How to Store Coffee

The Four Enemies of Freshness

Roasted coffee is a perishable product that degrades when exposed to:

• Oxygen — the primary culprit; oxidation stales flavor within days
• Light — UV radiation breaks down aromatic compounds
• Heat — accelerates chemical degradation
• Moisture — coffee is hygroscopic and absorbs ambient odors and humidity

Best Storage Practices

The Ideal Container

• Airtight — the single most important feature
• Opaque — blocks light; dark glass or ceramic is excellent
• One-way valve — lets CO2 escape without letting oxygen in (if buying specialty bags, the bag itself works well)

Location

• Cool, dry, dark place — a pantry or cupboard away from the stove
• NOT the refrigerator — condensation introduces moisture, and coffee absorbs food odors
• Room temperature is ideal (18-22°C)

How Long Does Coffee Stay Fresh?

• Whole beans: peak flavor 7-30 days after roasting; acceptable for 6-8 weeks
• Ground coffee: peak flavor for 15-30 minutes after grinding; acceptable for 1-2 weeks
• Pre-ground commercial: significantly degraded; prioritize whole beans

The Freezing Debate

Freezing can extend freshness if done correctly:

• Portion into single-use doses in airtight, moisture-proof bags
• Remove all air before sealing
• Never refreeze — thaw once and use
• Grind from frozen — some specialty baristas even prefer this for consistency

At Röstschmiede, we roast to order and recommend buying quantities you will consume within 2-4 weeks. Our bags feature one-way valves and are designed for optimal storage — simply press out excess air and seal tightly after each use.
