| Metal filter for Chemex by Coava |
Once again my generous local coffee shop, Kaffemekka, have borrowed the Kone by Coava for a little review. I was noted by Kaffemekka staff that it could be a little tricky to use, because of the holes slowing the water flow of the extraction process.
Nevertheless this Kone created by Coava allows coffee drinkers to support the environment fight, by abolishing the paper filters. Keith Gehrke, co-owner of Coava Coffee in Portland, Oregon made this possible a couple of years ago when he started noticing the trend of wastefulness that paper filters allow. Instead of just letting it pass by, he took matter in his own hands and deleted the paper standard by creating a filter for his shop´s Chemex pour-over bar that would, once and for all, replace paper filters.
The reusable result was the Coava Kone coffee filter, the biggest advancement in coffee filtration methods in the past several years. Made in the United States; designed in Portland, steel from Ohio, etched and welded in Connecticut, the Kone is indeed a reusable and sustainable filter that is easy to wash (dishwasher-safe) and provides an always consistent pour.

Pros
- Using this brew method (Chemex along with the Kone filter) there´s a very little cleanup, because of the use of only two pieces.
- The Kone is dishwater-safe.
- You will never have to purchase paper filters again, this led to a more economical, more resourceful and more environment-friendly use.
- This specific product is fully produced in the United States, which is for the half of my viewers a local product.
- There is no paper taste which is interfering with the origin coffee taste.
- The Kone allows coffee oils into the cup, producing a more sweeter taste than paper filters allows.
Cons
- The Kone can be a bit tricky to use, the holes of the metal filter slows the water flow a bit.
- Its metallic, so the edges may be a little sharp.
- You can bend the Kone, which will ruin the filter.
- The Kone isn´t cheap and costs about $40-55, which is a bit pricy - but generate a saving after just a year of use, depending on how much coffee you drink.

| Extraction process of the Kone |
When you compare the traditional paper filter with the Kone by Coava, there´s a noticeable difference, because the filtered brew is more clean and clear, because of the better filtration system. The Kone delivers a darker brew with some sediment and oils, which is kind of like when brewing the French Press.
When you compare the taste between the two are they quite similar, but the major difference is that the Chemex filtered brew did a more clean, crisp and more light on the tongue, more like caramel. The Kone brew was slightly heavier on the tongue, with more earthly and sweeter notes.

My personal opinion is clearly that I´m most a supporter of the clean, sensitive and crisp flavors, which is leading me towards the paper filters instead of the Kone. I´m not a hugely fan of the French Press and brew ten times more a Hario v60 brew instead of a FP, but with that said if you are more in favor of a heavy, oily brew --> French Press, then you will be in favor of the Kone.
I think that this kind of innovation within the world of coffee should be rewarded with support from all coffee nerds, so try it out yourself and see if you follow me opinion or if you like it more than the filter brew.
All hands on the table, Keith Gehrke have created a fine filter with a lot of potential, but I´m not extremely glad for the rough brew (sediment and oils), that this filter leaves behind in the cup. Nevertheless I would prefer this brew method instead of a French Press, which is even more rough.
