How to Start a Coffee Roastery

A coffee roastery and a coffee shop are different businesses. They share the word "coffee" but the operations, economics, licensing, equipment, and skill sets are largely distinct. A café is a food service business; a roastery is a food manufacturing business.

This matters from the first day of planning. A café operator learns hospitality, staff management, and customer service. A roaster learns sourcing, production chemistry, quality control, and wholesale sales. Some operators do both — owning a roastery that supplies their own café and sells wholesale — but these are two skill sets and two businesses that need to be managed separately.

What a roastery actually is

A coffee roastery purchases unroasted (green) coffee beans, roasts them to specification, and sells the roasted coffee through one or more channels. The value added is the roasting process: transforming green beans (which are inert, stable, and mildly flavoured) into the volatile, complex, perishable product that consumers buy.

The roastery's skill is in two areas:

1. Sourcing: identifying and purchasing green coffee of the right quality for the target market and price point.
2. Roasting: consistently producing a roasted profile that matches the intended flavour, at the intended roast level, across different origins and batches.

Both skills take time to develop. Most professional roasters spend 1–3 years developing their palate and roasting consistency before they consider themselves skilled. The equipment can roast coffee on day one; producing coffee that is consistently excellent takes significantly longer.

The equipment

The roasting machine is the central piece of equipment. Commercial drum roasters are described by batch capacity: a 1 kg roaster processes 1 kg of green coffee per batch; a 12 kg roaster processes 12 kg.

Supporting equipment:

• Sample roaster (if not already included): for cupping and evaluating green coffee before committing to large orders
• Cooling tray: most roasters have a built-in tray; large operations may use a standalone cooler
• Chaff collector: fine outer skin (chaff) releases during roasting and must be captured
• Scale (high-capacity): 30–60 kg capacity scale for weighing green and roasted coffee precisely, $500–$1,500
• Coffee grinder (for cupping/QC, not customer cups): a cupping grinder or lab grinder, $500–$2,000
• Packaging equipment: bags, bag sealer, one-way degassing valves (coffee off-gases CO₂ for days after roasting; bags need valves to avoid pressure buildup), label printer

Space requirements: a roaster requires adequate ceiling height (many drums are 1.5–2 m tall), ventilation for smoke and chaff exhaust (typically a duct run to the outside), and clearance around the machine. Fire suppression may be required by local code. Electrical requirements vary by machine size (small roasters: 220V single-phase; larger roasters: 3-phase commercial power).

Green coffee sourcing

Green coffee is purchased in 60–70 kg burlap bags (sometimes in Grain-Pro liner bags for moisture protection). Most importers and brokers have minimum orders of one to five bags per origin, typically $400–$800 per bag depending on quality and origin.

Importers: companies that buy from multiple origins and hold inventory in North American warehouses, selling in smaller quantities to roasters. This is where most small roasters start. You can buy one bag of a specific Colombian farm lot or Ethiopian natural-processed coffee, evaluate it, and reorder if it works. Importers handle logistics, customs, and quality screening.

Direct trade: buying from farms, cooperatives, or exporters at origin. True direct trade requires either travel to origin or strong relationships with trusted agents. It is typically only viable at volumes that matter to the producer (a minimum order of a half-container or full container is common for direct farm relationships). Many roasters who claim "direct trade" are buying from importers who have direct farm relationships — that is legitimate sourcing transparency but not the same as the roaster trading directly^[1].

Price signals: specialty-grade green coffee at the quality level required for a specialty roastery runs $3–$10+ per pound green. Commodity-grade coffee for a commercial dark roast runs $2–$4/pound. The roasted retail price needs to reflect these sourcing costs plus roasting labour and overhead.

Licensing

In Canada, coffee roasting falls under provincial food safety legislation as food manufacturing — not food service. The licensing requirements differ from opening a café:

• Food manufacturer's licence or food processing establishment registration: required in most provinces before commercial production and sale
• Premises inspection: the production space must meet food manufacturing standards (cleanable surfaces, pest control, appropriate ventilation, hand-washing stations)
• Municipal business licence
• Zoning compliance: some municipalities restrict manufacturing or smoke-producing operations in certain zones. Confirm zoning before signing a production space lease.

The licensing process is typically less complex than opening a café (no public-facing food premises) but takes a similar timeline: four to eight weeks once paperwork is filed^[4].

Distribution channels and margins

A roastery can sell through three channels, each with different economics:

1. Wholesale to cafés and restaurants

Selling roasted coffee in bulk (typically 2–5 lb bags or larger) to cafés, restaurants, and offices. Wholesale pricing is typically 40–60% below the retail bag price — a coffee retailing at $22/250g may wholesale at $10–$14/250g (depending on volume).

Gross margin on wholesale is lower than retail but volume can be high. The challenge: cafés are buyers who switch roasters regularly, and relationships require ongoing sales and service effort. A wholesale account that goes from six bags per week to zero because a competitor undercut the price is a significant revenue loss.

2. Direct-to-consumer retail bags

Selling 250g or 340g bags directly to consumers, online or through your own café or market stall. Retail pricing at $18–$28/250g for specialty coffee gives the highest gross margin — often 60–70% above the green coffee cost.

This channel is relationship-intensive and growth is slow without significant marketing investment. Building a direct subscriber base (coffee subscriptions) provides predictable revenue and higher average order value.

3. Own café

If you operate a café alongside the roastery, your beverage sales are priced at retail (the café's menu price) while your COGS for coffee is at cost. This is the highest-margin channel for the coffee itself — but it adds the full complexity of running a café business.

Most successful small roasteries operate across all three channels rather than depending on one^[3].

The economics vs a café

A roastery has different economics from a café:

Higher gross margin on the product: roasted coffee sold at retail has 60–70% gross margin vs the 70–80% on espresso drinks — comparable. But you're selling bags, not individual cups. A 340g bag sells for $22; 340g of coffee makes roughly 20–25 cups sold at $5.50–$7.00 each in a café. The café captures far more revenue from the same beans.

Lower labour intensity: a roastery with two drum roasters running full production can be operated by one to three people. A café with 150 customers per day needs four to six. Labour as a percentage of revenue is typically lower in a roastery than a café.

Higher equipment cost: a commercial roaster is a larger capital investment than espresso equipment. The payback timeline depends on volume.

Lower customer-facing complexity: no tables to bus, no milk to steam, no customers to manage in the space. The customer interaction is in the sales and tasting room, not in service.

Learning to roast

Roasting skill is not learned quickly. Commercial roasting requires understanding the Maillard reaction, the development of aromatic compounds at different temperature profiles, the difference in roasting behaviour between origins and processing methods, and the sensory evaluation (cupping) to assess what the roasted coffee actually tastes like.

Pathways to building roasting skill:

• Apprenticeship at an existing roastery: working as a production roaster for one to two years is the most common professional route
• SCA roasting pathway: the Specialty Coffee Association offers a structured certification programme for roasting
• Home roasting → sample roasting → production: starting small, developing sensory skills through cupping, and scaling up slowly
• Commercial roaster training: most roaster manufacturers offer basic training with equipment purchase

Most roasters who launch a business have spent two to five years developing the skill before commercial launch.

The honest summary

Starting a coffee roastery means starting a food manufacturing business, not a food service business. The core requirements are a commercial drum roaster ($5,000–$60,000+ depending on capacity), a food manufacturing licence, ventilation for smoke and chaff, green coffee sourcing relationships, and roasting skill — which takes years to develop properly. The three distribution channels (wholesale to cafés, direct-to-consumer retail bags, and your own café) each have different margin and volume profiles; most small roasteries combine them. A startup roastery can be operational for $20,000–$80,000 at small scale; a mid-sized wholesale operation requires $100,000–$300,000. The business differs from a café in having lower labour costs, higher equipment investment, and a production rather than service orientation.
