How to Start a Coffee Roastery
Roasting coffee for a living blends craft, science and a lot of tasting. It is also a food business with equipment, rules, cash flow and fierce competition for shelf space and cafe accounts. This guide explains how to start a coffee roastery step by step, from finding your niche and sourcing green beans to choosing a roaster, costing each bag and building wholesale and subscription customers.
Key takeaways
- Pick a clear niche, such as single origins, espresso for cafes or approachable blends for home brewers, so your range and marketing stay focused.
- Coffee roasting is a food business. In the UK, register with your local authority at least 28 days before trading. In the US, health permits vary by state and locality.
- Roasters create smoke, heat and odors, so check zoning, ventilation and any air quality rules before you choose a space.
- Cost each bag including green coffee lost in roasting, packaging, labor and fees, then set direct and wholesale prices.
- Wholesale accounts give volume, while online and subscription sales usually give better margins.
Specialty coffee drinkers are curious and loyal. They want to know where their beans come from, how they were roasted and how to brew them at home. That makes coffee roasting a business where a small, passionate founder can compete by telling better stories and roasting fresher coffee than big brands. It also means your customers will notice quickly if quality slips.
A quick note: this article is general information, not legal, tax or food safety advice. Rules on food registration, emissions, labeling and business permits vary by country, state and city. Check with your local authority or health department and talk to a qualified accountant or adviser before you commit.
Find your coffee roastery niche
Coffee roasting is crowded, so "good coffee" is not enough of a position. Decide who you serve and what you do differently.
- Home brewers. Approachable blends and single origins with clear tasting notes and brewing guides.
- Cafes and restaurants. A dependable espresso blend, training, equipment advice and reliable delivery.
- Offices and workplaces. Regular deliveries in larger bags, sometimes with equipment partners.
- Specialty enthusiasts. Rare lots, experimental processing and limited releases.
- Values-led buyers. Direct relationships with farms, transparent pricing or a local community focus. Only make claims you can back up with evidence.
Pro tip
Write your niche as "We roast [type of coffee] for [type of customer] who want [specific benefit]." If you cannot finish the sentence, you are not ready to choose a roaster size or design packaging.
Learn to roast and source green coffee
Roasting skill and green coffee quality decide the cup. Build both before you open.
Build roasting skill
Take a roasting course, work at an existing roastery or rent time on a shared roaster. Learn to log every roast: weight in, weight out, temperature curve, development time and cupping notes. Roast logs help you repeat good roasts and fix bad ones.
Source green beans
Most small roasters buy from green coffee importers who offer samples, smaller bag sizes and information about origin and processing. Request samples, roast them, cup them side by side and score them consistently. As you grow, you may build direct relationships with farms or cooperatives.
- Ask for samples before buying any lot.
- Record origin, process, harvest date and price paid for every lot.
- Store green coffee in a cool, dry place away from strong smells.
- Plan your buying around harvest seasons so your range stays fresh.
Common mistake
Pricing bags from the cost of green coffee alone. Coffee loses weight during roasting, so a kilo of green beans gives you noticeably less roasted coffee. Measure your own weight loss for each roast profile and build it into your costs, or you will underprice every bag.
Choose your roaster and your space
Your roaster and your premises are the two biggest early decisions. They are closely linked, because the roaster shapes ventilation, power and space needs.
Choosing a roaster
- Batch size. Match it to realistic sales for your first couple of years, with room to grow through more roasting hours.
- Fuel. Gas and electric roasters have different installation and running requirements.
- Emissions control. Some locations require an afterburner or catalytic converter to reduce smoke and odor. Ask your local authority before you buy.
- Support. Check installation help, spare parts and servicing near you.
- Used versus new. Used roasters can save money, but have them inspected and confirm parts are still available.
Choosing a space
- Check zoning or planning use for coffee roasting, since smoke and smells can affect neighbors.
- Confirm ventilation routes for the roaster exhaust and any permits needed.
- Plan room for green coffee storage, packing, a cupping area and dispatch.
- Think about a small retail counter or coffee bar if foot traffic allows.
Some new roasters start with a shared roastery or rent roasting time while building sales. It is a good way to prove demand before you sign a lease and install equipment.
Handle registration, safety and labeling
Coffee roasting follows the usual startup steps, plus food business requirements.
- Choose a structure and register the business with the relevant tax and company authorities.
- Register as a food business. In the UK, register with your local authority at least 28 days before trading. In the US, check state and local health permits, which vary by location.
- Check emissions and fire safety. Ask your local authority and fire service about roaster installation and any air quality permits.
- Arrange insurance. Consider product liability, property, equipment and business interruption cover, plus employers' liability in the UK if you hire.
- Write your safety approach. Roasters are hot and can catch fire. In the US, OSHA's general duty clause applies. In the UK, the Health and Safety at Work Act applies, and employers with 5 or more employees need a written health and safety policy and risk assessment.
- Get labeling right. Check the mandatory information for your market, such as product name, net weight, business details and any date marking. Add roast date, origin and tasting notes for customers.
Cost your coffee and set prices
Build your price from the ground up, starting with green coffee and roast loss, then adding everything else.
A simple bag costing template
Copy this table into a spreadsheet. The amounts below are made-up examples for illustration only.
| Coffee | Green coffee per bag after roast loss (example) | Bag, valve and label (example) | Labor and energy per bag (example) | Total cost per bag (example) | Retail price (example) | Wholesale price (example) |
|---|---|---|---|---|---|---|
| House espresso blend | $3.20 | $0.90 | $1.10 | $5.20 | $15.00 | $10.00 |
| Single origin washed | $4.10 | $0.90 | $1.10 | $6.10 | $17.00 | $11.50 |
| Decaf | $3.80 | $0.90 | $1.10 | $5.80 | $16.00 | $11.00 |
Add rows for shipping, platform fees and card fees on direct sales. Use your fixed costs to work out break-even: fixed costs divided by price minus variable cost per unit.
Hypothetical example
Imagine Sam runs a small roastery with made-up fixed costs of $4,000 a month. Each wholesale bag of the house blend contributes $4.80 ($10.00 minus $5.20), so wholesale alone would need about 834 bags a month to break even. Each retail bag contributes $9.80, needing about 409 bags. Sam decides to grow both: cafe accounts for steady volume and an online subscription for margin.
Watch your inventory
Track inventory turnover, cost of goods sold divided by average inventory, for both green and roasted coffee. Roasted coffee is best sold fresh, so roast to order where you can and avoid large stocks of roasted bags.
Win your first customers
Most new roasteries mix three channels: wholesale, direct online and local retail.
Wholesale to cafes and offices
Bring samples, a price list and a clear offer: delivery schedule, minimum orders, training and support. Cafes value reliability as much as taste, so promise only what you can deliver every week.
Online shop and subscriptions
Ecommerce platforms such as Shopify, WooCommerce, Squarespace, BigCommerce or Wix can host your shop. For recurring coffee subscriptions, tools such as Stripe Billing, Chargebee, Recurly or Paddle can manage billing. Check current features, pricing and privacy policies. Subscriptions have their own consumer rules: UK consumers have a 14-day cancellation right for online purchases, and many US states have automatic renewal laws requiring clear disclosure and easy cancellation.
Local presence
- Set up your Google Business Profile with photos, hours and events such as cupping sessions.
- Sell at farmers markets and local food events in the summer months.
- Partner with bakeries, delis and gift shops for retail shelves.
- Collect emails with clear consent. In the US, CAN-SPAM requires an unsubscribe option and a valid physical postal address in commercial emails.
Pro tip
Summer is iced coffee season. Publish a simple cold brew recipe using one of your coffees and offer it as a featured bag for July. It gives regulars a reason to try something new during a month when hot coffee sales can dip.

Frequently asked questions
Can I start a coffee roastery from home?
Some roasters start small at home, but smoke, fire risk, zoning and food registration rules make it tricky. Check with your local authority and insurer first. Renting time at a shared roastery is often an easier way to start.
How big should my first roaster be?
Size it for realistic sales over your first couple of years. Too small and you roast all day; too big and you tie up cash in capacity you do not use. Talk to roaster suppliers and other roasters about your projected volumes.
Do I need certifications to sell coffee?
Food registration and permits are usually required. Training and certifications in roasting or coffee grading are optional but help build skill and credibility. If you use labels such as organic, check the certification rules first.
Should I open a cafe alongside the roastery?
A small coffee bar can boost margins and brand awareness, but it is a second business with staff, licensing and long hours. Many roasters prove wholesale and online sales first.
