Five Years, Five Lessons

When we started Mill Bank Coffee Co. five years ago, I don’t think I fully understood what running a roastery would involve. I knew I loved coffee and wanted to run a business, but I’m not sure I appreciated the path of continual learning I was stepping into. I was clear on the core values I wanted to build on, namely quality, sustainability and transparency, but beyond that most of it has been learned in real time.

As we approach the end of our fifth year, here are five lessons that have shaped how we work today.

1. The Roaster Isn’t the Hero

When we first started the roastery, I think I assumed that much of a coffee’s flavour came down to the roaster. I understood that origin mattered. Different soils, altitudes and climates clearly influence taste, but I do not think I fully appreciated just how much of the work had already been done before the coffee ever reached us.

Over time, that perspective shifted.

I came to realise that the role of a roaster is not to impose flavour, but to reveal it. The farmer decides when to pick. They choose how to process and dry the coffee. Those decisions shape the cup long before we load the roaster. Our job is to respect that work and showcase it, not overpower it.

That realisation runs deep into how we operate today.

When we first discussed branding, we talked about giving each coffee its own colour. At the time, I am not sure I fully understood why that mattered. It is only in recent years that it has really clicked. Our black and white branding is deliberately plain and simple. It exists to let the coffees stand on their own. Each origin has its own character, story and journey, and it deserves to be presented that way.

The roaster should not be the hero. The coffee should.

2. Consistency, But Not at All Costs

For a long time, I believed consistency was one of the most important factors in coffee. Customers find something they love and they quite rightly expect it to taste just as good the next time they buy it. That means consistency within a batch and between batches. It is fundamental to building trust.

More recently, though, I came across a point that made me pause. Coffee is a natural product. It changes from crop to crop. Weather varies. Processing shifts. A new harvest can taste noticeably different to the previous one. In that sense, coffee itself is not consistent.

The answer, I believe, sits somewhere in the middle.

Consistency is vital, but it cannot mean ignoring the natural variation of the product. When a new crop arrives, flavours may shift slightly. As a roaster, part of the job is recognising those changes and adjusting accordingly, knowing when to tweak a profile and when to leave it alone. The goal is not to make every crop taste identical. The goal is to roast each coffee to its full potential.

At the same time, I do not think it is healthy to abandon the pursuit of improvement, as that is one of my favourite things about coffee. I try to keep production roasts consistent, but I still like to experiment outside of them. Sometimes those experiments lead nowhere. Sometimes they teach you something that improves everything else you do.

Coffee does not stand still, and neither should we.

3. Coffee Is All About People

This is probably the biggest lesson of the last five years, and one that took me a while to realise.

I remember writing a product description for a Cuban coffee we had a few years ago. In several places, I read that coffee in Cuba is seen as a way of bringing people together. It is a moment in the day where everyone pauses and connects as a community.

That idea stayed with me.

The more I thought about it, the more I realised that this is true throughout the entire supply chain. It starts on a family farm. It continues in the relationship between farmer and importer. It continues again in my relationship with that importer, and then on to the customer, whether at origin or here in the UK. At each stage, coffee creates moments where people stop and connect.

Whilst it is my job as a roaster to showcase a farmer’s crop to the best of my ability, it is also my responsibility to choose coffees that are environmentally, socially and financially sustainable for everyone involved in the supply chain, and to build long lasting relationships with the people I source from rather than simply chasing the cheapest option available.

One of the things I love most about having the roastery open to the public is what happens when it gets busy. When I cannot speak to everyone, people start speaking to each other. They talk about the coffees they enjoy, how they brew at home, or sometimes completely unrelated parts of their lives. In those moments, it feels like more than just a business. It feels like a small community built around the coffee we source and roast.

4. Every Day Is a School Day

Another lesson that has stayed with me is that you can never truly “complete” coffee. There is no point where you have learned it all. Every harvest behaves differently. Weather changes flavour. Processing evolves. Even the same coffee can roast differently from one crop to the next.

I once spoke to an importer who had worked in coffee for decades. He had farmed, processed, roasted and imported coffee across several countries. After all those years in the industry, he told me he still never stopped learning and I've never forgotten that.

If someone with that breadth of experience still considers themselves a student of coffee, then perhaps that is exactly how it is meant to be. Five years in, I am still learning about roasting, sourcing, brewing and running a small business. And honestly, that is one of the things I enjoy most about it.

5. Slow, Steady Growth Is the Right Growth

There is always pressure in business to grow quickly. To expand faster. To add more products, more services, more scale.

In our first year, we roasted just over 700 kilograms of coffee. At the time, that felt significant. Now we are selling more than five times that amount each year. I do not mention that as a boast, but as a reminder of how gradual progress really works. It did not happen overnight. It happened batch by batch.

When I first started roasting, I had very little formal training. Much of it was trial and error, adjusting, tasting and trying again. Some batches were better than others. Some lessons were learned the hard way.

Fast forward to now and roasting feels more settled. Not perfect, and certainly not mastered, but more like a flow state most days. I can see what I am aiming for and I have a clearer sense of how to get there. I am still learning, and I hope I always will be, but I am more comfortable in front of the roaster than I was five years ago.

That comfort has come from time, repetition and steady improvement. The same is true of the business as a whole. We have grown, but we have grown carefully.

Looking back, I am grateful we did not try to force it. Slow growth has allowed us to build something stable, something we are proud of, and something that still feels true to why we started in the first place.

Looking Ahead

Five years feels significant, but in many ways it also feels like we are only just getting started. There is still more to learn, more coffees to discover and more improvements to make.

If you have supported Mill Bank Coffee at any point over the last five years, whether by buying a single bag, visiting the roastery or simply sharing our coffee with someone else, thank you. The business would not exist without the people who choose to support it.

We are grateful to be able to do what we do, and we are looking forward to seeing what the next five years bring.
