What do you need?
- Coffee Brewer (dripper)
- Paper filter
- 21g (Approx. 3 Tbsp) of Coffee
- 350ml of hot filtered water immediately after boiling (about 94° C)
- Scale (optional)
- Mug or server
Step 1 - Rinse and Preheat:
Add a filter to the coffee dripper and place it on top of your mug or server. Rinse the filter with hot water to remove any papery flavors; this will also pre-heat both your vessel and brewer. Discard this water before proceeding.
Step 2 - Grind the coffee or add the ground coffee:
If you are grinding your fresh coffee beans, set your coffee grinder to a medium grind. Based on your results, the milling setting is one of the key variables you can adjust for future extractions.
Our recipe uses 14.3 grams of water for each gram of coffee; so as long as your Brewer is big enough, you can scale up from there.
Step 3 - Tare (zero out) your scale.
- Start a timer and slowly pour the filtered water at a temperature of about 94 degrees Celsius (or let the water cool for about 20 seconds after boiling), equivalent to about twice the weight of the coffee (42g of water).
- Make sure to cover all of the grounds with water, reaching any spots that are still dry after initial hydration. You will notice bubbles - this is the carbon dioxide that comes out of the coffee beans.
- Wait 30 seconds.
Step 4 - Pour Continuously:
Grab your hot water, making sure the temperature is close to 94 degrees Celsius. Start pouring your water in a slow circular motion. Pour about half of your water to get started, then let the water level drop a little and refill.
This is the part of doing a spill that takes a little practice, because you don't want all your water to drip through too fast or too slowly. If the water level starts to get close to the top of your brewer while pouring, slow it down or allow a brief pause to prevent overflow.
Step 5 - Remove brewer and enjoy:
Keep an eye on your coffee as the water drips through, and when you start to see the coffee grounds appear, remove the brewer from your mug or server and place it in the sink or on another cup to drain (the last few drops of water can be a little bitter).
The timer should read between 2:30 to 3:30 minutes. If your water is taking too much time to drip through, try to either pour faster or set your grinder a little coarser next time. If it’s going through too quickly, pour slower or grind finer.
Enjoy your coffee!
