I now suspect that astringency is caused by large molecules that barely dissolve in water; they can be kept away from our cup of filter coffee if we don't use pressure or suction, have a thick coffee bed and even flow of water, in order for the coffee bed to filter out these large, undissolved molecules. Karl Wienhold is a researcher, consultant, and operator of post-colonial rural development, specifically the intersection between agrarian communities and the global economy, endeavoring to understand and undo extractive power structures in favor of equitable alternatives. One thing I think is still very much under appreciated in espresso is how the viscosity of coffee can impact the flow rate and how it evolves during a shot.
