Where does the coffee filter come from?

Melitta makes coffee a pleasure - and has been for over 100 years. The coffee filter and its holder were patented in 1907 by Melitta Bentz from Dresden. Before that, blotting paper or cotton rags that had been cut to size were used as filters. Read more about the history of coffee filter bags here.

Paper filter or permanent filter?

Most people use paper filters. Paper filters are cheap, easy to use and most coffee drinkers find them more hygienic than permanent filters. In reality, permanent filters are no less hygienic than paper filters - after all, they are cleaned regularly and fully automatic coffee machines also work with permanent metal filters.
Permanent filters have the advantage that - as the name suggests - they can be used permanently and there are therefore no expenses for paper filters. To do this, however, the permanent filter must be rinsed off after each use and thoroughly cleaned once a week. Permanent filter manufacturers advertise that there is no glue washout or paper taste, but paper filter users report an unpleasant taste caused by the permanent metal filter.
The waste reduction could speak for the permanent filter. But since almost all paper filters are biodegradable and thus organic waste, this argument is hardly relevant.
Many coffee machines come with a permanent filter - mostly made of plastic. Just give it a try if you run out of paper filters and decide for yourself what you like better!

The porcelain filter

The porcelain filter is practically a complete coffee machine, because the ceramic filter is operated manually: it is placed on a coffee cup, equipped with a coffee filter and coffee powder and hot water is poured over it. This saves you electricity and purchase costs, because the ceramic filter is a little cheaper than a simple filter coffee machine at ten to twenty euros. You can also use it to brew several cups of coffee, provided you have a jug that holds this number of cups and on which the porcelain filter fits.

The sizes of the coffee filter

Coffee filter bags come in many different sizes, either z.B. with "1 x 4 " or "4 " or "101 ". The designation "1 x 4 " and "4 " mean the same size, but the 100 series is a size of its own. Thus, the size 102 does not match 1 x 2! The majority of filter coffee machines use size 1 x 4. Read here where this marking comes from and what else is worth knowing about the sizes.

The right coffee powder for the coffee filter

For a perfectly aromatic coffee, not only the coffee filter but also the coffee powder is crucial. Two components are important here: the coffee blend and the grinding.

The coffee blend

The mixture is made up of different components: the coffee bean, the country of origin and the roast.

The coffee bean

In Europe, more coffee is made from Arabica coffee beans than Robusta coffee beans
drank. Worldwide, 70% Arabica and only 30% Robusta plants are planted. Arabica coffee beans mostly come from Central or South America, while Robusta comes from Asia. The beans differ in taste and caffeine content: Robusta with 2 to 4.5 percent can have more than twice as high caffeine content as the Arabica coffee bean with 1.1 to 1.7 percent. In addition, Robusta tastes bitter and earthier, whereas the Arabica coffee bean usually tastes a bit more fruity.

Country of origin

Few coffee buyers pay attention to the country of origin of their coffee. The difference between coffee from Costa Rica and Mexico is also really difficult to tell. After all, it's the same type of coffee. However, the height at which the coffee grew affects the taste: the higher the coffee plant grows, the slower it grows and the more caffeine it contains at the time of harvest.
Even the plants that surround the coffee plant have an impact on the taste. Unfortunately, this cannot be taken from the pack in the supermarket.

The roast

The difference in roasting can be tasted even for non-coffee drinkers: the more the coffee beans are roasted, the darker they are and the more aromatic but also the more bitter the coffee tastes. Most coffee drinkers prefer a medium roast.

The grind

Not only the coffee beans are decisive for the taste of coffee, but also the grinding of these coffee beans. The right degree of grinding depends on how long the water comes into contact with the powder. If it comes into contact with the coffee powder for only 20 to 30 seconds, as it is e.g.B. This is the case with the espresso machine, the coffee powder must be ground very finely so that the water can absorb sufficient aroma in the short time. A medium grind (4 to 5) is recommended for the filter coffee machine, as the coffee powder is in contact with water for about three minutes.

Tips & Tricks Moisten the coffee filter before use. This way it fits better into the holder and is guaranteed not to taste like paper.
