The short answer: very long. Even without a warmer. The filter inside keeps the coffee warm. We drank our Arca in the morning after about half an hour. Enjoyment until the last sip.

We measured the following temperatures:

• Room temperature 22°, brewing temperature 96°
• After 4 minutes the coffee is ready. Temperature 86°. Very hot, the flavor is still developing.
• after 10 minutes: temperature 78°. I'll wait another 2-3 minutes
• after 20 minutes the temperature is at 70°. Best for me

Have you seen the new warmer?

Fika warmer

Yes absolutely. We leave the filter in. The coffee doesn't linger and definitely doesn't become bitter. We often tried it with trained coffee experts. The coffee in the filter even keeps your favorite drink hotter for a lot longer than if you take it out.

The aromas of the coffee take about 4 minutes to release. Then we give it a few more minutes of rest and time to cool down. I find that after about 12 minutes it has the right temperature and fullness to enjoy.

Perfect for a long breakfast!

I regularly carry the Arca in my backpack when hiking. We gave it to a friend who has been traveling around the world by bike since last year and a few young coffee lovers have also been traveling with the Arca in their van for some time.

The borosilicate glass and also the porcelain jugs are very stable, light and very practical for your perfect coffee at home and on the go.

We like the coffee to be a little stronger, so we use dark roasts with a medium grind. Dark roasts are also often less acidic and have a slightly nuttier aroma. But you can also choose modern, fruity roasts in any grind that you like.

For a whole Arca I take around 50g of coffee (approx. 8 heaped spoonfuls of approx. 6g each) and fill the pot with hot, but not boiling, water to just below the handle, that's approx. 800ml. Just try it out, it varies for me how I like the coffee.

It can be a little milder for breakfast, medium-strong in the afternoon to match the cake and after a good meal we like to have a strong roast. (Espresso roasting or French roast)

The German Coffee Association recommends taking 60g of coffee per liter of water. This also applies to preparation using the X-Tract method. We use a normal spoon as a rough measure; ours at home holds around 6g per heaped spoonful. This means as a guideline:

• 8 spoons for a full Arca (add approx. 800ml water)
• 5 spoons with 1/2 l water
• 3 spoons in 300ml water (a large cup)

If your coffee is too weak and it's not the amount of coffee, you probably brewed the coffee too slowly . It often happens with designer kettles with a thin gooseneck. The water flows too slowly and the coffee is not mixed. Then you have to stir the coffee well.

If the coffee is too strong, simply use a little less coffee powder or a different coffee roast. Try slightly milder and fruity roasts, perhaps with a coarser grind.

Why does coffee become bitter? Often, it's because the water is too hot. With the ARCA, you can perfectly adjust the grind, temperature, and coffee quantity to your favorite brew. The resting time is also crucial: Around four minutes is enough to develop the aromas—but we like to let the coffee rest for 12-13 minutes, as it becomes more pleasant to drink. This prevents the coffee from being further leached, and our fine-mesh filter acts like a membrane that preserves the aroma. Even on a teapot warmer, the coffee retains its aromatic flavor for a surprisingly long time.

If the water is too hot, the coffee will burn and become bitter.

We recommend letting the water cool down a bit after boiling. It depends on the coffee, generally the temperature of the water when pouring should be between 92°C and 96°C. There are also coffees that taste even better when the water temperature is below 90°C.

Unser X-tract Filter hält den Kaffeesatz zurück, lässt aber – im Gegensatz zu Papierfiltern – auch feine Kaffeeöle durch. Das ist erwünscht, denn sie tragen zum vollen Geschmack bei.

Ob diese Öle gesundheitlich relevant sind, ist umstritten. Studien zeigen mögliche Effekte erst bei sehr hohem Kaffeekonsum (mehr als 2 Liter täglich). Als kleine Firma können wir dazu keine eigenen Untersuchungen durchführen – das wäre sehr aufwändig.

Unsere Empfehlung: Weniger, aber besser. Wer empfindlich reagiert oder sich unsicher ist, sollte selbst ausprobieren, was gut tut. Und am wichtigsten für die Bekömmlichkeit bleiben die Bohnenqualität, der Reifegrad und die Röstung.

Yes definitely. Both versions, the Arca in borosilicate glass and the Arca in porcelain, can be kept warm on the warmer with a candle. Just make sure you always have some liquid in the pot.

Please be careful not to overfill the Arca! This can happen especially with the porcelain Arca because you cannot see the filling level from the outside.

Unfortunately, it is a finding that has been true of porcelain and glass pots for over 1000 years. There are countless studies and experiments by designers on the subject, a few drops can hardly be avoided.

The coffee taste is comparably delicious. There are three main features that speak for the Arca X-tract:

The security. You don't have to press down the coffee. This means that no pressure can arise
if, for example, the filter is clogged or not installed correctly. This will prevent accidents.

You can use any grind level with the X-tract method. The way it's best for your favorite coffee. With the French press you are limited to a coarse grind.

Cleaning the Arca X-tract is very easy. You simply tip the coffee grounds into the compost.

This is super easy. Instead of hot water, pour the coffee with cold water. Cold brew coffee takes approximately 10-12 hours to develop. For example, you can leave it in the refrigerator overnight.

We recommend using around 25% more ground coffee than you normally use. Try it. Have fun!

If your filter no longer drains well, you should rinse it with hot water. We put it in the dishwasher about once a week and use a high temperature program once a month.

Still clogged? They're not just at Arca On the one hand, essential oils are responsible for the great taste, but they can also ruin grinders X-tract filter clogged. But it can be easily cleaned because the oils liquefy at around 70°C. The next time you preheat your oven, put the filter in with it. A few minutes should be enough to liquefy the oils. You can wash the hot filter under clean water. Allow to cool and then rinse again or clean in the dishwasher. Then it's like new. If not, please contact me. The contact form is below.
