More coffee nerdiness
It’s not a law, but the rule of thumb is +10°C _doubles_ the rate of chemical reactions*.
If we take the ‘typical’ rule of thumb for coffee brew water temperature, we get:
195-205°F = Δ5.6°C ∴ ±~56% change in reaction rates, and every 1°F represents approximately 5% change in the rate of reaction. Think about this when your brain are hyper-focused a scale while trying to get your 350g brew water weight precision down to 1.0g (which is 0.2%).
*-the classic rule of thumb on rules of thumb is that thumbtimes it’s true, thumbtimes it isn’t.
