What is distilled water and why is it not ideal for coffee?
Distilled water is water that has been purified through the process of distillation, which involves boiling the water and then collecting the condensed steam. This process removes impurities and minerals from the water, resulting in water that is very pure but also very neutral in terms of its chemical composition. While distilled water may be good for some uses, it is not ideal for making coffee because it lacks the minerals and electrolytes that are present in tap water or spring water.
These minerals, such as calcium and magnesium, play an important role in bringing out the flavors and aromas of coffee. Without them, coffee made with distilled water can taste flat and uninteresting. Additionally, the lack of minerals in distilled water can also affect the texture and body of the coffee, making it seem thin and watery. For these reasons, many coffee aficionados recommend using water with a balanced mineral content to make the best-tasting coffee.
What are the essential minerals for revitalizing distilled water for coffee?
The essential minerals for revitalizing distilled water for coffee are calcium and magnesium. These minerals are important for bringing out the flavors and aromas of coffee, and they also play a role in determining the texture and body of the coffee.
