Today I was on a quest to find out why coffees grown in highland regions are generally more dense, bright and have complex flavours. Yes, I know it's because the cherries have a slow maturation and they are influenced by the swing in temperature between day and night. But, I wanted to know more about what causes the slow maturation of cherries in Highland regions and what effect the swing in temperature causes to coffee profile. So, I dug deeper, and was amazed by how various biological factors and certain chemical processes are involved. My quest ended after finding all the answers I was looking for. I gotta say I feel a certain level of euphoria.
