Coffee Tester Set · Coffee Battle 2026
Everything you need for the Coffee Battle. You bring the taste.
Don't have an ARCA yet? Then this is your entry point. The Coffee Tester Set contains the complete Explorer Set with six specialty coffees, plus the ARCA 1.0 l clear, two double-walled porcelain FIKA cups and the STIR stirring spoon with an extra-long handle. You taste the six numbered coffees at home, with breakfast or cake, and vote online for which one you like best. The winners will join the range in 2027.
By the way, the FIKA cups are my favorite cups, and I claim that coffee tastes better from them. The double-walled porcelain retains heat, feels pleasant on the lips and does not get hot on the outside.
All coffees come from the latest harvest, are freshly roasted by Sebastian and are tailored to the ARCA X-tract. Instructions and a link to vote are included in the set.

"She's so cute!"
That's what most people say when they hold the ARCA for the first time. But the impression is deceptive, because the jug holds 1 liter and you can make up to 800 ml of coffee.
And this is how you prepare your perfect coffee:
- Put ground coffee into the filter.
- Fill with hot, not boiling water. (96°C is ideal)
- Stir and loosen lumps.
- Put the lid on and give the flavors time to infuse. (At least 4 minutes, we recommend 12)
- Important: Serve with the filter in the ARCA. This small detail makes the coffee so delicious.
There is no better coffee with rolls or cake.

High quality, durable, dishwasher safe
The patented stainless steel filter has an additional fine-mesh stainless steel sieve inside. The complete filter is made of high-quality stainless steel (18/8, material number SS304). A silicone ring holds the porcelain lid firmly on the filter, This means it won't fall into your freshly brewed coffee.

Easy and quick cleaning
All parts of the ARCA & IONIC X-tract* are dishwasher safe.
To clean the filter, dispose of the coffee grounds in organic household waste or compost and wash them from the outside in under running water.
We clean the filter in the dishwasher once a week. This can also be done with very hot water, a brush and dish soap.
*We decided to make the handle of the porcelain jugs hollow, which means it doesn't get hot and offers a stable construction. The handle has a small hole at the bottom that allows water to occasionally enter and exit. However, this is harmless.

Start with it at breakfast. Good taste and a good feeling - reducing can bring joy.
When less is more. Less effort, better coffee. As simple as that.
Coffee & cake under the open sky – it doesn't get any better than this.

Vanlife, enthusiastic campers, vacationers in the holiday apartment or simply for a picnic in the park...
The durability of the Arca is amazing. In the van we stow them in the packaging provided; for a picnic we wrap them in a bath towel or picnic blanket.
Only a small amount of compost remains from your coffee.
Save trash!

Yes, absolutely. The coffee doesn't stale or become bitter. We have made this experience together with coffee experts. In addition, the filter in the coffee keeps your favourite drink hot for longer. Give the coffee about 4 minutes to release its aroma. After a few more minutes, it will reach the ideal drinking temperature. I find that after around 12 minutes, the coffee is perfect for a cosy breakfast.
We put a lot of effort into the design of our jug to reduce dripping as much as possible. But honestly, we - and no one else - have yet managed to create a perfectly drip-free jug.
However, if you are not too hesitant when pouring and do not fill the jug all the way to the top, you can greatly minimize dripping.
If your filter no longer drains well, you should rinse it hot. We put it in the dishwasher about once a week and select a programme with a high temperature once a month, is it still clogged?
That might happen because the essential oils contained in coffee are not only responsible for its great taste, but can also ruin grinders or in this case clog the X-tract filter. However there is no need to worry, this can be resolved by placing the filter in an oven preheated to around 120°C for around 10 minutes. Then carefully remove it with a pair of tongs or an oven mitt and rinse it immediately with cold water to remove the oils. Leave the filter to cool briefly and then rinse it thoroughly again or put it back in the dishwasher. At this point, it is ready to be used again and as good as new!
The German Coffee Association recommends 60g of coffee per litre of water. This also applies to preparation using the X-Tract method. As a rough measure, we use approx. 6g per heaped spoon at home. This means as a guideline
- 8 spoons for a full arca (add approx. 800ml of water)
- 5 spoons for 1/2 litre of water
- 3 spoons for 300ml of water (one large cup)
If your coffee is too weak and it is not due to the amount of coffee, you have probably brewed the coffee too slowly. This means that the water is flowing too slowly and the coffee is not mixed thoroughly. If the coffee is too strong, simply reduce the amount of coffee powder or choose a milder, fruitier roast with a coarser grind. Experiment a little until you have found your perfect setting.
