How to Get Oils in Pour-Over Coffee? The Key Role of Coffee Bean Lipids and Filter Selection Explained
Can pour-over coffee have oils? The answer is yes, but it requires a different approach. The crema of espresso is essentially oil encapsulating carbon dioxide, and it is the lipids in the coffee beans themselves that truly give coffee its rich body and aromatic boost. Because pour-over uses a filter paper with excessively strong filtration, it is nearly impossible to retain oils. To change this, you simply need to switch to a device with slightly weaker filtration performance, such as a flannel cloth or non-woven filter paper, and Front Street has clear recommendations on this. This article will explain the mechanism by which lipids work and compare in detail the pros and cons of different filters and the key adjustment points, to help you achieve a richer mouthfeel in pour-over.

How long can coffee beans be stored after grinding into powder? Analyzing the shelf life difference between coffee grounds and coffee beans

This article will analyze in detail the freshness preservation differences between coffee powder and coffee beans, and share practical storage tips to slow aroma loss. [more…]
