is simply not true. The roasting process plays a crucial role in determining the taste and aroma of coffee, but it does not significantly impact the caffeine content. In fact, the more coffee is roasted, the more it loses mass, which includes some of the caffeine molecules. But the difference is so small that a person drinking coffee would not notice any variation between dark and light coffee. It’s essential to understand that caffeine levels depend on several factors such as the type of coffee bean, its growing region, and processing methods.

[MYTH 02] Light coffee roast is less complex

Coffee lovers have long debated the superiority of dark or light roast coffee, but the truth is that both offer unique and delightful flavor profiles. Despite popular belief, the caffeine content in coffee beans does not vary greatly based on the roast level. Light roasts tend to retain more of their origin’s acidic and flavorful qualities, while dark roasts boast rich and robust notes of chocolate, spices, and nuts. However, it is important to note that the intense roasting process can also overpower the natural flavors of the coffee bean. So, whether you prefer the bright and fruity taste of a light roast or the bold and rich flavors of a dark roast, the decision ultimately comes down to personal preference.

[MYTH 03] Strong coffee is created during the roasting

The popular belief that coffee strength is directly related to the darkness of the roast is a common myth. In reality, the strength of coffee is determined by the ratio of coffee grounds to water used during the brewing process, not during the roasting process. A dark roast may taste bitter, but it does not necessarily mean it is stronger. It is important to understand that roasting only affects the flavor profile, not the strength, of the coffee. So, the next time you brew a cup of coffee, remember to focus on the ratio of grounds to water, and not just the roast level, to achieve the desired strength.

[MYTH 04] Oily beans are fresher beans

Many coffee lovers associate a shiny and glossy appearance with the quality and freshness of coffee beans. However, this is a common coffee myth that has nothing to do with freshness and everything to do with the roasting process. The appearance of oiliness on coffee beans is a result of the heat generated during the roasting process, particularly in darker roasts like French roast. As the temperature rises, the skin on the beans ruptures and the pores open, allowing the natural oils to escape, creating an oily appearance.


To ensure that you are getting the freshest coffee, it is important to source from small batch roasters, purchase only what you plan to consume within a two-week period, and store your coffee beans properly. By following these simple steps, you can guarantee the best possible taste and quality of your coffee.

[MYTH 05] Espresso is its own special kind of coffee roast or bean

Contrary to popular belief, espresso is not its own unique type of coffee roast or bean. The secret to its rich, full-bodied flavor and intense strength lies in the brewing process. The finely ground coffee beans used in espresso are carefully prepared with a specially designed, high-pressure machine that extracts the delicious flavors and aromas from the coffee grounds. The type of coffee roast used in espresso preparation can vary, and can range from light to dark roast. This means that any roast can be used to create a delicious cup of espresso, making it a versatile and highly sought-after coffee variety. The key to a great cup of espresso is the combination of high-quality coffee beans, the right brewing method, and the proper coffee-to-water ratio.

[MYTH 06] Bold coffee is the same thing as dark roast

One of the widely-held “Coffee Myths” is that Boldness and Dark Roast are interchangeable terms. This is a misconception. Boldness in a cup of coffee is not determined by the roast, but by the brewing method. In order to create a bold cup of coffee, you must use a higher ratio of coffee grounds to water during the brewing process. This increased proportion of coffee to water results in a stronger flavor and higher caffeine content. However, it is important to note that a bold cup of coffee can be made with coffee beans that are roasted light, medium, or dark. This debunks the myth that boldness is synonymous with dark roast.

[MYTH 07] Immediate use of newly-roasted beans for brewing fresh, great-flavour coffee

One of the keys to producing a delicious cup of coffee is ensuring that the beans are fresh. However, many people hold the misconception that using newly-roasted beans for brewing will result in a great-flavored coffee. This is not always the case.


The roasting process generates carbon dioxide by breaking down sugars and amino acids in the beans, which leads to a build-up of carbon dioxide that releases over the next 12 to 72 hours. If you brew your coffee too soon after roasting, the beans may not have de-gassed properly and this can result in a slightly bitter, sour aftertaste.


It’s important to understand that coffee beans need time to rest after roasting. It is recommended to wait until the roast date has passed and to look for the peak cycle of the coffee, which starts on day two or three and begins to taper off around day ten to fourteen. By allowing your coffee beans to rest, you will ensure that the carbon dioxide has properly released and that you are brewing a coffee that is full of flavor and without any bitter, sour aftertaste.


[MYTH 08] Freezing coffee will maintain freshness longer

The myth that freezing coffee will help maintain its freshness is just that, a myth. While it may seem like the perfect place to keep your coffee, the freezer or refrigerator can actually do more harm than good. Coffee beans, whether they are whole or ground, are porous and absorb the air around them. These environments are often too damp for coffee, which can lead to compromised flavor and can also result in the beans absorbing unpleasant refrigerator odors or becoming freezer burnt.


When it comes to preserving the freshness of coffee, it’s important to keep it away from air, moisture, and heat. Instead of the freezer or refrigerator, store your coffee in an airtight container in a cool, dark place such as a pantry or kitchen cupboard. By doing so, you can ensure that the flavor and aroma of your coffee stays intact and enjoyable to the last sip.

[MYTH 09] Pre-grind coffee bean for storage to maintain freshness

One of the persistent coffee myths is that pre-grinding coffee beans helps to maintain their freshness. However, this is not the case. The process of grinding coffee beans causes them to lose their freshness much more quickly, no matter how you store them.


When coffee beans are ground, their oils are released and they are exposed to air. This exposure to air is one of the key factors that causes coffee to go stale, making pre-grinding coffee beans an effective way to speed up the staling process. The flavor of the coffee will be compromised, and this is especially true for flavored coffees.


For the best possible flavor, it is recommended to buy whole coffee beans and store them in an airtight container in a dark place. Only grind the beans right before brewing. This way, the coffee will remain fresher for a longer period, and you’ll be able to enjoy a delicious, flavorful cup of coffee every time.

[MYTH 10] Vacuum-sealed packaging equals fresh coffee

One of the common misconceptions about coffee is that vacuum-sealed packaging guarantees freshness. However, this is not entirely true. During the coffee roasting process, coffee beans release a by-product of gas, specifically carbon dioxide. This gas release continues for several days after roasting. To be vacuum-sealed, the coffee must first release all its carbon dioxide or it will burst the bag, meaning it has to sit around for several days before it can be packaged and shipped, which begins to impact its freshness.


While vacuum-sealing is suitable for pre-ground coffee, which tends to not taste as good as freshly ground coffee, the best packaging and shipping method is in valve-sealed bags. These bags allow the carbon dioxide gases and moisture to escape but prevent oxygen and moisture from entering. This allows fresh roasted coffee beans to be packaged and shipped immediately after roasting, preserving their freshness and taste.


[MYTH 11] The hotter, the better

The temperature at which coffee is brewed can greatly impact its flavor. A common misconception is that the hotter the water, the better the coffee will taste. However, this couldn’t be further from the truth. Pouring boiling water over freshly-ground coffee beans can actually destroy their delicate flavors.


To get the best taste from your coffee, it’s important to brew it at the right temperature. The ideal range for hot coffee is between 155°F to 175°F (68°C to 77°C). This temperature range helps to preserve the delicate flavors and aromas of the coffee. However, if the temperature goes above 175°F (77°C), the rate of oxidation increases, leading to a bitter taste. And if the temperature exceeds 205°F (96°C), which is close to boiling, the coffee can become burnt, replacing its desirable flavors with a bitter and charred taste.


Therefore, to enjoy a rich, flavorful cup of coffee, it is advisable to brew it at the optimal temperature range and to avoid over-heating it. This way, you can preserve the true flavors of your coffee and savor the subtleties that make it special.


In conclusion, BrewRatio aims to correct common misconceptions about coffee and provide accurate information to help consumers achieve a delicious cup of coffee. The above debunks several popular myths about coffee such as the notion that dark roast coffee contains more caffeine than light roast coffee, light roast coffee is less complex, strong coffee is created during the roasting, oily beans are fresher beans, espresso is its own special kind of coffee roast or bean, bold coffee is the same thing as dark roast, and the immediate use of newly-roasted beans results in great-flavored coffee. In reality, the strength, flavor profile, and quality of coffee depend on various factors such as the type of coffee bean, the brewing method, the ratio of coffee grounds to water, and the freshness of the beans.
