Pulling your espresso shot at home already shows dedication, you’re scientific and artistic at the same time (or maybe just broke and caffeine deprived, but let’s not go there). So, after you dose the coffee grounds into the portafilter, the next major key is distribution.
It's important to get the grounds evenly spread out, or you'll end up with clumps and channels, and that's a major no-go. If you don't distribute the grounds right, you'll get inconsistent extraction, and that means some parts of the coffee will be over-extracted, while others will be under-extracted. Totally unbalanced.
Back in the day, baristas and homebrewers used to just tap the portafilter or swirl it around to distribute the grounds. But that's not exactly the most precise method. That's where distribution tools come in. They help you get a consistent and controlled distribution, so you can replicate the consistency of the pros.
The following are some tools which have taken off with home brewers.
Sasha Sesjic is a former world barista, champion, revered for his contributions to espresso brewing and equipment design. His tool, the NCD (Optimal Coffee Distribution), is a precise distribution tool using a flat, adjustable base with a rotating mechanism. The tool works by spreading the grounds evenly in the portafilter through a series of light rotations, ensuring an even coffee bed. This results in a balanced extraction and helps eliminate channeling or clumping that can negatively affect flavor. Its design allows for fine-tuning to suit various grind sizes and coffee densities.
The Aro Orbit uses a circular, motion-based distribution system. The tool is placed on top of the portafilter, and the user rotates it, causing the coffee grounds to settle into a uniform bed, sweeping the grounds evenly while the tool’s construction minimizes any unwanted pressure, resulting in a more even extraction.
Barista Hustle AutoComb The AutoComb by Barista Hustle combines both distribution and leveling functions in one tool. The comb is placed in the portafilter, and through a simple mechanism, it spins to distribute and level the grounds. Its adjustable arms allow the user to customize the pressure and depth of the comb for different grind sizes.
This tool uses a series of fine needles or pins that are gently inserted into the coffee grounds. By swirling or tapping the tool, the pins break up clumps and help distribute the coffee evenly.
So, if you wanna level up your espresso game, you gotta get yourself a distribution tool. It's not just about overcoming clumpy grinder problems (are you even cleaning it right, tho?), it's about being a total coffee connoisseur. You'll be in the know, and your coffee will be that much closer to fire.
