The Right Temperature of Water to Use When Brewing Coffee with an Aeropress

published on: 2022-05-31

Brewing coffee with an Aeropress can be a lot of fun, but it’s important to use the right water temperature if you want to get the best results. If the water is too hot, it can scorch the coffee and make it taste bitter. If the water is too cold, it will not extract all of the flavor from the beans.

So what’s the perfect water temperature for brewing coffee with an Aeropress? It’s between 195-205 Fahrenheit (90-95 Celcius).

Why is that the perfect temperature? Water boils at 212 Fahrenheit (100 Celcius), so using water that’s just below boiling will ensure that your coffee doesn’t get scorched. And since water at this temperature will still be hot enough to extract all of the flavor from the beans, you’ll end up with a perfectly brewed cup of coffee.

What if you don’t have a thermometer or a water boiler where you can set the temperature?

If you don’t have a thermometer, you can boil water and then let it sit for about 30 seconds before using it. This should give you water that’s around 200 Fahrenheit (93 Celcius).

If you can set the temperature with a water boiler, set it to 200 Fahrenheit (93 Celcius). That temperature will give you water that’s hot enough to extract all the flavor from the beans without scorching them.

Does the temperature change if you use different beans?

The water temperature won’t change based on the type of bean you’re using. However, the grind size will have an impact on brewing time. If you’re using a coarser grind, you’ll want to brew for a longer amount of time. If you’re using a finer grind, you’ll want to brew for a shorter amount of time.

That’s because the finer grind will have more surface area exposed to the water, which means that it will extract more flavor in a shorter amount of time.

The reverse is also true - a coarser grind will have less surface area exposed to the water, so it will take longer to extract all of the flavor from the beans.

Does roasting level matter for Aeropress water temperature?

No, the water temperature will not change based on the roast level. A darker roast tastes different than a light roast, but the water temperature will remain the same. The coffee to water ratio for Aeropress will have a bigger impact on the taste than the water temperature.
