FREQUENTLY ASKED QUESTIONS

LOCA is a completely new coffee brewing tool not only in Estonia but also in Europe. It has been used in Japan for the last 20 years. Although the coffee taste preferences of Estonians and Japanese are similar, we are still distinguished by some habits related to making coffee and the expectations arising from it. As for the use of LOCA filter, there is an answer and a solution to every question.

"How coarse is the right coffee bean grind for LOCA and where can I get it"?
We recommend the grind level closest to a grain of sugar.  It can be purchased ready-made in our online store and at some LOCA dealers in cafes in Estonia. In other countries, you would need to find a local coffee shop or a roastery to grind it for you. However, the most common practice is grinding yourself with a coffee grinder. It is certain that such coarse grinding is not sold in any grocery stores  and the grinding of the french press is too fine for LOCA for it clogs its pores too quickly.

“Which coffee grinder is best for LOCA and which ones to avoid?
It's not so much about the grinder rather than its ability to grind coarsely and evenly. An ordinary manual coffee grinder is great for this, all you have to do is make sure that its setting also allows coarse grinding. The most common one: tower shaped top-loading electric coffee grinder however leaves a very uneven grind with a lot of dust, which clogs the filter too fast.

"What is the right amount of coffee grounds for LOCA"?
People are different, so there is no single answer. Every cafe and regular user will eventually design their own recipe. We recommend starting with 16g beans per 200ml water. If the coffee is too light, increase the amount of beans. If it's too strong, reduce it.

"My coffee is too cold to drink, what can I do?" If the coffee still leaks in a very fine stream or even drips from the filter, it's time to clean it, the instructions are in the filter package and here.

Common Tips how to maintain a higher coffee temperature:

  • Before making coffee, warm the cup or container with hot water. Do not make coffee directly into a cold cup. Many coffee shops also use this tip to make machine coffee by steam-heating the cups.

  • Place the filter directly into the opening of the cup or jug ​​without the holder. The small U-shaped filter is better suited for this, a V-shaped filter needs a higher cup or jug. This creates a lid on cup that prevents the coffee from cooling down during the brew.

  • The most convenient tip for keeping your coffee hot is to use double-walled glass thermoses or decanters. They have a great ability to keep hot drinks hot and cold drinks cold. In most cases, such cups are available in coffee shops and  regular stores, in different price ranges.

  • Double-walled glass cup is the most effective for making larger quantities of coffee. An induction tray should be used to maintain a higher temperature for a longer period of time - it is important that the coffee pot is suitable for induction.


"I use coarse grinding, but the filter is still clogged, what am I doing wrong?"
It happens often, that people make their first coffees with whatever ground coffee they can find in their home. Which in almost all cases is  too fine - once or twice is enough to significantly slow down (clog) the flow of the filter. Using the right kind of coarse grind later on is no longer helpful. The filter has already been clogged from the too fine grind and only maintenance helps.

There is one cause for clogging that depends not on the grind but on the hardness of the water. The higher the lime and chlorine content in the water, the harder the water. The hardness of water in different regions varies radically. One of the good features of the LOCA filter is that it can remove limescale and chlorine sludge from the coffee water, thus significantly improving the taste of the coffee. However, if the water hardness is very high, it can cause a much more frequent clogging. The easiest and best tip against this is to boil the filter in baking soda water for approx. 15min. Only baking soda can be used for this, 1 tablespoon is enough. Always rinse the filter under warm water afterwards from the soda residue. You can also pre-filter the water using a filter jug ​. You can find more information on that in the user manual or here.

"I burned the filter, but it still didn't get much better ...?" That's probably because you didn't burn it enough. Don't be scared, we recommend you burn it again, boldly this time and for at least 15 minutes. If it turns red, that's fine. Make sure it starts smoking. The only thing that can harm your filter is if you drop it or try to cool it quickly with cold water. Read more about maintenance here.

If you are absolutely sure that the burn has been sufficient and the blockage persists, it is probalby due to the hardness of the water (lime and chlorine residue).

"When do I have to burn the filter and when do i need to boil it, what's the difference?" A good burn always removes the clog if it's caused by the grind dust in the pores. Make sure to rinse the filter well afterwards.

Boiling the filter in water with baking soda  dissolves and removes limescale and chlorine residue that have accumulated in the pores of the filter.

"I live in an apartment, I don't have a gas stove in the room or a gas grill on the balcony, what other opportunities do I have to burn a filter?"
In Japan, almost every household has a gas stove. smart and find workable alternatives when needed.Hiking stoves and gas burners work very well indoors.

Can I try to heat the filter clean in the oven?
Unfortunately, our regular ovens do not provide enough hea.t Too low heat can cause soot clogging, which can be difficult to remove later even by burning.

I use the same bean, but the taste is totally different at home and elsewhere, why?
It's about water, water quality fluctuates dramatically in different regions. Water hardness (lime and chlorine sediment), iron content, sulphides, hydrogen sulphide, salts - all of these affect the taste of the water and therefore the taste of your coffee. Use pre-filtered water or bottled water.

"I like the taste of coffee made with LOCA, but I still want to get my coffee faster and I don't have time for the maintenance. What should i do?  If so, don't leave your filter collect dust in the corner of the cupboard. Do one last maintenance and give to someone who would appreciate it as a gift.

In what terms can i return the LOCA filter to the dealer? 
The requirement for a return is that the filter is unused and clean, the packaging must be intact and clean so that the product can be sold to the next customer. If the conditions are met, you have the legal right to return the product within 14 days of receiving it. 

Used products cannot be returned under the Consumer Protection Act for health and hygiene reasons.
