How to buy coffee filters?

Bleached filter paper vs unbleached filter paper

Coffee filter paper is mostly made of wood, and most of the pulp color after wood cooking is brown, which can be turned white after several bleaching processes.

The difference between bleached and unbleached coffee filter paper is as follows:

1, bleaching: refers to the coffee filter paper after bleaching treatment, filter paper looks more white.

2, no bleaching: refers to coffee filter paper has not been bleached, filter paper looks close to light brown.

Simply put, filter paper is generally used to drip coffee, grind coffee beans, coffee powder, extract coffee liquid filter into the cup, filter paper can also filter the fat of coffee, get clean coffee solution, good filter paper can filter out impurities, coffee drink more alcohol, aroma is more obvious.

Advantages: high convenience, disposable, can also change the brand; rushed out of the taste is relatively clean; impurities less miscellaneous smell.

Disadvantages: less environmentally friendly use of paper; non-bleached paper will have paper smell; oil will be filtered out, resulting in coffee taste without grease feeling, get a cleaner taste. Daily brewing| Share experiences, make a cup of coffee with balanced taste and fat extraction method

While we've been comparing bleached and unbleached coffee filters, that's not the only difference between filter papers. The quality of the filter paper is also important to keep the coffee apparatus clean and good filtration flow rate. It sounds easy to say here, but the impact is really big.

In addition, be sure to select filter paper that fits the cup size and pay attention to thickness and density-too thin and thin filter paper will allow water to flow through faster, while too thick and dense filter paper will filter out more coffee fat (such as Chemex).

Does that mean you have to rinse the filter paper? Wash? Or not? This is a problem…

For beginners, a set of practices is to fold filter paper, wash filter paper, warm filter cup, anyway, just do it, but some Japanese old drivers do not wash filter paper, so I can't imagine "why must we wash filter paper?" Doubt.

It doesn't matter, let's analyze it carefully below:

1. Consideration of removing pulp taste

In fact, the above description of bleaching non-bleaching filter paper, pulp filter paper because it has not been rinsed, wood pulp flavor is still very strong, so wash filter paper. The bleaching filter paper, residual paper taste and bleaching taste are adapted to the brand, and the high-quality filter paper can indeed be processed to be very clean, and there is little difference between washing and not washing.

2. Consideration of fit with filter cup

Washing the filter paper helps improve the fit of the filter cup, helps to fit the rib design of the filter cup and the brewing principle, but in most cases, the fit of the filter paper and the filter cup is worse than that of the preheated pre-washing.

3. Consideration of filter paper absorbing coffee oil and initial extract

If the filter paper is not rinsed, the filter paper will absorb some of the water and oil during steaming, and bring out some suspicious odors.

Therefore, for the sake of the integrity of the extraction flavor, it is more appropriate to rinse the filter paper.

[Common filter parameters]

11 kinds of conical filter paper introduction

Metal coffee filter

Metal filter, save less environmentally friendly filter paper as long as it is cleaned after use and can be reused, made of stainless steel is also durable and strong.

Suggestion: After use, use a clean toothbrush to brush gently, and remove the oil with baking soda powder, so as not to affect the taste of the next brewing. The metal coffee filter allows the oil to be extracted, and the taste will be thicker and closer to the original taste of coffee beans. In blind tests, you can also feel the difference with filter paper.

Advantages: more environmentally friendly, through washing and reuse; more able to drink the original taste of coffee, thick taste.

Disadvantages: fine powder is easy to cause excessive extraction resulting in excessive bitterness; fine powder will pass through the filter into the coffee, the taste may have a residue feeling.

Coffee filter cloth

Usually used in flannel filter cloth, Siphon siphon type, more troublesome is cleaning and preservation, if not really clean the oil on the filter cloth, over time will affect the taste, after washing also need to soak in water to store in the refrigerator, can not be used many times a day, is a more troublesome point. The coffee flavor is between metal and filter paper, balancing the advantages of both.

Suggestion: filter cloth cleaning and preservation needs to be done, otherwise there may be rag smell, it is recommended to use baking soda powder to clean when available, and flannel filter cloth permeability, heat preservation is better, brewed coffee aroma and taste are called saturated rich.

Advantages: Fiber is thicker than filter paper, oil will adhere to make water and coffee have a longer contact fusion.

Disadvantages: It is difficult to preserve, it takes time and effort; it requires more practice and skills.

Comparison of three filtering methods

All three have their own advantages and disadvantages. Filter paper is only a small part of coffee brewing, and there are many factors affecting the taste of coffee. The taste of each filter paper is different due to the flow rate. You can try several kinds. Friends who like coffee flavor can add more reference filter cloth and metal filter, which can retain oil and original flavor. Friends who like clean and refreshing taste can use filter paper.

It's not hard to make a cup of drip coffee, but it's not easy to make a good cup of drip coffee. Like espresso coffee, many variables need to be grasped. Filter paper is a variable, and there are also variables such as water quality, water injection amount, drip rate, coffee grinding degree, etc. You need to grasp each variable and adjust it constantly to finally find the kind of experience that your taste buds need.

Our front street cafe still prefer this KONO coffee filter paper drip filter hand-washed filter paper, as long as it is conical filter cup are applicable oh, whether it is harioV60 filter cup or KONO filter cup can be used, and Japan imported KONO filter paper medium texture, not thin nor thick, water filtration medium strong, water injection and filter cup fit is very ideal.

Ears coffee

Finally, a filter paper is introduced, which is more convenient, that is, hanging ears.

The coffee powder used in ear-hanging coffee is ground from freshly roasted coffee beans. The ear-hanging coffee can retain the original flavor of coffee to the maximum extent, usually by hot extraction.

Because there will be coffee grounds, so there must be filter bags!

//

Filter bag material

This material is called degradable nonwoven filter bag

The ear lining is a filter layer with mesh holes that homogenize the rate of coffee flow.

Hot water percolates through the coffee powder, extracting its essence and oil, and finally the coffee liquid seeps evenly through the filter holes.

Grinding degree: According to this design, the grinding degree cannot be too fine, close to the size of granulated sugar.

There is also a coffee bag on the market, similar to a tea bag. It is freshly roasted coffee beans after grinding, according to the cup amount packaged in disposable follicle bags, made into convenient coffee bags, materials like tea bags, most of which are non-woven fabrics, gauze and the like, this material needs to be soaked.
