Product Information

In contrast, loose-knit paper filters are easier to use because the drawdown is faster, but the end result means less clarity and vibrancy in the cup. According to Hiro and Gabriel, people often don’t think enough about which paper filter to use when brewing pour over coffee. Understanding how they are made, which materials used in their manufacture, and how their composition affects extraction can all inform the brewing process. will have MOQ requests. The box is 1000pc and the polybag is 20000pc, these need to be made for one time, but can be used separately. Once the fibres have been press-heated into a filter, the manufacturer will then decide whether or not to bleach them. The study found that for lighter roasts, flat bottom brewers yielded more sweet and floral notes, while conical brewers brought out slightly heavier and berry-like flavours.

Hiro uses a different recipe: he says to start with 16g to 19g of medium-coarse coffee, and to aim for a total brew weight of 250ml to 300ml. The water temperature should be between 93ºC to 95ºC. For those who don’t own a temperature-controlled kettle, Hiro suggests leaving the kettle at room temperature for 5 minutes after boiling. Consider what your filter paper is made of, for starters. A range of raw materials are used to manufacture filter papers, from mineral fibre pulps and fibre crops to softwoods and hardwoods. Fibre length typically determines the porosity of the filter paper, which subsequently has an effect on the compounds and oils that are extracted into the final cup. Bamboo and abaca (also known as Manila hemp) have the longest fibres of all of the common raw materials used to manufacture filter paper, and are consequently more porous (meaning more oils make their way into your cup). In contrast, eucalyptus pulp has the shortest fibres, and is the least porous of all the pulps used to manufacture filter paper.You may have a preference based on whether you are concerned about the planet, but in the end, they should all break down and biodegrade as they are made from paper. The Hario V60 and the Chemex are two of the most popular conical brewers available today, while the Kalita Wave and the Fellow Stagg X are common flat bottom brewers. Each uses their own corresponding shape of filter paper. We have a guide on how to choose the best filter for your coffee maker, as well as information about the size you will need. For most cone papers, a general rule is:

While there’s already no shortage of things to consider when calibrating your brew recipe – including grind size, dose, and brew time – thinking about your filter papers can help you fine-tune the resulting cup profile. While there is no research to suggest there is a difference in flavour between oxygen and chlorine-bleached filters, studies do indicate notable differences between unbleached papers and those bleached with oxygen. Most importantly, unbleached filters tend to give the final cup a “papery” flavour and aroma. The SCA and UC Davis study explains that the differences in shape between the two brewers influences the flow of water throughout extraction. As flow rate changes, it alters what scientists refer to as “mass transfer” – the speed at which water moves through the ground coffee. It’s easy enough to tell if your filters have been bleached during manufacturing; if they’re brown or have a distinct “natural” colour to them, then they’re unbleached. If they’re a uniform white, this indicates that either chlorine or oxygen have been used to bleach the fibres.CLEAN and HEALTH】The coffee color is not bleached and no chemical agents are added to ensure health and hygiene. EASY to USE and CLEAN】This product is a disposable cone-shaped coffee filters paper, easy to operate, no need to clean after use. When pre-wetting his filter, Hiro uses a spoon to press the paper down into the dripper – this, he says, helps it to fit snugly into the brewing chamber. Making sure your filters fit your brewing device should be a priority when making your choice. There are two main styles of pour over brewers – conical and flat bottom – and each have their own unique characteristics that affect extraction.
