Excellent thermo dynamics perfect for floral and fruit forward coffees using lower range brew temperature

Graycano is not your regular metal dripper. Coated in high technology coating, the graycano dripper offers excellent heat conductivity and retention.  Featuring interior protrusions called Lava Ribs, the graycano dripper promotes even extraction through maintaining water flow and temperature consistency, allowing you to accentuate the floral notes and fruit forward notes yet maintaining a balance cup quality using lower range water temperatures. 

Lava Ribs

One of the main features of the graycano is the Lava Ribs.This intentional design of the Graycano brewer mimics the lava ribs of volcanoes, manipulating variables that are specific in creating a perfect brewing environment.  These lava ribs work to promote even flow as water travels downwards, while ensuring the proper channeling of air through the pockets it created. The design and process creates turbulence and allows for even water distribution throughout the coffee. Especially when used in conjunction with the Sibarist Filters, the graycano dripper is able to create a very high consistency in drainage rate.

Perfect ThermoDynamics for a floral and fruit forward brew

In addition to the Lava Ribs, the graycano features a double-walled design with a conical center and a wrapped exterior. This works to create pockets of air under the cone between the center and exterior, assisting in maintaining a consistent and even temperature throughout the brewing process, and in the recirculation of heat from your fresh brew below. 

As a result of the aluminum metal used, the Graycano dripper is able to quickly reach the target temprature and maintaining it throughout the brewing process.  The graycano is coated with high technology coating - a  food safe and scratch resistant material and promotes a clean taste and does not interfere with the flavor of your coffee. The cast aluminum is an excellent choice for lower temperature brewing, a high heat retention and conductivity promotes a complex brew yet accentuating floral and fruity notes of the coffee.

Champion’s Choice

The graycano brewer was used at National Championships, making it to the World Stage - choice of brewer by the German National Champion Nicole Battefeld-Montgomery and Australian National Champion Martin Woelfl.

Why do we choose to carry the graycano dripper?

BREW THE MOMENT 

Brew the moment is a lifestyle concept surrounding the graycano concept. It was created based on the concept of “Enjoy the moment”, which consists on the conscious appreciation of individual moments. This is very in tune with Slow Pour Supply’s belief in creating moments of intention for yourself 

“We live on a very fast and hectic world. This makes it even more important to slow down and breathe in. That is exactly where the “Brew the moment” begins. A conscious deceleration of the hustle achieved by brewing and enjoying coffee. To appreciate the coffee and also yourself. To pause for a moment and recharge your batteries. Brew the moment with the graycano and let the world pause for a bit.” - graycano

A New Approach to Pour-Over Brewing

Most hybrid pour-over brewers let you choose between two extraction methods: immersion, where the coffee grounds remain submerged until released, or percolation, where water continuously drains through the coffee bed under gravity. While both methods produce excellent coffee, the brewer itself determines the flow rate. Once brewing begins, there is little opportunity to influence extraction without changing the recipe or switching equipment.

The SOLO SPIN Variable Flow Pour-Over Brewer approaches brewing differently. Rather than treating immersion and percolation as separate modes, it allows them to become part of the same brew. By making flow continuously adjustable, SOLO SPIN introduces a new brewing variable alongside dose, grind size, water temperature, and pouring technique.

Variable Flow Control

At the heart of SOLO SPIN is a rotating valve that adjusts flow progressively instead of switching between fully open and fully closed.

Closing the valve retains water in the brewer, creating an immersion phase. Opening it gradually introduces percolation, allowing water to drain through the coffee bed under gravity. Because the valve can be adjusted at any point during brewing, the transition between these two extraction methods is smooth rather than binary.

This flexibility allows a single recipe to evolve throughout the brew. Water can be held briefly to increase contact time, released slowly to extend drawdown, or drained freely for a cleaner finish. The brewer adapts to the coffee instead of forcing the coffee to adapt to the brewer.

How It Brews

Every adjustment to the valve changes the rate at which water passes through the coffee bed, influencing contact time and extraction as the brew develops.

A recipe might begin with a short immersion to fully saturate the grounds before gradually opening the valve to begin drawdown. Flow can then be slowed or increased throughout the brew to refine body, sweetness, clarity, or acidity according to the desired profile.

Rather than committing to a single extraction style, SOLO SPIN allows brewers to create recipes that combine immersion and percolation in whatever proportions best suit the coffee.

Zero-Bypass Brewing

Not every capability of SOLO SPIN was part of the original design intent.

During testing, Jackie Tran, inventor of the SOLO SPIN, discovered that placing a flat paper filter between the dripper and the Spin Base creates a slower drawdown while enabling zero-bypass brewing, preventing water from flowing around the coffee bed during extraction.

Although this was not an engineered feature, it expands the range of brewing techniques available with SOLO SPIN and offers another option for brewers interested in experimenting with extraction.

Built for Brewing

The larger SOLO Tritan brewer and weighted Spin Base are designed for stability during use. The base remains planted while the valve is adjusted, allowing smooth, one-handed control without disturbing the brewer. Instead of managing the equipment, the brewer can stay focused on the extraction.

One Base, Two Generations

The Spin Base is compatible with both the original SOLO PP brewer and the newer SOLO Tritan brewer. Existing SOLO PP owners can continue using the same base when upgrading to the Tritan version, preserving compatibility while expanding their brewing capabilities.

More Than a Hybrid Brewer

SOLO SPIN is designed to give brewers greater control over extraction without adding unnecessary complexity. By making flow rate continuously adjustable, it expands what a pour-over brewer can do—from familiar immersion and percolation recipes to entirely new approaches that combine both within a single brew.

Rather than asking the brewer to choose between two methods, SOLO SPIN makes flow itself a tool for exploring the full potential of your coffee.
