Behind every cup of pour-over coffee is an arduous process of carefully selected coffee beans, well-grinded roasts and practised pouring. Of course, this delicate process would not be completed without cafe supplies — that includes coffee beans, a coffee grinder, a dripper, some hot water, and most importantly, coffee paper filters.
While not mentioned or heard as often as their supplies counterparts, this inconspicuous piece of paper is responsible for ensuring that every cup of coffee turns out smooth, aromatic and flavourful. And without having to visit a fancy cafe, coffee paper filters can help you to create the perfect brew right in the comfort of your home.
What exactly are coffee filter papers?
As the name suggests, the filters are a piece of paper that aids in your coffee-brewing process. They are often accompanied by the “pour-over” method (also known as the drip method) or fitted into your coffee machines. As the filters are made from paper, they are the most common type of material used in the world of coffee-making.
Coffee paper filters can be found in a myriad of sizes and shapes, and in varying colours as well. From bleached white to soft brown bamboo or even unbleached and natural brown, they all yield the same purpose — that is, to create the perfect cup of coffee.
With paper, the filters are tightly woven to trap coffee oils and sediment that results from the coffee brewing process. Coffee paper filters are also highly absorbent, which makes them the perfect solution to catch any other unwanted particles found during the brewing process.
Through an intricate filtering process, your coffee beans will be infused with the right minerals and acids to create a perfectly balanced cup of coffee. But that’s not all, by filtering your coffee beans properly, you’re able to create a cleaner, lighter and brighter taste in your coffee. With lesser unwanted condiments, your coffee beans would naturally take in more minerals to create that crispy mouthfeel too.
Types of coffee filter papers
Coffee paper filters can be found in a myriad of sizes and shapes, and in varying colours as well. For colours, they range from bleached white to soft brown bamboo or even unbleached and natural brown, but all yield the same purpose — that is, to create the perfect cup of coffee.
For shapes, there are generally three types to keep in mind — Cone, basket and disc filters. Many of us would be familiar with cone filters by now. By nature of its name, cone paper filters come in the form of cone shapes. They have a wide opening at the top that gradually reduces to a closed tip at the end. As one of the easily accessible coffee paper filters, they can be seen used commonly in home drip coffeemakers or used by hand in pour-over coffees.
For basket paper filters, they mimic the likeness of a woven basket with curly cues at the side, along with a flat base. They can also be found commonly in home drip coffeemakers but it does have a drawback. If you have uneven coffee grounds, a basket paper filter might result in an under-extracted coffee or even one that tastes bitter.
The third type is disc paper filters. As the name describes, a disc filter comes in a circular shape with a hole in the middle of the filter. Due to their flat structure, disc coffee filters are typically used in coffee makers and not in pour-over methods. But there’s a plus side to this. With disc filters, you’re able to experiment with medium to coarse coffee grinds as the filters allow you a longer extraction time compared to cone or basket filters.
Coffee Filter Paper Sizes
When it comes to the sizes of coffee paper filters, it is crucial that you select a filter based on the number of cups you’d like to serve. As each filter is sized by a number, it will help you determine how many cups you can brew with a single filter.
For instance, with # the number of cone filters, you’re able to brew the following amount of coffee cups with your coffeemakers or with the pour-over method.
- 1 filter: 1 cup
- 2 filters: 2-6 cups from coffeemakers and 1-2 cups from pour-over
- 4 filters: 8-10 cups from coffeemakers and pour-over
- 6 filters: more than 10 cups from coffeemakers
However, for basket coffee filters, you’ll want to keep in mind that they usually come in a standard size. In other words, unlike cone filters, a single basket filter allows you to brew 6 standard cups of coffee. If you’d like to make less than 6 cups, you may opt for a junior basket filter.
Other Benefits of Coffee Filter Papers
Apart from producing an incredible cup of coffee, coffee paper filters do so much more for coffee drinkers. As the filters are for single-use only, it means you need not spend time cleaning or washing the filters. After brewing, simply discard the filter together with your coffee grounds. However, with single-use, it can be wasteful and not sustainable. For this, you can choose to opt for unbleached and bamboo paper filters, which are more eco-friendly choices.
And for the health-conscious coffee drinkers out there, using coffee paper filters is a great way to reduce your cholesterol level. By filtering out most coffee oils and coffee grounds, there will be a lesser amount of bile acids and neutral sterols. So you’ll still be able to enjoy your coffee without worrying about your cholesterol intake.
While coffee filter papers have their upsides, it does have some downside too. But not to worry and this may go unnoticed if you’re not particular about the papery taste of your coffee. And there’s also an easy solution for this.
Before using your filter, you’ll want to always give them a rinse before you start brewing. Or, before placing your coffee grounds into the filter, drizzle the filter with water and flush it out. With the pre-rinse, you’re able to wash away this distracting flavour or minimise any papery taste.
How to use coffee filter papers?
If you’re new to the “pour-over” method or it is your first time trying out a paper filter, not to worry because we’ve got you covered with these few simple steps:
- Give your paper filter a pre-rinse and place it into a cup of your choice
