The Proper Bloom According to Equal Coffee

How to Properly Bloom During the Golden Blooming Period

The “bloom” is crucial for efficient coffee extraction. If the water flows too quickly, the bloom will be uneven and insufficient. On the other hand, adding too much water can result in over-blooming and premature extraction. Achieving the “golden bloom” before extraction begins requires a well-designed filter structure.The ideal design retains water thoroughly in the first half of the bloom, ensuring sufficient pre-infusion, and then allows the water to flow through in the second half.The answer lies in experiencing the bloom with the Equal Coffee Filter.

“Flow Rate” According to Equal Coffee

To retain a rich body while avoiding excess bitterness, harshness, and astringency.

We want to achieve a thicker body by using a finer grind, but this often leads to over-extraction as water pools, causing negative elements like excess bitterness, harshness, and astringency to spoil the cup. In the latter part of the drip, we want the water to pass through quickly, but the filter doesn’t allow it. These were our challenges.The solution is a filter design that preserves the coffee oils and body while allowing the water to pass through swiftly in the latter stages of the drip, minimizing the extraction of negative elements. Additionally, the filter prevents leaks during extraction, reducing the likelihood of channeling.Experience the optimal flow rate in the latter stages of the drip with the Equal Coffee Filter.

Five Key Features of the Equal Coffee Filter

1. Appropriate blooming and smooth flow
Enhances the effect of blooming and ensures a smooth flow during the latter part of the drip to prevent clogging of the filter. Solves issues of excessive extraction of bitterness, off-flavors, acidity, and astringency by ensuring appropriate blooming.

2. Stable and uniform extraction with consistent fibers
Developed to improve the variability in fiber size and density, which can cause unstable extraction. Ensures uniformity of fibers and achieves stable and consistent extraction by controlling the size of the pores.

3. Channeling prevention structure
With a structure that minimizes coffee escape, channeling is less likely to occur. Acts like a dripper's filter, catching unevenly ground coffee or failed drips to ensure smooth extraction. This results in "coffee that tastes good even when cold". Ideal for beginners in coffee making, as it minimizes the chances of failure and allows for easy dripping.

4. Balanced clarity of coffee's inherent flavor
Stable extraction leads to a well-balanced coffee flavor. Reduces unwanted flavors and brings out the natural aroma of the beans more clearly.

5. Elegant form
With a graceful appearance reminiscent of spread wings, it not only serves a functional purpose but also adds a touch of elegance to the brewing space, enhancing its aesthetic appeal.

Here’s the development story

The “Equal Coffee Filter” was born after several years of research conducted by a group of coffee experts who gathered in a small coffee studio.

After reassessing the material of the filter, we decided to adopt a Non-woven Fabric that maintains uniformity of pores more easily and allows for easier control of pore density, thus achieving stable extraction and the extraction speed and efficiency desired by researchers.

While leveraging the characteristics of this material, we focused on factors that affect dripping, such as fiber density of the filter, smooth flow throughout the extraction process, coffee drainage, removal of excess off-flavors and bitterness, coffee oils, fines, aeration, flow rate, etc. We incorporated the opinions of baristas and experts, conducting tests and prototypes repeatedly to validate our findings.

As a result of this research, we successfully developed a filter that controls the shape and density of a unique layered structure through proprietary technology, improving extraction stability and achieving the desired extraction speed and efficiency. Proper blooming is ensured, preventing excessive accumulation during dripping and efficiently extracting coffee with smooth flow throughout the process.

The adjustable design of the filter seems to breathe like a living organism, perfectly tailored to the ideal of the person dripping. It also plays a role similar to a dripper, preventing leakage from the sides and smoothly releasing to the front.

This filter maximizes the greatness of coffee beans, enriching the coffee life with a balance of acidity, sweetness, and bitterness.

From coffee novices to seasoned baristas, our filter caters to all

Equal Coffee has designed a filter that caters to both home users, enabling easy drip brewing, and baristas seeking high-quality results.
