Brew Style: Filter Drip
Materials: Cloth coffee filter for 6-10 cup Chemex
The Coffee Sock Chemex Filter is an innovation from CoffeeSockCo., a family owned company out of Austin, Texas. Their mission is to create reusable filters that help minimize the need for producing paper filters- “Save the trees.” as their site says.
The shape and use of the organic cotton filter is much the same as the paper ones. Before its first use it needs to be boiled for about 5 minutes for rinsing and initial shrinking. At the outset of each brew the filter will need to be rinsed with water just as you would a paper filter. The only real difference that I noticed when using the Coffee Sock filter was a slightly increased speed of the water passing through the grounds. I attribute this to the difference between cloth and paper when it comes to flow restriction.
I toyed with a couple of ways to compensate for this. First I tried making the grind a notch finer on my Vario macro settings than I normally would for a paper filter, which resulted in a balanced, but heavier bodied result. It had sweetness, but the acidity was harder to detect. I also tried keeping the grind the same, but the water level a little lower than I normally would through the brew process (only a little over halfway up the cone), which provided the result I was more accustomed to. This does take a little more interaction through the brew process. The finished product makes a little more room for acidity with its lighter body.
Clean up, while not as simple as lifting the filter and throwing it away, isn‘t very complicated. Admittedly it is a little more messy, but it is no more than what would be expected with a reusable filter. The construction is durable, with reinforced stitching and the cloth being of a dense and heavier cotton weave. The site claims that one filter can last for a full year if properly cleaned and taken care of. For the cost of $10, I would say that it’s well worth the savings on filters, as you get a nearly identical cup of coffee.
