Combining the French press and pouring-over methods, while improving both, is the goal of a new coffee-maker being promoted by an outfit called Immerset. The device is a project by inventor Chic Kelty, and is designed both for commercial and consumer purposes.

The key innovation of the Immerset is a stainless steel valve that allows the user to control the grind and the cycle of water going through the coffee. The ABS plastic housing was designed with durability in mind as well as ergonomics. No parts jut out as they do in pour-over systems, adding extra safety to the process. Inside, a stainless steel screen prolongs contact with hot water and helps create a void between itself and the housing, keeping the external wall cool enough for the hands.

Instead of pressing a plunger, the grinds are separated from water through the force of gravity. Because it uses a paper filter, there’s no limitation to grind types. Alternatively, reusable screen filters can be used instead of paper filters. The steel sleeve ensures flow even when coffee is made with very fine grinds.

French presses are very charming but they have their limitations. For one, they are limited to coarse grounds. Also, coffee does not come out super hot, as it tends to cool during the brewing. Finally, French presses are somewhat fragile, and tend to make a mess during cleaning. Pour-over coffee making devices usually have no integrated flow control – it depends on the person handling them.

Kelty is using Kickstarter to get his project off the ground. He adds that besides coffee, the device can also be used to make tea. To get an Immerset, backers can start with a pledge of US$35, adding $20 for shipping outside the US. Estimated delivery is May 2014, assuming the funding goal is met.

I don't see how this is different from the Clever Coffee Maker, except that this one has some stainless steel parts, and the Clever Coffee Maker is all plastic. However, there doesn't appear to be any difference in the brewing method. The CCM works well and is inexpensive. Still, I prefer an Aeropress.


Oh good... a French Press that is less carcinogenic!

Cleverbrewer? Aeropress? Really Benhiroshima? You must really like your coffee bathed in petro-plastics. This thing is much more professional looking is sheathed in Stainless steel! It definitely does not look like Chinese-plasti-product. Not to mention that the clever brewer is a hygenic nightmare. The aero press and the clever brewer I owned both became so gross in less than 3 months that I stopped using them for fear of my health! I hope Immerset gets funded! I'm tired of using/breaking my french presses (3 replacements this year, yes I am a clutz)

Water boy

Putting insulation on the outside of our french press should make for hotter coffee and make it less likely to break when dropped. maybe use an old can and some expanding foam like GREAT STUFF™.


I see absolutely nothing of a French Press in this device. At no time is the coffee or water pressurized. This is a nice little stainless drip coffeemaker with plastic exterior, and it has a flow control (aka shutoff valve.) I see $10, not $35, in the price, please.


Is it possible to explain how the dispense rate makes a difference when the coffee is immersed? I understand that once the coffee is immersed instead of the rate of flow beginning immediately it may be released whenever and at different rates. Would it be similar to pulling a shot with varying pressure from a machine like the slayer? The paddle allows for the flow of water to vary within a range yielding different espressos. I suppose here we would be dealing with different taste profiles. Correct to assume the immerset achives varied flavor profiles the longer the coffee is steeped over a given amount of flow over time? Is this the end goal for the product?

@ljaques A French press is not pressurized. French press is simply immersion and then "pressing" (more accurately "screening") the grounds out of the way to allow the coffee through. You're thinking of Espresso.

This product has a lot more in common with a dripper than with a French press. Though it does prolong the contact with the grounds by controlling the drip rate, which is advantageous.

The Incred-A-Brew and Clever Dripper have more in common with a French press than a dripper. All of these products are somewhere in between.

I have a stainless steel thermos french press that after you plunge it, you can seal it up and carry it in your bag. This thing makes far better coffee than my traditional glass french press, mostly do to containing the heat in the brewing and later after the plunge. The coffee stays warm for hours.

Far better than this IMHO.
