Brewing a great cup of coffee depends on a number of things such as the quality of the coffee bean, the quality of the water being used, the type of brewing being done, and the grind of the coffee.
Of course filters play an important role in managing the balance between over and under brewing your coffee. Not only do they keep the grind out of your cup, but they also control how fast the water passes over the grinds.
Paper filters are the most common, but many people are also using metal varieties. Paper filters are quite good. However they can absorb some of the coffee flavor, and some people claim they can taste the paper in the final coffee.
Metal filters are normally made from stainless steel or gold plated mesh. They have very fine weave and filter out the coffee grinds very well. They also do not alter the taste of the coffee at all. Metal filters are also more environmentally friendly than the paper alternative.
Whichever you choose, be sure to buy decent quality. Cheap filters often clog or not allow the coffee to brew properly. A decent quality metal filter will last years and save money in the end.
Brewing a cup of coffee is not that hard. Brewing a great cup takes a little more understanding, but isn’t any harder. Start with fresh beans and good clean water and then match your brewing style to the proper grind and then mess around with the exact proportions and pretty soon you’ll be brewing killer coffee every time.
