What Type Of Coffee Is Best To Use With A Chemex Pour Over Coffee Maker?

When it comes to using a Chemex pour over coffee maker, the best type of coffee to use is a medium roast.

A medium roast coffee will have the perfect balance of acidity and sweetness, making it ideal for a Chemex brew.

Avoid using dark roast coffees as they tend to be more bitter and can overpower the delicate flavors of the Chemex brew.

It is also important to use freshly roasted coffee beans and grind them just before brewing to ensure the best flavor and aroma.

Brewing in a Chemex with Cold Water

While brewing with hot water is the traditional method for making coffee with a Chemex, it’s also possible to brew coffee with cold water.

However, this requires a different approach, known as the cold brew process.

The cold brew process involves submerging the coffee grinds in cold water and letting it steep overnight.

This slow extraction process allows for maximum flavor extraction, resulting in a smooth and less acidic cup of coffee.

Once the coffee has steeped, it is filtered to remove the grinds, and the concentrate can be diluted with water or milk to taste.

It’s important to note that if you use too cold water when brewing with a Chemex, the coffee may be under-extracted and taste weak.

On the other hand, if you use too hot water, the coffee may be over-extracted and taste bitter.

Therefore, experimenting with different water temperatures is crucial to finding the perfect temperature for your Chemex and personal taste preference.

Brewing with cold water is possible with a Chemex through the cold brew process.
