Thermal Mass and Brewing Temp: The Aeropress Paradox
⏱ 1 min read The Short Version Boiling water in an Aeropress cools to 90°C due to its thermal mass, not just heat loss, making thermal mass the key factor in brewing temperature, not the initial water heat. In This Article Thermal Mass as the Real VariableThe Optimal Temperature Debate Pouring boiling water into an Aeropress isn’t just about temperature—it’s a matter of heat transfer efficiency. Your kettle’s 100°C water cools rapidly as it meets the coffee and vessel, but how much? A test showed the brew temp stabilized at 90°C, raising questions: Is this ideal, or does the initial…
