The source's pour-over tips begin with the way a paper filter sits in a conical brewer. A small adjustment to its fold can change the fit, giving the user a practical detail to check before making more elaborate equipment changes.
Fit is only part of the preparation. Rinsing, arranging the coffee bed and pouring consistently all affect how a comparison can be interpreted. Avoid treating one imperfect fold as a complete explanation for every disappointing cup.
Keep dose, water quantity and grind stable while examining one preparation detail. Record the flow and taste rather than relying only on how neat the bed looks afterward. The source's preference for pour-over is a personal viewpoint; these checks are useful because they improve repeatability within the method, not because they establish its universal superiority over other ways of brewing.
