Always grind the coffee beans just before brewing process. Weight is very important. Make sure to set grind size level just right for best drinking experience.
Our water supply is Poulaphouca Regional. Current water hardness is soft. Water has ppm mineral content around 70ppm CaCO3. We roast and brew for this type of water.
The Statistics & Standards Committee of the Specialty Coffee Association has determined the following standards for the water used to brew specialty coffee. For a superior quality extraction of coffee solids, the brewing water should have these characteristics:
|Odor 1||Clean Fresh / Odor Free|
|Calcium Hardness||50-175 ppm CaCO3||50-175 ppm CaCO3|
|Alkalinity||40 ppm||At or near 40-70 ppm CaCO3|
|pH||7.0||6 – 8|
If you live in Ireland, check you water hardness here and water quality here. For other countries search for water supply for you area.
Always filter chlorine and odours from your water. Cheap jug filters will help you to do that.
If our roast does not taste satisfiable or extraction is harder to achieve, check your ppm in your water and then try to filter or remineralize your water for best possible flavour extraction. See Table for accetable range.
In very hard water area, use bottled water but this is the worst option for the enviroment and it is not a solution. Water filter is more enviromentaly friendly. Bear in mind that this advice is only for coffee brewing. Water low in minerals is catching minerals from your body. Drinking water should be always hight in minerals for effective hydration of our body.

1. Grind the coffee
2. Boil the water.
3. Fit the filter into the upper chamber, make sure it is fully flushed.
4. Place the bottom chamber on the scale and pour in calculated amount of water by ratio.
5. Transfer the bottom chamber to your heat source (gas burner, halogen lamp).
6. Place the upper chamber on top, do not seal!
7. When the water starts to boil, seal the top chamber on the top of the bottom chamber, reduce the heat to low. Look down on the filter making sure it is centered. If it is not centered you will see a lot of bubbles flowing from one side. Push it to the center with stick or spoon.
8. Bubbling on top of the chamber will become agressive with big bubbles. Once the bubbles become smaller, you are ready to brew.
9. Add the grinded coffee to the top chamber with bubbling water, stir untill all coffee is wet. Start the timer.
10. After 30 seconds, give it a gentle stir to break the crust and immerse coffee back to the water.
11. Turn off the heat after another 30 seconds. Once the coffee starts to drawn down, stir gently clockwise and anticlockwise to prevent sticking to the wall. Do not stir too much.
