📦 为什么咖啡豆需要特别储存？

Why Does Coffee Storage Matter?

咖啡豆和面包一样，越新鲜越好。一旦接触空气、水气、阳光或高温，风味就会逐渐流失。
Just like fresh bread, coffee tastes best fresh. Exposure to air, moisture, light, or heat can quickly degrade the flavor.

🛡️ 四大敌人：空气、水、光、热

The Four Enemies: Air, Moisture, Light, Heat

• 空气（氧化） → 加速变质

• 水气（湿气） → 引发霉变

• 阳光（紫外线） → 分解芳香物

• 高温 → 香气快速挥发

• Air (Oxidation) → Causes staleness

• Moisture (Humidity) → Leads to mold

• Light (UV) → Breaks down aroma compounds

• Heat → Speeds up aroma loss

🫙 如何正确保存咖啡豆？

How to Store Coffee Beans Properly

✅ 使用密封罐（推荐带有单向排气阀）
✅ 存放在阴凉干燥处，避免厨房高温区
✅ 分装小包使用，减少频繁开封
✅ 2-4周内喝完最理想

✅ Store in airtight containers (valve jars recommended)
✅ Keep in a cool, dry, dark place, away from heat sources
✅ Portion into smaller bags to avoid repeated opening
✅ Best consumed within 2–4 weeks

🧊 冷藏 or 冷冻，可以吗？

Fridge or Freezer — Yes or No?

• 冷藏 ❌ 不建议：水气波动大，易受潮

• 冷冻 ✅ 条件可行：真空密封 + 分装使用前解冻

• Fridge ❌ Not Recommended: Moisture risk is high

• Freezer ✅ Optional: Only if vacuum-sealed & portioned properly

Tips: 取出冷冻豆时需先放至常温，避免结露！
