Best Coffee Bag Filters for Cold Brew (incl. Users’ Guide)

  • Date: December 11, 2020

In this article, we will give you a roundup review of the best coffee bag filters. But before that, allow us to educate you first. Head over to the users’ guide section for you to understand how we came up with the products in the review section.

The Different Types of Cold Brew Coffee Filters

There are various types of coffee filters in the market. One type might do better than others depending on your specific need. Most determine the type of filters according to their material and shape. We, on the other hand, categorize coffee filters in 3 ways. Aside from the two categories we mentioned previously, there’s another we added – color.

Material

There are two types of coffee bag filters in terms of material – metal and paper filters:

  • Paper filter – Paper filters are made using strands of fiber from different plants such as corn, fast-growing trees, etc. Paper filters are great for having light, clean, and non-oily cold brews. Thickness is very important when choosing paper filters. Buying thin ones are counterproductive. They’re more likely to tear after pouring water in. All paper filters are disposable. You might have to replace them with new ones after using for two or three times.
  • Metal Filter – This kind of filter is out of fine strands of metal that manufacturers meshed. Metal filter does great when it comes to durability. They’re reusable cold brew coffee filter that’s not prone to tearing. They also do a fine job of making concentrated brews. When buying a metal filter, ensure that it’s rust-free and BPA free. A downside with metal filters is that they tend to produce brews that have an oily aftertaste. Furthermore, there might be grounds of coffee powder that goes with the drink.

Shape

In terms of shape, the types of coffee filters are cone, basket, and coffee filter bags:

  • Cone filter – Most cone filters are paper filters. They’re suitable for brewing coffee directly in a decanter or carafe. All you need to do is insert the narrow bottom portion of the carafe then pour coffee powder on its wide uppermost portion. Before buying a cone filter, ensure that it fits on the decanter or carafe that you’ll be using. By the way, a downside with cone filters is that you can’t use them for brewing lots of coffee.
  • Basket filter– Basket coffee has a wider design than cone filters. If you can’t understand, then basket filters look pretty similar to cupcake liners but way thicker and more fibrous. Also, they’re more ideal for brewing coffee for 5-7 people. Basket filters are either paper filters or metal filters. Usually, basket metal filters have a plastic or metal frame. Furthermore, you can opt to use them with automatic brewers.
  • Coffee Bag Filter – Coffee bag filters look like paper pouches. They’re either big or small. Coffee bag filters can be used for coffee storage aside from brewing. Coffee bag filters are ideal if you don’t have a percolator, drip tower, and other types of brewers with you. Coffee bag filters have to be thick. Furthermore, they should have a short strand of thread that’s required for easy use.

Color

This categorization only applies to paper filters. All paper filters can be further classified into two general types – brown and white filters.

  • White paper filters – White paper filters are bleached paper filters. Bleaching is done in two ways – oxygen bleaching and chlorine bleaching. In oxygen bleaching, manufacturers use sodium carbonate. This is a chemical that releases a burst of oxygen on the material that it’s applied to after being exposed to water. This burst of oxygen removes stains and pigmentation. Chlorine bleaching, on the other hand, utilizes the chemical reaction that chlorine causes to remove the brown pigmentation of fibers. If you decide to buy white paper filters, go for those that are oxygen bleached. They’re safer compared to chlorine-bleached filters.
  • Brown paper filters – Brown paper filters are unbleached paper filters. Thus, their color might range from dark brown or light brown depending on the plant fiber that manufacturers used.

Paper Filter vs Metal Filter and White Filter vs Brown Filter

Paper Filter vs Metal Filter

Paper filters are what you need for cold brews that are light, crisp, clean, and non-oily. The fibers that make up paper filters do well in trapping fine particles for coffee powder. Furthermore, they absorb most of the natural oils that coffee has. However, a downside with them is that they suck some of the flavors from the coffee. This results in a cold brew that doesn’t taste very strong.

On the other hand, metal filters are what you need if you love strong cold brews. Metal doesn’t suck the flavor and the natural oil from coffee powder. This results in a darker drink that tastes rich. Still, metal filters have one downside. The resulting brew that you’ll get from them might have a slightly dusty or sandy feel. This comes from the tiny particles of the coffee powder that they failed to filter.

To sum up, go for paper filters if you’re fond of clean and light tasting cold brews. Choose metal filters instead if you love drinks that kick the tongue with bitterness.

White Paper Filter vs Brown Paper Filter

Choosing white filters over brown filters and vice versa doesn’t have much of a difference. Just be sure that you rinse them before brewing coffee. By rinsing, we mean to say that you pour hot water into the brown filter or white filter first before putting the coffee powder in. Rinsing is crucial, especially when using white paper filters. If unrinsed, white paper filters tend to give out a slightly sour cold brew.

Which of The Products Above Do We Recommend?

There’s no bias here. Nevertheless, we really praise EasyColdBrewCoffee Disposable Cold Brew Coffee Filter. There are several reasons why we decided that it’s best. First, it’s made out of natural corn fiber. Thus, it’s health-friendly. The other products also use plant fiber. However, they’re mixed with synthetic materials to reduce production costs. 

Second,  EasyColdBrewCoffee works well for making cold brews from popular brands of coffee powder. This provides a sense of relief since we don’t have to worry about whether or not it’s a coffee filter that’s only suitable for making cold brews with a single specific brand. 

Third, EasyColdBrewCoffee fits under the category of a good coffee bag filter that’s thick and comes with a drawstring that’s quite long. It’s true that it doesn’t seal well. However, the long drawstring makes up for this minor issue. Tying it around the mouth wasn’t hard because holding it was easy.

Finally, we recommend EasyColdBrew Coffee Filter because it’s very versatile. Users who decide to buy it will have an infuser hop bag or spice pack aside from a cold brew coffee filter.
