This problem seems quite normal. Over time, the little holes are filled up with small coffee grounds and stuck there by the help of glueing force of grease. This grease is extracted during brewing process. So, how could we get rid of these remains? Pretty easy. As they are organic compounds, you should dissolve them. As they include grease, dissolve the ...

This could depend on the brand of filters and the brewing method so it's worthwhile (and fun) to do the experiment. I'd love to see results from more experimenters. Bamboo vs. Paper Filters: I did this experiment. We only had three tasters but the results were statistically significant at the 5% standard -- all three of us could taste the difference. The ...

What you're talking about is the "Japanese iced coffee" method, which is hot-water brew directly over ice. In contrast, cold-brew is using cold water in contact with the grounds. See techniques at other questions tagged as cold-brew. This article from Counter Culture, also referenced in the article you linked, suggest Japanese iced as an alternative to cold ...

I would advise against using soap to clean anything coffee related. As a simple measure, just use boiling water to loosen the oils. You can also use citric acid (the recommended cleaner for coffee machines), you can find it online pretty cheap. Another option would be to soak it in baking soda to dissolve the oils. Whatever you use, just make sure you rinse ...

Science! What follows is my bogus hypothesis, with pictures (annotated in the conventional style) and annotations to bolster my unsubstantiated claims. Other (non-Chemex) cone-style (and basket-style) filters often have ridges down the inside of the cone. It seems that these ridges serve two purposes: to provide channels down which the coffee can flow, and ...

Here's a few more things to add to @fredley's answer. Since the water is going to be in contact with the grounds for a longer time (1- using greater volume of water, and 2- Chemex filter will be slower) you're going to get more of the bitter notes that you get (in general) by using a longer brewing time. Acidity will be offset somewhat by the bitterness. I ...

So there are two main differences between the Chemex and V60: The V60 has a much finer filter than the Chemex, so extraction is much faster through the V60 filter, and more oils/solids come through. The V60 also has ridges, allowing coffee to easily pass through the filter evenly, rather than all having to exit through the bottom - washing out the grounds ...

Ever considered cooling your coffee down to 40 degrees immediately after you brew it? This would keep the freshness as well as not dilute it. Check out this link.

When I hear "cold brew" I think something like Dutch Coffee, or coffee brewed with cold water and long extraction times. Acidity likely wouldn't be reduced by cooling the coffee directly after, it's possible that the melted ice is just diluting your brew and cooler temperature mellows out the taste of the acidity. There are many ways of cold brewing. Some ...

Depends on if you want to be able to grind true espresso grinds. My daily grinder I received as a wedding present and it suits me just fine, a Cuisinart for about $40 dollars. If I want to grind for espresso, this is completely incapable of doing so, so I ended up getting a $180 dollar unit that is capable of timed grinding and grinding to espresso level ...

The only thing that I've found that I've found that works elegantly, quickly, and completely is ultrasonic cleaning. After boiling with vinegar water, lots of rubbing and scrubbing, high pressure steaming, and even ten minutes in a pressure cooker, it seemed to only get a bit more clogged. I set it in a small inexpensive ultrasonic cleaner I received as a ...

I tried boiling in vinegar and washing in the dishwasher over my bottle jets the other day. It did improve the flow situation greatly, but the filter was still brown. So I ordered urnex coffee equipment cleaning powder off amazon and two days later my filters are like new. I just boiled my cone filters and added a teaspoon of the powder. Here’s my water ...

According to the official website for the Chemex products, the filters available for the Chemex are: CHEMEX BONDED FILTERS PRE-FOLDED CIRCLES (FC-100) CHEMEX BONDED FILTERS PRE-FOLDED SQUARES (FS-100) CHEMEX BONDED FILTERS PRE-FOLDED SQUARES (NATURAL) (FSU-100) CHEMEX BONDED FILTERS UNFOLDED HALF MOON (FP-2) The 10 cups Chemexes, are: - TEN CUP GLASS ...

Use a water flosser, like waterpik to blast the coffee oils out. I tried boiling and vinegar, no use. Mini-pressure washer worked best. Water moves through the filter much faster.

To begin, the Sweethome review The Best Coffee Grinder is quite helpful for background and their experimental evaluation of grinders, although of course they only tested a modest number of the available grinders. Sweethome says what a grinder needs to make tasty coffee is to produce consistently- and uniformly-sized coffee grounds because coffee extraction ...

Honestly, I think you simply just need to coarsen your grind. Also, make sure you align the thick part of the filter (that has more layers) with the spout on the chemex. This just allows air to pass through which helps the percolation.
