About Bean Logic
Coffee should make more sense.
Most coffee is roasted in bulk, with fixed profiles, and then sold as a finished decision. You're left to guess whether it'll actually suit how you drink. Bean Logic changes that.
Built around how you drink
You choose the coffee. You choose the roast. We roast it to order around how you actually drink it — whether that's espresso, milk, or filter. No fixed profiles. No bulk roasting. No guesswork.
Not roasted for the shelf
Traditional roasters scale by producing large batches. Bean Logic works differently. Every coffee is roasted in small batches, for individual orders, so it's fresher, more flexible, and better aligned with what you actually want in the cup.
Who's behind it
I'm Rob, and I'm based in St Albans, Hertfordshire. Bean Logic started the way most obsessions do — gradually, then all at once.
It began with an AeroPress and a Fellow Opus grinder. I was grinding beans at home, learning what freshness actually tasted like. Two years in, I invested in an Rocket Appartamento TCA espresso machine and a Giannino grinder, and the obsession deepened. I went through grinders — a DF83V, Weber products, various experiments — always chasing a better cup.
Eventually I started asking: what if I roasted my own? I bought green coffee from Green Coffee Collective and Redber Coffee, picked up a Gene Cafe Roaster off eBay, and roasted about 50 batches. The Gene Cafe taught me a lot. It also taught me I needed more control.
So I upgraded to a Kaleido M2 Pro — a precision drum roaster I can programme from my laptop. Now I plan every roast in advance: drying phase, Maillard phase, first crack, development time. Before each roast I take moisture readings, weigh the beans, measure density. I log everything. I use AI tools to help model roast plans based on origin, process and altitude. And I publish all my roast data on Roastetta so the process is completely transparent.
That data obsession is what Bean Logic is built on. Every coffee I source is traceable back to a named producer. I buy from specialty importers, and now directly through warehouse auctions where exceptional small lots become available. Every roast is planned specifically for that coffee — not a fixed house profile applied to everything.
Part of what pushed me to build this was frustration with the alternative. Ordering from traditional roasters — the Grinds and Raves of the world — meant coffee that could be two or three weeks old by the time it arrived. The only brand I genuinely enjoyed was Square Mile, because they roasted fresh to order. But the options were limited and there was no way to experiment with roast levels or tailor it to how I actually drank.
What I do is operationally impossible at scale — big roasters simply can't roast individually to order for thousands of customers. But on a small scale, with my Kaleido M2 and the system I've built around it, I can do exactly that. Every bag is roasted specifically for your order, to the roast level you've chosen, for the way you drink.
I'm based in St Albans and roast for customers across Hertfordshire and beyond. If you're local and want to talk coffee, I'm always up for it.
Built by someone who cares about the details
The goal isn't to complicate things. It's to make choosing coffee simpler, clearer, and more reliable — and to make sure what arrives at your door was roasted with your cup in mind, not the batch.
