About us

HIGH QUALITY IS AN INVESTMENT—IN TASTE, EXPERIENCE, AND LONGEVITY.
WE ACHIEVE THIS THROUGH TOP-SEGMENT COFFEE, STRONG SUPPLIER RELATIONSHIPS, AND CONTINUOUS DEVELOPMENT.

Approach

High quality makes something an investment. In taste, experience or longevity. By product development, supplying high quality coffee, building long term relationships with suppliers and only settling for top-segment products.

The selection of our coffee is based on blind cuppings. We believe that every coffee deserves an equal chance on the cupping table.
Sourcing and selecting only the best on the table, being either a damn fine classic or an exceptional uncommon coffee. Always on the look-out for something unusual, outstanding or simply delicious. All our coffees are fully traceable to their farm, most of which we work directly with the farmer or processing plant, we work closely with all of our suppliers.

Selection

What you can expect from all our coffees is a clean, flavorful and complex cup without compromising for lack of depth or solubility. If there are 50 coffees on a cupping table we might not want to get any, but sometimes there are only 4 on the table and we’ll take everything that’s available. A personal style that can be noticed in every coffee we offer.

Either classic profiled: for example the best to our opinion out of dozens of classic profiled Brazilian coffees. Or uncommon profiled, where you can expect something special, either being an exclusive lot, ultra—high-end coffee, rare variety, unique origin or anything that makes a coffee something you’ve probably not had before. We aim for stellar coffees.

Homage

When the iconic Van Nelle Factory, home to our roastery, was designed nearly a century ago, its architects broke new ground by embracing innovative materials, a bold futuristic aesthetic, and a revolutionary approach that prioritized function over form. Despite this functional focus, the result was an architectural masterpiece that continues to inspire to this day.

Mentality

We like to think reasoned, future forward and quality driven. Defining our choices based on an unbiased blend of facts and individual taste. It’s not about assuming or following, it’s a matter of concrete decisions based on our vision and hard data. You can find this in our choice of packaging, interior and of course our selection of products.

no-nonsense

And lastly: no-nonsense, cut the crap, or “niet lullen, maar poetsen” as we say in Rotterdam—let’s cut to the chase. Making matter concrete, turning ideas into action, and always delivering on what we promise, with a relentless drive for quality and results, ensuring every detail serves a purpose and creates real, lasting impact.

Vision

Innovation and sustainability are what make today good and tomorrow better. Direct trading with suppliers, developing long-lasting products while giving attention to circularity, waste-reduction and inspire others to do so too.

Our coffee roaster is the state-of-the-art Loring S35 Kestrel, one of the most energy efficient coffee roasters around. Our energy supplier has Gold Standard certification (meaning CO2 neutral gas and only electricity from renewable sources) and we try to reduce, reuse and recycle wherever we can.

In our roastery our goal is to get the best out of every bean.
There’s a Sovda color sorter to sort the coffee beans to perfection. A space designated for quality control. A tasting room. And there are dozens of ideas the future may bring. We’re not trying to be saints, but we think further than a leaf on a label.

Location

We’re a specialty coffee roastery based in one of the old warehouses of the Van Nelle Factory located in Rotterdam, The Netherlands.
The Van Nelle Factory* once used to be the biggest coffee roastery in all of Europe. It is quite rare to find a pre-WWII building in Rotterdam, let alone it being a coffee roastery, let alone one that is now a listed UNESCO World Heritage monument.

The factory was built in the New Objective style in the 1920’s, being one of the first buildings ever where concrete was the main material. Now you know, how concrete, just like coffee was and is inseparable from the Van Nelle Factory.
After roasting for 65 years, in 1995 the last bean was roasted and production of the Van Nelle brand moved elsewhere. From this moment on it was thought that no bean would ever be roasted again at this historical venue. But then we came 26 years later and reignited the tradition in a future forward path.

Founded in 2021

“In 2012 I was in Copenhagen following an internship. Coffee was nothing more than a morning fuel to me back then. When I walked into the same cafe for the 2nd time in a week the barista recognised me and remembered my order. It made me feel welcome. That tiny gesture made me realise the value of what a cup of coffee can bring. From that moment on I knew: I also wanted to work in coffee.

More than a decade later my career has been a wild ride. From starting numerous brands, companies and competing in many coffee competitions. Being on the winner’s podium of quite a hand-full such as National Brewers Cup, Barista Championship, Latte Art Championship and Aeropress Championships, with the crowning achievement of winning Coffee Masters London 2019.

After being head-roaster for 8 years, and an entrepreneur in coffee for 6, starting A Matter of Concrete made it possible to set up a dream roastery. Putting all the inspiration and ideas that I’ve gathered over the years from all over the world into this dream-coming-true.

I love the indefinite world of coffee.
You can learn something new every day,
just never stand still.”

Packaging

WE LOVE PACKAGING DESIGN BUT HATE WASTE,
STRIVING FOR A BALANCE BETWEEN AESTHETICS AND SUSTAINABILITY WITH REAL, FOOD-GRADE SOLUTIONS THAT ARE MORE THAN JUST A LEAF ON THE LABEL.

AMOC JAR

Our AMOC jars are made from fully recyclable PET. They’re lightweight, requiring minimal resources for production, and most importantly, they’re reusable for (almost) an eternity. Designed for both practicality and sustainability, they help reduce waste while keeping your coffee fresh. Once empty, simply refill it instead of throwing away packaging.

Refill

If you, like us, think throwing away a bag after a single use is nonsense, we’ve found a better way. Due to regulations, standard coffee pouches can’t be reused, and many “green” certifications are misleading. That’s why our refills come in a vacuum-packed food-grade PP bag—40% lighter than coffee bags, easy to recycle, and reducing shipping volume.

Kilo

Finding sustainable packaging that also protects coffee quality is a challenge. We refuse to let great coffee go to waste after so much energy, water, and care have gone into it. That’s why we chose our KG bags for their balance of recyclability and excellent barrier properties. Under the right conditions, they are recyclable while keeping your beans fresh.
