Pour-over is the method that gets out of the way and lets the coffee speak. Gravity does the work. Hot water moves through a bed of grounds and a paper filter, carrying dissolved compounds into the cup below. No pressure, no immersion, no mechanical intervention - just a slow, controlled pour and whatever the bean has to offer. The result is the cleanest, brightest, most transparent cup in home brewing. For decaf, that transparency is both an opportunity and a test.

​
What is pour-over and how does it differ from drip?

Pour-over and drip filter brewing are structurally similar - both use paper filters and gravity - but pour-over gives you direct control over every variable. You choose where the water lands, how fast it flows, and when to pause. Automatic drip machines make those decisions for you, often inconsistently. The most common pour-over devices are the Hario V60, the Chemex, and the Kalita Wave. Each has slightly different geometry and filter thickness, which affects flow rate and brew time, but the core technique is the same across all three.

​
What grind size should you use?

For a V60, use a medium to medium-coarse grind - close to drip medium but slightly coarser to account for the faster drain rate of the conical design. For a Chemex, go slightly coarser again. The Chemex uses a thicker bonded paper filter that slows flow, so a finer grind would choke the brew and extend the time into over-extraction territory. Colipse offers a drip medium grind that works well as a starting point for most pour-over devices. If you are using a Chemex specifically and grinding at home, step one notch coarser than your normal drip setting.

​
What ratio and temperature should you use?

Ratio: 1:15 to 1:17 (coffee to water by weight). A common starting point is 25g of coffee to 375-425ml of water. Water temperature: 90-96°C. The lower end of that range suits lighter roasts; the upper end is more forgiving with medium and dark roasts. For decaf specifically, 91-93°C is a reasonable default. Decaf beans have had some structural changes from the Swiss Water® Process and can be slightly more porous, which means they extract a touch faster than their caffeinated counterparts. Starting slightly cooler gives you more control.

​
Why is the bloom important - and does decaf bloom differently?

The bloom is a short pre-infusion step before the main pour. You add roughly twice the coffee weight in water (about 50ml for 25g of coffee), stir or swirl gently, and wait 30-45 seconds before continuing. Fresh-roasted coffee releases a significant amount of CO2 when hot water hits it - you will see it bubble and dome. That CO2 outgassing can create uneven extraction if you skip the bloom, because the gas pushes water away from parts of the coffee bed. Decaf blooms less vigorously. The Swiss Water® Process and the roasting that follows it dissipate more CO2 than a standard caffeinated roast. You may see only a modest amount of bubbling. The bloom is still worth doing - it evens out the wetting of the grounds and sets up a more consistent extraction - but do not judge your decaf as stale just because it does not dome dramatically.

​
How do you pour?

After the bloom, continue in 3-4 stages:
  1. First pour: Bring the water level up to about 150ml total (including bloom water). Pour in slow, concentric circles starting from the center and moving outward. Avoid pouring directly on the filter walls.
  2. Second and third pours: As the water level drops to just above the grounds, add the next pour. Maintain a steady, slow spiral. The goal is to keep the water level consistent rather than letting it drain completely between pours.
  3. Total brew time: Aim for 3-4 minutes from first water contact to final drip. Shorter than 3 minutes usually means the grind is too coarse or the pour was too fast. Longer than 4 minutes suggests the grind is too fine or the filter is clogged.
Rinse your filter first. Before adding coffee, place the filter in the device and pour hot water through it into your cup or server. This removes the paper taste and preheats the brewer. Discard that water before adding grounds.

​
How does decaf shine in pour-over specifically?

Pour-over is a clarity method. It removes the oils, filters out the fine particles, and produces a cup where the origin character of the bean - its acidity, sweetness, and any fruit or floral notes - is more audible than in immersion methods. Swiss Water® Process decaf, when sourced from high-altitude farms, retains the complexity that makes origin character worth showcasing. Colipse sources from JUMARP-certified high-altitude farms in Peru, where the elevation produces beans with genuine brightness and sweetness. Those qualities are muted in a French press. They come through in a pour-over. The paper filter also traps diterpenes (cafestol and kahweol), making pour-over the lowest-cholesterol-impact brew method. For anyone who drinks multiple cups a day, that distinction matters more than it might for an occasional drinker.

​
Which Colipse Decaf Coffee product works best with pour-over?

The Medium Roast Decaf is the right choice here. The lighter roast preserves more of the bean’s origin character - the acidity and sweetness that pour-over is designed to reveal. A dark roast through pour-over can taste flat or one-dimensional because the roast has already done the flavor work that the method is trying to uncover. Medium roast lets the method do what it is built for.
