The Kalita Wave brings a classic and dynamic brewing technique to the hand-drip pour over method. The dripper features a flat-bottomed brew bed for even extraction, and a filter design that reduces contact between the brewing space and the dripper itself. Kalita Wave allows you to brew your favorite coffee more evenly, which directly contributes to fuller flavor and a more balanced extraction.
YOU WILL NEED
- Coffee (25 grams)
- Kalita Wave
- Hot water
- Glass decanter
HOW TO BREW
1. Place Kalita Wave on top of glass decanter, and set on the scale.
2. Place filter in Kalita Wave.
3. Rinse filter with hot water, pouring directly into middle of filter, pouring on the sides can compromise the shape of the “wave” filter. Rinsing the filter removes any paper taste of the filter and the hot water will preheat the Kalita.
4. Discard rinse water.
5. Grind 25g of coffee and place in center or filter, giving it a gentle tap to flatten coffee bed. This will help to even the water distribution when pouring. Particle size should be like sea salt.
6. Fill kettle with hot water.
7. Start timer and saturate coffee with 20 – 30g of water. Let bloom for 30 seconds. Allowing the coffee to bloom ensures even water dispersion and a delicious cup.
8. Pouring in slow concentric circles, add enough water to raise slurry to about halfway up the side of filter. Continue adding water slowly in stages, submerging the crust as you go and letting the slurry drop a little before adding water to bring it back to the same level.
9. Try to add all water by 2 minutes, 45 seconds. Once you’ve added 400g of water in total, give it a little stir if needed and let drain. You’ve done it right if the coffee bed is flat after draining.
With any pour-over, the water level will greatly affect how your extraction progresses. Keeping the level low will slow down the flow rate and allow you to maintain a more constant temperature. A high water level will drain faster and dissipate heat more quickly. So if you’re making a smaller batch, take care not to add water too quickly—you’ll finish before your target time and end up with under-extracted coffee. If you’re making a larger batch and brewing is going too slowly, you can add water faster to speed things up.
