About

You love coffee and you love coffee from your French press even more. The exquisite aroma and vision of the coffee oils floating to the top makes coffee aficionados the world over prefer to press and pour.

               

 Nevertheless, many coffee drinkers have set their French press aside to avoid the mess that comes with cleaning. It consumes more time, smudges your sink, clogs your drain and requires a lot of tap water or kitchen parer to clean up the presses messes.

With your support, we can solve the problem once and forever.
We’re giving you back your French press pleasure without any of the pain.

Say hello to GRUMS - a brilliantly simple “cup” that collects your grounds for easy disposal while keeping your carafe clean. We’re developing the ideal receptacle for your grounds that automatically fastens to the plunger when you pull it from the carafe to empty and clean it. GRUMS saves you time, effort, water, and eliminates clogging of your drain. Just shake your grounds out from the cup to your trash bin or save the grounds for a variety of helpful uses (more on that later).

You’ve just made a nice cup of coffee from your French press, and now your carafe is filled with coffee grounds. Time for clean up! The coffee grounds are thrown into the sink and now you rinse the carafe and the sink with lots of water. Wasteful and messy! 

With GRUMS, you simply add your fresh coffee grounds into the GRUMS cup, set it inside the carafe, fill with water, and press down the plunger.

Now comes the magic.

After you’ve enjoyed your delicious cup of coffee, gently push the plunger in the GRUMS cup and let friction work for you to effortlessly pull out the grounds – compacted nice and tidy inside the GRUMS cup. After lifting the cup out, all the grounds can be thrown into the trashcan, or set aside for other meaningful uses.  

We set out to create something so smart, simple and easy, French press coffee lovers wouldn’t think twice about purchasing one.

With GRUMS, you get the taste you want without the mess you don’t. Just fill up GRUMS with your favorite coffee until you reach one of the markings of your liking. Place the cup into the French press, pour your hot water, press, and then enjoy a nice cup of coffee. Afterwards, the plunger is automatically fastened to the cup, which easily can now be removed to throw out the grounds or even keep it for later purposes – How simple is that?

In Denmark, where GRUMS is being developed, we are passionate about conserving resources to benefit people and our planet. Much of our inspiration for GRUMS is a result of not wanting to waste water. On average, it takes about 4-liters (more than a gallon) to clean your carafe and sink – even more if your drain clogs.

Lets say we put it conservatively at 2 liters minimum to clean you carafe after use. Taking into account the number of French presses sold up to now, and the average use (1-2 times a week), we get to a stunning water consumption of 104.000.000 cubic meters (27,473,893,445 gal) pr. year. That’s enough to fill about 7 million tanker trucks. The length of all these trucks combined equals to more than two times the circumference of the Earth.

Let us remind our selves that only 1% of the world’s water is fresh water, and this water needs to be made drinkable before it comes out of our taps. The energy required to make water drinkable is substantial. By using water to clean a carafe with coffee grounds, we’re wasting the world’s precious supplies of water.

USING GRUMS can save 100,000 tons of CO2
This is the energy it approximately takes to collect, pump, distribute and again drain off all this water. According to the Danish Danva water association it takes about 1 kg CO2 per 1000 liters. So we use not only a lot of water but also 100,000 tons of CO2 to deal with it. Lets save this too.

GRUMS is not made for any specific French Press brand, but for the standard 1-liter jar that is most commonly used. GRUMS will fit right into what we believe is more than 95% of French press carafes being sold today and at least all the major brands.

If you're concerned about fit, take a measure at home before you pledge.
The outer dimension of GRUMS is 90 mm (3.5-inches), so your carafe should be a little larger than that.

Save the grounds and re-use them – Coffee grounds can be used for more than 20 different purposes including surprising things, like fungus and soap making.

Brewing coffee is actually using a small percentage of the nutritional value inside the bean; so don’t throw your grounds in the trashcan.
Coffee grounds contain rich amounts of nitrogen and function as a perfect natural fertilizer for your plants. By adding organic material to the soil, you will improve drainage, water retention and aeration.

You can also use it to absorb food odor. Simply place your coffee grounds in an open container and leave it inside your refrigerator. After a few weeks, you can still use the same coffee grounds as fertilizer. 

It also makes a great exfoliating body scrub. Mix your coffee grounds with a bit of warm water and you’re ready to exfoliate your skin.

We’ve made it easy for you to make French press coffee. We’ve designed markings inside of the cup, so you can easily fill it with the right amount of coffee for you. The markings make it more consistent than spoon measuring.

When it’s time to clean your carafe, you’ll see why GRUMS is the one French press accessory you never want to be without. Because all the grounds remain nice and tidy inside the cup, there’s less grounds residue to clean up in the carafe and in your sink. Just knock the grounds out in your bin. Imagine how much water you’ll save, and how much easier it is to enjoy another cup.

Get ready in seconds and get ready again. It’s Friday night and you’re having a dinner party with all your best friends. Normally you would choose the coffeemaker because you need to make multiple pots, but to be true to yourself, you prefer the French press way. With GRUMS, you can clean the used carafe quickly and have it loaded again and ready to go.
Imagine the compliments you’ll get serving your guests delicious and aromatic French press coffee.

Did you know that you can use your French press for more than just coffee? What about brewing a carafe of tea instead and still use GRUMS to help you clean up easily afterwards?

11 prototypes and 2 years of work to get it just right
11 prototypes and 2 years of work to get it just right

Although the idea of GRUMS is simple, those ideas are often the hardest to bring into reality. Though the design of GRUMS looks similar to any other small bowl or container, there’s so much more than what meets the eye.

First, the outer diameter was one of our greatest design challenges and our most proud accomplishment. After attempting numerous variations of wall thickness, diameter, height, and shape of the outer wall, we finally landed at 90 mm diameter and a 1 mm wall thickness for GRUMS (see below) to effortlessly pass into the carafe.

At the same time, the groove pattern on the side of GRUMS is an essential design component. The grooves allow for water to pass and relieve the amount of vacuum and suction created at the bottom of the glass carafe for easy removal.

Even the logo on the lower side of GRUMS plays an important role. Notice how it is elevated to assist in the removal of the cup as you lift the plunger. Honestly, without these small technical tricks and design features the product would not work as effectively as it should. Instead, the carafe piston/filter would be pulled out of GRUMS during lifting procedure.

The Knock-box is not complicated
A small bin and a cross bar.
The lid is easy to move as its made as a sliding- turning lid like on a old tobacco can. The bin content will hold you about 20 pcs of Grums 

Small grooves on the side will ensure some air ventilation to the inside that will prevent mold to build. 

Just knock a few times to empty the Grums

Finding the right material is our next challenge.

Thus far, we have so far only made prototypes, but we are encouraged that medical Polypropylene, Nylon or ABS will do the job. We will test all of these materials to see what is best – both in terms of molding and in use.

In use, we aim for a material that elongates and retracts to a minimum. As our unit is thin, we look for good flow in molding. And finally, we must only consider food grade materials that are 100% free from migrating any harmful components. We also realize that some people may have an aversion to synthetic material, so we are also considering ways to make GRUMS in aluminum, but that extension will only happen after we’ve perfected the original GRUMS we’re proposing to you now.

 We can make our first mold tooling.

Once we receive our moldings, we will test and retest every facet of the unit. We will be vigilant in improving the material and the design. It may mean adding 1/10 mm here and there, but we won’t be satisfied until we know we have perfected GRUMS. Once we’re confident to proceed, we will make 4-cavity tooling to bring down production cost and really set this concept on fire. Your backing will not only help us financially, but to also spread the word and encourage us in the belief we have done something right here, something good for you, our future customers, and our planet.

Tobias had this idea.

I started using the french press in my early twenties. It was the beginning of the nineties with Nirvana playing on the radio. The cold war was over, and the world was bright and promising.

I lived in a small flat in Copenhagen and I enjoyed my french press coffee to the fullest, but the cleaning was annoying.

If I flushed the coffee grounds, my drain would clog, so I often found myself scraping the grounds into the bin with a wooden spoon. I started thinking that there must be a better way. While I was studying industrial design at the Royal Academy of Architecture, I got an idea:
Why not collect the grounds in a cup that could be removed with the flick of your wrist?

I drew the unnamed gizmo, but I was concerned someone would steal my invention, so I didn't show it to anyone. Later, I contacted the company that made my coffee maker, but got turned away at the reception, “We do not cooperate with outside designers,” I was told.

The project ended in a drawer for 20 years.

I had a career in television for 17 years, but when I got sick and lost my job, I needed a new occupation. I looked at my old ideas. That French press ‘gizmo’ jumped to the forefront. As the 3d-printer was now in existence, and better yet, the University had one I could use for free, I made a prototype - Eureka! It worked.

No longer afraid to show it anymore, I contacted several firms. I knew I had to trust people or it would sit in the drawer once again. It took me two years to find Lars and Fabrikators. We met in November 2015. The idea has a name: GRUMS.

Now it's up to you. Do you like my idea?

Thank you for giving us your time.

At first glance, the image below may look like nothing more than a few grams of plastic, but in reality, the design entails some unique engineering and design characteristics.

Nevertheless.   
Lets face it - GRUMS could come into the hands of people who may attempt to copy our concept and designs. To protect ourselves from copycats, we have filed for an international patent we hope will take some of the air out of their efforts. We are relatively sure the major players will leave us alone for a while or seek a license deal. With your support, we will stand a better chance of protecting the idea.

Risks and challenges

We have worked more than 24-months to construct the perfect grounds keeper - and we are 99 % sure we got it right.

But nothing is 100 % before we get the molds opened.

See the result - get the user testing.

Test the materials.
Adjust cooling, heating, injection points, float lines, dimensions, flares, finish, surfaces, deformation, etc.

Test and retest, and repeat over and over again.

We will be absolutely sure the fundamental function will work. Even our
prototypes have performed adequately even when exposed to water heated to 100 degrees Celsius (212 degrees Fahrenheit).

Now, it’s time to make the real ones and begin marketing GRUMS to people who love coffee.

In the future, we hope to make an aluminum version. Aluminum offers better material properties, but requires a greater learning curve for us and may take more time. Hopefully, this effort can be financed through the success of GRUMS.

In addition, we are also planning on making a "knock-box" for easy storage of grounds for reuse.

This is an exciting time for us.

Thank you for your support.
