How to Brew Chemex Coffee Guide


Invented by Dr. Peter Schlumbohm in 1941 and heralded ever since, the Chemex remains one of the easiest, most desirable ways to brew coffee. This brewing method is known for producing an extremely clean cup, due to the heavy filter that is used. The Chemex with our proprietary metal filter is Coava's hand brewing method of choice.

Before You Brew

Fresh Coffee The single most important part of a good cup is starting with high quality, freshly roasted coffee. We aim to drink our coffee within a 14 day window of being roasted.

Purified Water Start with filtered water for best results. If your tap water already has a lot of dissolved solids then it will negatively impact your ability to brew the coffee.

Scale Consider purchasing a scale for your brewing. You'll find it will really boost the consistency and quality in your morning cup of coffee.
