1. Understand Your Needs

Before sampling, ask:

  • “What’s my target flavor profile?” (e.g., bright Nordic light roast vs. chocolatey espresso)
  • “What’s my budget?” (Grade 1 Arabica costs ~25% more than Commercial)
  • “How important is certification?” (Organic, Fair Trade, etc.)
“Swedish roasters increasingly seek balanced, sweet profiles for filter coffee – think Colombian Huila or Ethiopian Yirgacheffe.” – Flavy’s Head Sourcer

2. Evaluate Physical Quality

A. Defects (ISO 10470 Standard)

  • Grade 1 Arabica: 0-5 defects per 300g
  • Grade 2: 5-10 defects
  • Commercial: 10-15 defects

Common defects to reject:

  • Broken/chipped beans
  • Insect damage
  • Black or sour beans
Pro Tip: Use a [defect checker board] for consistent grading.

B. Moisture Content

Ideal: 10-12%
Too dry (<10%): Brittle, loses flavor
Too moist (>13%): Mold risk

(Flavy’s lab tests every batch)

3. Assess Sensory Potential

Roast Sample Protocol

  1. Roast to City+ (light-medium) and Full City (dark)
  2. Cup blind with your team
  3. Look for:
  • Sweetness (not bitterness)
  • Complexity (multiple flavor notes)
  • Aftertaste (clean finish)
“Swedish drinkers prefer bright acidity in filter coffee but heavy body for espresso blends.”

4. Verify Logistics & Ethics

Ask suppliers:

  • “What’s the harvest date?” (Within 12 months)
  • “Can you share farm photos/coordinates?”
  • “What’s the carbon footprint of Sweden?”
Flavy Guarantee: All beans come with transparency reports and carbon-neutral shipping.

5. Start Small, Scale Smart

  • Order 5kg samples before committing to bulk
  • Track roast yield and customer feedback
  • Adjust origins/processing methods seasonally
