Jonathan Gagné (Prismo)
Jonathan Gagné is an astrophysicist and coffee blogger from Montréal, Canada. He developed this recipe with an extremely long brew time in order to maximize extraction and sweetness, resulting in a flavor profile closer to a well-prepared pourover. This recipe requires the Fellow Prismo attachment; if using the regular AeroPress filter cap, look for the non-Prismo version of this recipe.
