Never, ever can you burn your coffee. Due to the extremely high temperatures at which Specialty Coffee is roasted, adding 200°F water won’t further cook it. We have a few fixes in store if you’re complaining that your coffee tastes bitter or burnt. Let’s study why your coffee tastes so awful as we look at roast level, extraction, grind size, brew temperature, and machine maintenance.
Dark Roasts
First, coffee is naturally bitter. Speciality Coffee Just because coffee has an ashy, smoky, or burnt flavor doesn’t mean it must be bad. It can mean that you merely detest that particular coffee. These deeper characteristics are more apparent in some coffees than others depending on the type, region of production, method of processing, and method of roasting. Coffees with these subtleties are often roasted darker to enhance them because they are popular flavors.
Extraction
When water is added to coffee, extraction occurs. Some components of coffee extract dissolve more easily than others. As a shot pulls, the acids and fats are the first to extract. These give your shot more juiciness, body, and clarity. After that, sweeteners will soften and complement the specialty coffee. Not to mention, as plant fibers separate from the coffee, it could start to taste bitter and astringent. The amount of extract you get can be altered by adjusting the brew time. The longer a shot is played, the more bitter it becomes. Because of this, ristretto-style, shorter servings of darker-roasted coffee are frequently used.
Grind Size
Your grind size has an impact on extraction. It is easier for water to access the coffee and extract nutrients from it when there is more surface area and a finer grind. Finer grinds will therefore extract more than coarser grinds when brewed for the same amount of time. As we just mentioned, dark roasts are more soluble, so you might need to ground them up more coarsely to prevent over-extracting.
Temperature
Changing the temperature of your brew will be quite helpful if your equipment supports it. The hotter the water is, the more you can extract. If your coffee tastes bitter, try lowering the temperature to use less extraction. The ideal temperature for espresso is between 195 and 205 degrees Fahrenheit. If you’re using a darker roast, a good place to start would be in the 195-200 area.
Cleaning
to clean something. Check to see that your espresso machine is clean and that the portafilter, basket, or group head aren’t covered in coffee grounds or oil if you’ve done the aforementioned advice but your coffee still doesn’t taste fantastic. Run a hot water rinse cycle and detergent rag backflush to make sure everything is thoroughly clean.
