The secret to choosing the right type of coffee to make cold brew at home

Cold brew utilizes immersion brewing at room temperature or below. Specifically, the coffee is coarsely ground and steeped in water for up to 24 hours). During this extraction process, the coffee’s flavor compounds dissolve into the water. When the extract reaches a certain concentration, we just need to filter the coffee residue out to use immediately or store it in the refrigerator.

Cold brew preparation time is longer than other methods, on average 8 – 24 hours. This is because, at low incubation temperatures, water molecules have little kinetic energy. The extraction reaction is slow, making the process take longer. The long extraction time results in a higher total dissolved solids (TDS) product and more compounds and caffeine than other methods.

Traditional, cold brew is often applied to medium-roasted coffee, resulting in a bright acidity and natural sweetness. The flavor is rich, smooth and tends towards sweetness. Cold brew coffees will have many flavors in the caramel & chocolate group or the nutty & cereal. However, the coffee roaster has now expanded testing with a variety of light-roasted coffees of different origins for this method. Therefore, many cold brew coffee products today will have a certain acidity with the delicate flavors of citrus fruits and tropical fruits.

But the most important thing in shaping the flavor is The key is to use high-quality and suitable coffee beans. According to experts, this must consider the coffee drinker’s wishes and factors, including origin, preparation and roasting profile.

Consider the coffee origin

For those who want to highlight the unique characteristics of their coffee, single-origin coffee is ideal. When the composition of the beans is uniform, the extracted flavor will be clearer, more consistent, and sharper. While blended coffees offer diverse flavors, the flavor profile can become unbalanced if the ratio isn’t well-controlled.

If you want a cup of coffee with a sweet flavor profile, you can choose coffees from Central or South American regions such as Colombia, Peru, and Ecuador.

These types of coffee, when cold-brewed, will exhibit higher acidity within the Citrus flavor group.

Preprocessing method

With washed-process coffee, we will have a cup of coffee with high acidity and naturally light sweetness. When cold brewed, this type of coffee will deliver a bright, fruity flavor and high cleanliness. For natural-precessed or honey-processed coffee, there is a higher sugar content. These types of coffee often produce a much sweeter, richer taste.

About roast profile

The flavor profile of a cup of coffee often changes depending on roasting methods. Lightly roasted cold brew coffee is naturally sweet with good acidity. Medium to dark roast coffees will contain more sugar thanks to the longer roasting time. Therefore, if you love a sweet cup of cold brew, consider using medium or dark roast coffees. However, if the roast profile is too dark, you may extract large amounts of bitter, astringent flavor compounds, which add to the unpleasant experience.
