Kaffeologie sells the S Filter, an ultra fine stainless steel coffee filter for the AeroPress Coffee and Espresso Maker.
We’re Kaffeologie, and we make the S Filter for AeroPress® Coffee Makers. We have made other coffee filters in the past, and we have some really cool ideas for stuff we might make in the future, but right now we do the S Filter for AeroPress.
On our website you’ll find the S Filter along with the brewing gear we think goes best with the S Filter and AeroPress coffee brewing. You’ll also find some handy coffee brewing guides to get you started brewing with the S Filter.
We’re in business because we love brewing coffee ourselves and want to make brewing coffee easier and tastier. We’re a small business based in Seattle, and the S Filter is our first real product.
The S Filter is basically a taut sheet of ultra fine stainless steel mesh with some fancy engineering around the edges to keep it stiff and permanently attached to a super thin steel ring. Why steel? Because it’s safe to use and doesn’t contaminate the brewed coffee with other flavors (paper often leaves a papery taste behind in your brew).
The mesh is special too, since we determined the average diameter of coffee lipid bubbles (coffee oils) in the brew and then matched our mesh to that size so it would reliably allow flavorful oils through but capture all coffee fines larger than the diameter of a coffee lipid bubble.
If you’re interested in buying the S Filter, you can shop for it here. You can also check out our brewing guides and our S Filter wholesale information form. And if you have questions or notice a bug on this website (hey, it happens to the best of us!), please contact us.
Thanks for visiting, and happy brewing!
