What Is Filter Coffee? What Makes It Different From Others

There are a variety of ways to make a cup of coffee; however, the simplest principle for Filter Coffee means hot water will drain, or 'filter', through ground coffee and into a container. Based on the specific recipe or method you use, filter coffee can be light and simple to dark and milky.

What Is Filter Coffee?

So, what is filter coffee exactly? It is coffee made by allowing hot water to pass through ground coffee held in a filter. The filter separates the grounds from the brewed liquid.

Unlike instant coffee, it is prepared from ground beans. Unlike espresso, it does not depend on high pressure to push water through the grounds. Water moves through the coffee gradually.

The term "filter" covers several methods, including pour-over, automatic drip coffee, etc., which we will cover in this blog.

History of Filter Coffee

It all started with a practical issue that arose in producing coffee without consuming grounds. Simple filters were made from cloth and metal, made by people wanting brewed coffee without consuming grounds and then progressed to more complex equipment. The emergence of paper filters in the early 20th century made producing clean cups of coffee considerably more straightforward.

Automatic drip machines later brought filtered brewing into homes and offices. Meanwhile, different coffee cultures developed their own methods.

With time evolving, Vietnam's Robusta and Arabica coffee have become one of the most widely used and finest coffees worldwide. Today, Arabica and Robusta species dominate the entire world coffee market, and you can buy those authentic Vietnamese coffees here.

Types of Filter Coffee

Filter coffee is not one single brewing style. Different equipment and extraction techniques change the final cup of filter coffee.

Vietnamese Phin Filter Coffee

A Vietnamese phin filter is a small metal coffee filter used to brew Vietnamese coffee. It is an important part of Vietnamese coffee culture. It sits directly on your cup, slowly dripping hot water through finely ground coffee, producing a strong, rich, concentrated brew.

Pour-Over Filter Coffee

Pour-over is a manual method where hot water is poured over coffee grounds placed in a filter. The water travels through the grounds and drips into a cup or carafe. With this brewing method, the brewer has more control over time and the taste of the coffee.

Automatic Drip Filter Coffee

Automatic Drip Filter Coffee is an electrical brewing method using a machine where hot water is placed and automatically heated, and then passed through ground coffee and a filter. The brewed coffee collects in a pot, producing a smooth, consistent cup with minimal manual effort. It's great for making multiple cups of coffee.

French Press Filter Coffee

A French Press uses immersion. Grounds steep in hot water before a mesh plunger separates them. Its mesh filter leaves more oils and fine particles in the cup. Technically, it is an immersion method rather than traditional filter brewing.

AeroPress Filter Coffee

The AeroPress combines immersion and pressure. It is compact and versatile, allowing users to experiment with brewing time, grind size, and recipes. It is also practical for travel.

Vacuum / Siphon Filter Coffee

Vacuum or siphon brewing uses changes in pressure and temperature to move water between chambers. As it requires more equipment, it is not commonly used for making filter coffee, but those who are passionate sometimes use this to produce a clean, aromatic cup.

Filter Coffee vs Other Coffee Types

Let's take a look at the difference between filter coffee and other popular coffee types.

• Filter coffee vs espresso: Espresso, it uses a lot of pressure to push the hot water through the finely ground coffee sitting underneath, and this extracts a shot of concentrated coffee rapidly (likely under 1 minute). With filter brewing using gravity, the coffee takes much longer to drip through and is much more fragrant with more flavors.

• Filter coffee vs instant coffee: Filter Coffee is made from beans that are ground, then brewed together. Instant Coffee is coffee that is already prepared, brewed, and dehydrated so you can make coffee instantly.

• Filter coffee vs drip coffee: Drip coffee is a type of filter coffee. "Drip coffee" often refers specifically to automatic drip machines.

How to Choose Coffee Beans for Filter Coffee?

How to Make Filter Coffee at Home

There is no real need for fancy equipment in order to do home-filtered coffee; the one very important thing is fresh coffee beans, correct grind, and sufficient time.

Ingredients & Euipments

• Ground coffee/beans

• Hot water

• Filter (Phin filter)

• Sugar (Optional)

Step 1: Choose Your Coffee Beans

Begin by using fresh-roasted, good-quality beans. Buy Fine Vietnam Robusta Beans. It is a great choice if you wish for a rich, bold cup with a very well-roasted character.

Step 2: Grind the Coffee

If possible, grind the coffee just before brewing to improve its freshness and aromatic capacity. Note: If the coffee is not ground well, hot water can pass quickly, leaving you with a weak cup of coffee. Fine grounds create more resistance, making water pass slowly, capturing strong flavours and helping you to get a strong cup of coffee.

Step 3: Prepare the Filter

Place a paper filter inside your pour-over brewer and rinse it with hot water. This removes any paper taste and warms the brewer and your cup. Discard the rinse water and then add the coffee grounds. For an authentic Vietnamese coffee experience, you can also use a Vietnamese phin filter that requires no electricity; just place it over the cup, put coffee and hot water in it, and your coffee will be ready in a few minutes.

Step 4: Add the Coffee

Your ground coffee then goes into the filter and is leveled out carefully (start with around 15g for 250ml of water. You can then increase or decrease it later if you prefer a stronger or weaker brew).

Step 5: Pour the Water

Pour just enough water (30 - 50 ml) to evenly saturate all of the fresh grounds and then set it aside, undisturbed, for 30 seconds. Your fresh coffee will "bloom" as gases escape. Then add the remaining water, and wait for a few minutes.

Step 6: Let It Brew

Let water flow naturally through the coffee. The process generally should take a few minutes, though the duration can vary according to the brewer, grind size, and coffee amount. When dripping stops, take away the filter, stir the coffee gently, and now it's ready.

For the best filter coffee, use good coffee beans and grounds that are authentic and natural, just like Caphe Vietnam Coffee; it has a rich aromatic flavour that gives your filter coffee an authentic taste.

Final Verdict

A great cup of filter coffee begins with quality beans and the right brewing method. Explore and experiment with bold Robusta or delicate Arabica beans, and different brewing styles to discover a flavour profile that makes your every cup worth savouring.
