Understanding Roast Levels

Medium Roast

Medium brown with minimal oil

Flavor: Balanced acidity and body, caramel flavor, nuts, chocolate notes

Best for: All brewing methodsEspresso beginnersMilk-based drinks

Examples: Colombian, Brazilian, Guatemalan

Medium-Dark Roast

Rich brown with visible oil

Flavor: Lower acidity, fuller body, chocolate, spice characteristics

Espresso notes: Classic espresso profile—good crema development, works well with milk steaming

Best for: Espresso brewingMilk-based drinksFrench press

Examples: Italian roast blends, Sumatra medium-dark, Specialty espresso blends

Dark Roast

Dark brown to black with heavy oil

Processing Methods

How coffee cherries are processed after picking significantly affects flavor. This is often more impactful than origin.

Washed (Wet Processing Process)

Washed processing removes coffee fruit before drying, uses clean coffee fermentation

Flavor impact: Washed processing produces clean, bright, origin-forward flavor, higher acidity in washed coffee

Common in: Most Central/South American washed coffee, East African washed coffee

Natural (Dry Processing Process)

Natural processing dries coffee with fruit intact, then fruit removed after drying

Flavor impact: Natural processing produces fruity, sweet, wine-like flavor, heavier body, lower acidity

Common in: Ethiopian natural coffee, Brazilian natural coffee, experimental natural lots

Honey (Pulped Natural Processing)

Honey processing leaves some coffee fruit on during drying

Flavor impact: Honey processing produces sweet flavor, balanced profile, fruity but cleaner than natural

Common in: Costa Rican honey coffee, El Salvador honey coffee, specialty lots

Anaerobic/Experimental Processing Methods

Anaerobic processing ferments coffee in oxygen-free environment

Flavor impact: Anaerobic processing produces intense, unique flavors, often polarizing coffee profiles

Common in: Specialty/competition anaerobic lots worldwide

Coffee Freshness Guide

Fresh coffee matters more for espresso than any other brewing method. Here's what to expect at different ages:

1-3 days post-roast Too fresh coffee—still degassing CO2, hard to dial in espresso
5-14 days post-roast Optimal coffee freshness for espresso—coffee settled but fresh
7-21 days post-roast Great coffee freshness for pour-over and filter coffee brewing
3-4 weeks post-roast Still good coffee but starting to fade in flavor
4+ weeks post-roast Past peak coffee freshness, noticeably stale coffee

Storage tip: Keep beans in an airtight container at room temperature, away from light and heat. Don't refrigerate or freeze unless long-term storage is needed.

Smart Buying Tips

What to Look For:

  • Roast date on the bag (not "best by")
  • Origin information (country, region, farm)
  • Processing method listed
  • Tasting notes to guide expectations
  • Local roasters for freshest options

Red Flags:

  • × No roast date (only "best by" date)
  • × Vague origin ("100% Arabica" only)
  • × Extremely cheap prices for "specialty"
  • × Oily beans in clear packaging (stale)
  • × Supermarket coffee weeks/months old
