Filters play a vital role in the preparation of a good cup of coffee. They come in different materials and shapes, which can affect the taste.
Coffee filters are often made of disposable paper. Paper filters are cost-effective and can be unbleached, so they are processed easier and become more environmentally friendly.
Metal filters are more durable and only need a quick wash, which is the reason they will cost a bit more. However, unlike the paper filters, the metal allows the oils from the beans to flow through to the pot, which results in the stronger, bitter taste coffee lovers crave for.
Cloth filters are not as popular, but they promise you a super bold brew. Even though they can last up to three or four months, they need to be replaced as often as possible. Due to the natural fabrics they are made of, coffee grounds have a higher chance of slipping through.
There are two kinds of shapes regarding filters - cone or flat bottom. Coned shaped filters are for people that prefer a stronger taste and aroma. Flat bottom ones will give you a weaker strength since the coffee grounds cannot be completely covered by the water, so it just streams in the middle.
