Increase the Dose: To avoid over-extraction, consider increasing the amount of coffee grounds you use to 30 and 35 grams. This can help ensure a balanced flavor profile.
Grind Coarse: A coarser grind can improve extraction by reducing fines and allowing water to flow more evenly through the grounds. Aim for 700-1000 microns (It should be coarse, like sea salt).
Inverted Method for Precision: The inverted method, where the AeroPress is inverted with the filter on the bottom, offers greater control over all variables in the brewing process. If it were upright, water would start pouring through straight away, meaning the process isn’t under your control.
Stir for Even Extraction: Gently stirring the coffee grounds after adding hot water can help ensure a more even extraction, preventing under-extracted areas.
Paper Filters for Optimal Results: While metal and cloth filters have their proponents, paper filters are generally considered the best option for achieving a clean, flavorful cup of coffee. They stop fine grains from ruining your extraction.
Dilute the Final Brew: The “bypass" method involves diluting the final brew with hot water to achieve complete control over strength and clarity. This can result in a cleaner, more refined cup of coffee. If you always end up with a brew that's too strong, consider this method to reign the final result in more.
