This method of coffee brewing produces one of the best cups we've ever enjoyed--flavorful, clean, with great fragrance. No electric brewer required. Gravity does all the work. The determining factors are freshness and quality of the coffee, grind, water temperature, time, and the filter itself.
Conical filters, the type generally used for pour-over brewers require a medium grind. The grind should slow down the rate of flow sufficiently to allow good infusion and extraction, extracting out the most flavor, but without clogging up the filter.
Use two tablespoons (approx. 14 gm) of coffee per eight ounces of water. Certainly this ratio can be adjusted to your preference.
- Bring freshly drawn, filtered cold water to a boil (about twice the amount needed for brewing).
- Insert paper filter into cone holder and "rinse" the filter with some of the boiled water. Pre-wetting the paper filter ensures that coffee oils wont creep up and escape during the brewing, and removes some "papery" taste. However, most quality coffee filters manufactured these days do not have a bleachy taste. Oxygenated filters are great too. Dump out any remaining water, and set the cone onto coffee cup, mug or carafe.
- Grind the coffee with a medium grind, and transfer into filter. Two heaping tablespoons makes a great large mug of coffee. Six-seven tablespoons for 1 litre.
- After the water boils, allow it to cool for about 30 seconds before starting the brew. Pour a small amount of water over the coffee--just enough to wet all the grounds. Freshly roasted coffee will "bloom" like a chocolate souffle as carbon dioxide is released from the coffee. Allow the water from this pre-wetting step to absorb into the coffee for about 15-20 seconds.
- Now slowly add more water, but just to the level of the coffee. Always try to keep the brewing coffee "low in cone." Carefully add more water, slightly increasing the depth as it brews. This should ensure that all the coffee is contributing to a great cup. For a single serving, keep the brewing coffee as low as possible in the cone to maximize the brew time. Avoid pouring water directly onto the paper filter. As the coffee passes through the filter, slowly add the remaining water using a gentle circular motion.
