The Correct Way to Use Coffee Filter Paper! What's the Difference Between Wetting and Not Wetting Filter Paper Before Pour-Over Coffee?

Attentive readers may have noticed that FrontStreet Coffee changes not only the brewing parameters but also the procedure itself depending on the coffee. Wetting the filter paper is a perfect example.

For hot pour-over, FrontStreet Coffee always rinses the filter paper before adding grounds and starting the brew. But for iced pour-over, we skip that step entirely — grounds go straight into the dry filter. Naturally, this raises the question: why wet the paper sometimes and not others?

The answer is simple: the difference barely matters! Let's quickly revisit the three traditional reasons for rinsing the paper — removing paper taste, preheating the dripper, and making the paper adhere to the walls.

Modern gear has quietly retired most of those reasons. Take paper taste: years ago, filters had a noticeable papery flavor that had to be rinsed away in hot water, or it would leach into the cup. But with advances in manufacturing, flavor-neutral filter papers have been the norm for a long time now — so there's simply nothing left to rinse away.

Preheating comes down to the dripper's material. Ceramic and glass pull a lot of heat out of the brew water, so skipping the preheat costs you extraction efficiency. But FrontStreet Coffee brews with resin drippers, which barely absorb heat at all, so there's nothing to worry about there. If anything, the server and the mug are the vessels that actually need preheating.

That leaves adhesion. The ridges (flow ribs) on every dripper exist to hold sections of the filter paper away from the wall, giving the grounds extra escape channels for air and improving flow rate. For that to work, the paper needs to sit snugly against the cup — but water isn't the only way to get there. When FrontStreet Coffee brews iced pour-over, we simply use the dry grounds themselves to "press" the paper into place.

The method couldn't be simpler: fold the paper into the dripper, press it down with your hand, then pour in the grounds. Held in place by their own weight, the paper locks down and settles against the walls as the brew progresses. So wetting or not wetting the filter paper makes no meaningful difference to the final cup.

The reason FrontStreet Coffee still rinses the paper for hot brews is mainly a side benefit: it preheats the server at the same time, so the finished coffee doesn't lose heat to a cold vessel. For iced coffee, that concern vanishes — and so does the rinsing step.

FrontStreet Coffee Recommendation

Great pour-over starts with the right beans for your dripper. The cone-and-60° design funnels each pour through the center for full extraction, and the single large outlet puts flow rate entirely in the brewer's hands — perfect for the clean, aromatic style these FrontStreet Coffee beans were roasted for:
