As a premium coffee chain grows from a handful of sites to a regional or national estate, one question tends to come up in the boardroom sooner or later: should we start roasting our own coffee?
It is a fair question. Coffee is the product your customers come back for, and owning how it is made can feel like the natural next step. But roasting is a business in its own right, with its own equipment, skills, supply chain and risks. For most chains, the decision comes down to whether the control and margin you gain outweigh the cost and complexity you take on.
This article sets out the facts on both routes, roasting in-house and buying from a wholesale roaster, so you can weigh them up against your own plans.
Why Might you Want to Roast Your Own Coffee?
Some of the UK's best-known coffee brands roast their own, and for good reason. When coffee is central to your identity, bringing roasting under your own roof can sharpen your offer, strengthen your story and, at the right scale, improve your margins.
What Are the Benefits of Roasting In-House?
Lower cost per kilo at scale. Green (unroasted) coffee costs considerably less than roasted coffee bought wholesale, because you are no longer paying for someone else's roasting, packing, overheads and margin. For a chain using large, steady volumes through a well-run central roastery, that difference can add up to a meaningful saving on every cup.
Complete control over what you serve. You choose the farms, the origins, the processing methods and the exact roast profile. If you want your house espresso to taste a particular way, you can develop it, adjust it and keep it there. Nobody else's range or roasting style shapes your menu.
A stronger brand story. "Roasted by us" is a powerful message for a premium brand. It gives you authentic content about sourcing trips, farm relationships and roast development, and it can help justify a premium price point in the customer's mind.
Freedom to experiment. With your own roaster you can run limited-edition single origins, seasonal releases and small micro-lots whenever you like, without minimum order quantities or waiting on a supplier's schedule.
Extra revenue streams. Your own roasted beans can be sold as retail bags in store and online, offered on subscription, or even supplied wholesale to other businesses once your operation is mature.
Customer experience. A visible roastery in a flagship site creates theatre, a reason to visit and a talking point that sets you apart from competitors.
Roasting Brings Added Complexity
The benefits are real, but so is the commitment. Roasting is not a bolt-on to a coffee shop business; it is a separate manufacturing operation that needs its own people, premises, processes and capital.
High upfront investment. A production roaster capable of supplying a multi-site chain is a significant capital purchase, and the machine is only part of it. You will also need suitable premises, ventilation and extraction, often an afterburner or emissions control to satisfy your local authority, plus green bean storage, weighing, packing and sealing equipment. Planning permission and environmental health approval can add both cost and time before you roast a single batch.
A new business arm to run. Someone has to own roasting day to day. That means recruiting or training skilled roasters, quality control staff and production managers, and paying for them whether volumes are up or down. It also pulls leadership attention away from what drives your sales: your sites, your teams and your customers.
Sourcing green coffee yourself. Buying green coffee well is a specialist skill. You will need relationships with importers or producers, the ability to cup and assess samples, an understanding of harvest calendars and contracts, and the cash flow to buy in sufficient volume. You also carry the risk if a shipment arrives below standard or late.
Perfecting and protecting the roast. Developing a roast profile takes time, and keeping it consistent takes more. Green coffee changes as it ages and from one harvest to the next, so profiles need constant cupping and adjustment. Any drop in consistency is felt directly by customers across every one of your sites.
Distribution to your sites. Once the coffee is roasted, you have to get it to every location on time, at the right freshness, in the right quantities. That means vehicles or couriers, scheduling and the cost of failed or late deliveries.
Stock and inventory management. You will be managing two types of stock: green coffee, which must be stored correctly and used before it fades, and roasted coffee, which has a far shorter window of peak freshness. Forecasting demand across many sites, avoiding waste and preventing stock-outs all become your responsibility.
Full exposure to coffee prices. When you buy green coffee directly, every movement in the commodity market lands on your costs. In volatile years, that can wipe out much of the saving that made in-house roasting attractive in the first place.
Compliance and certifications. Food safety, traceability, packaging and labelling rules all apply to a roastery. If your customers value Fairtrade, Rainforest Alliance or Organic credentials, gaining and maintaining those certifications is another layer of auditing and administration.
The Usual Route: Buying From a Roaster
Most coffee chains, including many premium ones, buy their coffee from a specialist wholesale roaster. Here is what that route offers, and where it has limits.
The Benefits
No added complexity or large investment. There is no roasting machinery to buy, no roastery to fit out and no planning or emissions approvals to secure. Your capital stays in your sites, your people and your growth.
Access to roasting expertise. An established roaster brings experienced roasters, green buyers and quality control teams who cup and refine every batch. You benefit from that knowledge without having to build it yourself, and you usually have a range of blends and single origins to choose from, or the option to develop a bespoke blend.
Distribution to every site. A wholesale partner handles roasting schedules, packing and delivery, so each location receives fresh coffee without your team organising logistics.
Wider support. Many wholesale roasters offer far more than beans: barista training, equipment supply, engineer servicing and maintenance, and branding support such as private label packaging and point of sale material. For a growing chain, having coffee, machines and service under one relationship simplifies operations considerably.
Scalable from one site to hundreds. A wholesale roaster has capacity built in. Opening ten new sites means a larger order, not a larger roastery.
Better rates as you grow. Pricing is typically tiered by volume, so the cost per kilo often improves as your estate expands.
Supply chain resilience. Larger roasters source from many origins and producers, hold buffer stock and have established import relationships. If one origin has a poor harvest or a shipment is delayed, they are better placed to keep your supply steady.
Price protection when markets spike. Coffee is a volatile commodity. Arabica futures broke their 1977 record in late 2024, passed $4.29 per lb in February 2025 and set a new all-time high of almost $4.38 per lb in October 2025. A chain on a fixed-price supply contract with a wholesale roaster is shielded from those swings for the length of the agreement, which makes costs and menu pricing far easier to plan. A chain buying green coffee on the open market absorbs every rise in full.
The Drawbacks
A higher price per kilo than green coffee. You are paying for the roaster's expertise, overheads and margin. At very high volumes, this is where in-house roasting can win on pure bean cost.
Less hands-on control. Even with a bespoke blend, you are relying on another business to roast to your standard. Choosing a roaster with strong quality control and a consultative approach matters.
Reliance on one supplier. If your roaster has a problem, so do you. It is worth understanding their contingency plans, stock holding and service levels before you commit.
Contract terms cut both ways. A fixed price protects you when markets rise, but if prices fall during your contract you may pay more than the market rate until it is renewed.
A less personal origin story. You cannot say "roasted by us". Private label and white label options, where coffee is roasted to your specification and sold under your brand, close much of that gap.
To Wrap Up
Roasting in-house offers full control, a compelling brand story and, at high and steady volumes, a lower cost per kilo. In return, you take on a capital-heavy manufacturing operation, a specialist workforce, green coffee sourcing, distribution, stock management and full exposure to commodity prices.
Wholesale costs more per kilo, but removes that complexity and brings expertise, scalability and price protection with it.
For chains with very large volumes, a central production site and the appetite to run a second business, in-house roasting can pay off. For most multi-site operators, a strong wholesale partnership delivers consistent quality across the estate while leaving the business free to focus on its customers.
