Coffee Science Publications (5)
Welcome back to this third and final issue of organic acids. In the last issue we briefly discussed the role of quinic, caffeic, and citric acid and its role in coffee’s flavor. This time we will explore acetic and malic acid and see how these seemingly simple acids play a major role in coffee’s complex flavor profile.
Last month we briefly discussed the role of chlorogenic acid (CGA) and its decomposition during roasting. This month we’ll focus in a bit more on CGA’s secondary compounds and introduce citric acid in an effort to understand its affect on overall quality.
Welcome to this month’s issue of coffee science. In our last series we discussed the role of two alkaloids: caffeine and trigonelline and their role in coffee’s composition. This time we’ll explore some of coffee’s more common compounds, namely carbohydrates and proteins, and discuss how these seemingly ordinary compounds contribute to coffee’s alluring aroma.
Everyday millions of people around the world begin their day religiously with a morning cup of coffee. Though today we easily identify coffee in its beverage form, it wasn't always this way in the beginning.
