There’s something magical about roasting your own coffee beans—the aroma that fills your kitchen, the crackling sound as the beans transform, and the reward of a cup that’s truly your own.

☕ Why Roast at Home?

Freshly roasted coffee is unmatched. When you roast your own beans, you get:

• Complete control over roast level (light, medium, dark)
• Cost savings over time
• A deep appreciation for what goes into every cup

Plus—it’s a really satisfying hobby.

🌱 What You’ll Need

1. Green Coffee Beans – You can buy them from specialty suppliers or roasters (choose beans based on origin, processing method, and flavor notes).
2. A Roasting Tool – Choose your method:
   • Stovetop pan (cast iron works great)
   • Oven
   • Air popcorn popper
   • Home coffee roaster (if you want to invest)
3. A Metal Colander or Sieve – For cooling the beans after roasting
4. A Wooden Spoon or Spatula – For stirring
5. A Fan or Open Window – Roasting gets smoky!

🔥 Roasting Methods (Beginner Friendly)

🥄 1. Stovetop Pan Roasting

Best for: Beginners who want a hands-on experience

Steps:

1. Preheat a heavy pan over medium heat.
2. Add a single layer of green beans.
3. Stir constantly to ensure even roasting.
4. Listen for the first crack (like popcorn popping) at ~4–7 minutes. This marks a light roast.
5. Keep going for second crack if you want a medium-dark roast (~9–12 mins).
6. Remove immediately once your desired roast is reached.

🔥 2. Oven Roasting

Best for: Small batches with minimal effort

Steps:

1. Preheat oven to 230°C (450°F).
2. Spread green beans on a perforated baking tray or regular tray in a single layer.
3. Roast for 10–15 minutes, shaking the tray halfway through.
4. Watch closely after 8 minutes. First and second cracks will guide your roast level.

🍿 3. Air Popcorn Popper

Best for: Even roasting and less smoke

Steps:

1. Add ½ cup of green beans to the popper.
2. Turn it on and let the beans spin and roast.
3. Listen for the first and second cracks (~5–9 mins).
4. Turn off when desired roast is reached and cool quickly.

⚠️ Note: Use older models with side vents—not bottom heat—for safety.

🌬️ Cooling the Beans

After roasting, cool the beans immediately to stop them from roasting further.

• Pour into a metal colander and stir or shake for 2–3 minutes
• Use a fan or open window to help
• Remove chaff (the thin papery skin that flakes off during roasting)

---

🕐 Rest Before Brewing

Let the beans “rest” for 12–24 hours before brewing to allow CO₂ to escape and flavors to settle. Store them in an airtight container away from light and moisture.
