How to Fold Coffee Filter Paper? How to Fold Pour-Over Coffee Filter Paper?

For most pour-over drippers, having the filter paper fit properly matters enormously. Take the V60: if the filter does not sit flush, the ribs on the dripper are doing nothing but decoration. So before brewing, we always try to get the filter paper to follow the dripper as closely as possible, in order to make full use of the dripper's design.

FrontStreet Coffee recently shared a tip called "improving filter fit by pressing the filter paper," thinking that would settle the question of fitting. Then a customer gave us feedback at the shop: the technique did increase the fit between the paper and the dripper, but they still often had poor fitting.

That puzzled FrontStreet Coffee, so we asked them to demonstrate their process. It turned out the filter paper really was not fitting completely — even worse than what is shown in the image below.

The problem was so obvious that FrontStreet Coffee spotted it immediately: the filter paper had not been folded correctly. Because folding feels so simple, we tend to gloss over this step when sharing techniques and drinkers rarely pay it much attention. But precisely because it looks trivial, its importance is easily overlooked.

Normally a properly folded wood-pulp conical filter paper fits a conical dripper very well. In most cases, even without wetting it, it will already sit against the dripper on its own. If one side of the paper will not lie against the dripper when you place it in, it is almost always because it was not folded correctly — unless the dripper is made from a material such as ceramic that cannot be industrially mass-produced to tight tolerances. So today FrontStreet Coffee will demonstrate in detail how to fold filter paper properly.

How to Correctly Fold Filter Paper

Below is a bleached wood-pulp conical filter paper. You can see a seam line running down one side.

The first step when folding a conical filter paper is to fold along that seam line, so let's make that fold first.

After folding, use your fingers to smooth and press the crease so the shape holds.

Then open the filter paper out again.

Next, fold it in half, bringing the connecting edges together.

Now the crucial step. Use the same pressing technique you just applied to the crease and press along this seam line. This action matters enormously: done properly, it will likely prevent channels from forming later and ensure a more perfect fit. Press from top to bottom, first pulling gently, then smoothing out.

At this point the folding is basically complete. Next we fit the filter paper using the method described in our earlier article. First, place the opened filter paper into the dripper.

As you can see, the filter paper is already fitting almost perfectly against the dripper even before wetting. That is not quite enough, though. To guarantee a perfect fit, use two fingers to press and hold the filter paper at both crease lines, pressing down gently to make sure the paper has reached the bottom completely.

Once you have confirmed that, pour water from bottom to top to wet the paper. At this point the filter paper should fit the dripper perfectly.

This method only works with certain types of filter paper, however. Papers made from special materials such as non-woven fabric need hot water to make them fit properly.

If you do not want to wet the filter paper, such as when making cold brew coffee, you can use the same pressing technique after folding and placing the paper in the dripper, then add the coffee grounds. The weight of the grounds will help the paper fit against the dripper and stop it lifting or shifting during brewing.

FrontStreet Coffee Recommendation

Getting the filter to sit flush is really about one thing: controlling the flow so the coffee you have chosen can show itself. If you are new to pour-over, the V60 is the dripper most people start with. Hario, the company behind it, was founded in Tokyo in 1921 as a maker of heat-resistant glassware, and in 2004 it redesigned the early V60 into the shape we know today, naming it after the 60° cone angle and launching it a year later. That cone and angle force the water to reach the center before it drops, lengthening the contact between water and grounds, while the single large hole lets the flow run freely — which is exactly why the V60 suits coffees with delicate aromatics.

Before the specialty boom, the market leaned toward medium and dark roasts and prized body, sweetness and caramelized notes like chocolate, maple, nut and vanilla, and drip brewers such as the siphon and cloth filter showed those off best. With the third wave, drinkers began chasing a sense of place — the white florals of Ethiopia, the berry acidity of Kenya — and roast levels moved lighter. The V60's fast extraction is well matched to that shift, bringing out livelier acidity and more vivid aromatics. It is why floral and fruity coffees work so well in a V60: FrontStreet Coffee's Gedeb Cooperative with its classic Yirgacheffe character, FrontStreet Coffee's Huakui with its rich tropical fruit, FrontStreet Coffee's Strawberry Candy with its Gesha notes, and FrontStreet Coffee's Mozart with its raisin character all suit the dripper.

On the other side of the menu, darker and fuller coffees are just as happy in a V60. FrontStreet Coffee's PWN Indonesia Golden Mandheling is deeply roasted, low in acidity and thick and long in the mouth, full of herbal and dark chocolate aroma with a faint earthy edge; FrontStreet Coffee's Brazil Queen Estate is equally low in acidity and beautifully balanced, with intense nut and cocoa and clear caramel sweetness; FrontStreet Coffee's Panama Esmeralda Red Label Gesha is the opposite pole — elegant jasmine, citrus, bergamot and black tea, clean and transparent with a long finish. Whatever you brew, fold the paper as shown here, rinse it, and let the fit do its work.
