To be honest, Front Street Coffee believes that coffee filter paper can truly be called an extremely versatile tool. Because it's not just for pour-over coffee—it's also used for cold drip coffee, cold brew coffee, espresso, and even some friends use it when making coffee with amoka pot!And at this point, some friends may have questions. The previous ones are easy to understand. But why does the moka pot also need filter paper? What effect does adding filter paper have?What's the use of adding filter paper to a moka pot?Actually, the purposes of adding filter paper are nothing more than two: filtering out coffee grounds, and allowing water to extract more evenly. And the purpose of adding filter paper to a moka pot is the same! It's just that, like with an espresso machine, the effect of the filter paper changes depending on its position.When the filter paper is placed at thefilter basketbottom:Because the hot water in a moka pot is pushed from bottom to top by steam to achieve extraction, when the filter paper is placed at the bottom of the filter basket, it can further disperse the hot water and make the extraction more even. Although that's true in theory, Front Street Coffee's actual testing showed that the effect brought by the filter paper isn't really that significant.And compared to making extraction more even, Front Street Coffee actually prefers its other effect—it makes it easier to knock out the coffee grounds, and cleaning becomes more convenient!Since the water outlet holes at the bottom of the moka pot's filter basket are relatively large, after making moka pot coffee, coffee grounds often get stuck in the holes, making cleaning very troublesome. When we place filter paper at the bottom of the moka pot, the amount of coffee grounds stuck in the holes is greatly reduced, making cleaning more convenient. But whether it's necessary to specifically add filter paper just to reduce cleaning......it's entirely up to personal preference~When the filter paper is placed on top of thecoffee puck:If you frequently make moka pot coffee, it shouldn't be hard to notice that the brewed coffee liquid often contains a small amount of coffee grounds. This is also caused by the relatively large filter holes. When we place filter paper on top of the coffee grounds, it can effectively reduce the presence of coffee grounds in the coffee liquid, because the filter paper's filtration ability is stronger and can effectively block coffee grounds from overflowing, making the coffee taste cleaner.In addition, adding filter paper can also slightly increase the pressure during extraction. Because the passage through which the coffee liquid seeps out becomes smaller, greater pressure is needed to break through, and this can directly lead to an increase in the coffee'sextraction pressure.Although the increase in value isn't much, when our coffee grounds aren't ground finely enough, or when we don't use much coffee powder, this may not be a bad way to increase the extraction rate.In summary, everyone can see that filter paper can also play a role in making moka pot coffee. When placed at the bottom, it can disperse the water flow, make extraction more even, and make cleaning easier; when placed on top of the coffee grounds, it can reduce impurities in the coffee, make the taste cleaner, and slightly increase the extraction pressure.But no matter which effect it is, the impact on the coffee won't be too great. So whether to use filter paper for this small change is entirely up to the individual~ The above content is compiled by CoffeeHunters, a coffee news website.
