In anticipation of showcasing some of our best Filter coffees at the London Coffee Festival 2024, Groundstate Coffee Roasters is excited to share a straightforward brewing guide for the Kalita Wave “185.” Known for producing a filter coffee that is notably sweet and well-balanced, the Kalita Wave achieves its distinctive quality through a rapid drip facilitated by its flatbed and uniquely “wavy” filter.

Here's how you can enjoy this exceptional brewing method at home.

Essentials for Brewing:

• Kalita 185 brewer and filters
• A coffee grinder
• Medium grind coffee (texture akin to granulated sugar)
• Filtered or bottled water
• A scale
• A timer (use your smartphone)
• A stirring spoon
• A large mug

Brewing Recipe:

• Coffee: 30g
• Water: 430g (Yield), heated to approximately 95°C
• Ratio: 1:14 (coffee to water)
• Brew time: 2 minutes and 45 seconds

Brewing Steps:

• Preparation: Grind your coffee beans to a medium coarseness. Bring your water to a boil. Pre-wet the Kalita filter to eliminate any paper taste.

• Pre-infusion (Bloom): Position your Kalita brewer atop your mug, placed on the scale. Tare the scale. Start your timer as you add 30g of ground coffee. Pour 80g of hot water over the coffee grounds, ensuring even saturation by stirring. Wait for the coffee to bloom for 45 seconds, signified by the cessation of air bubbles from the slurry.

• The Pour: Add water in 100g increments, using a circular motion to encourage even extraction. Pause for 15 seconds between each addition, aiming for a total water weight of 430g.

• Finishing Up: The total brewing time should be around 2 minutes and 45 seconds. Adjust your grind size for future brews if the time deviates from this.

• Enjoy: Now, it's time to enjoy your freshly brewed coffee. Assess and enjoy!

Adjustments for Taste:

• If the coffee is bitter, try reducing the dose or yield, coarsening the grind, shortening the brew time, or using cooler water.
• If the coffee tastes sour, consider increasing the dose or yield, grinding finer, extending the brew time, or using hotter water.

For those using the smaller Kalita 155 brewer, simply halve all the ingredient measurements but maintain the brewing time as indicated.
