The way coffee beans are stored directly affects the final taste of the brewed coffee. Even high-quality coffee beans can quickly lose their aroma and flavor if not stored properly. The following recommendations aim to provide professional methods for storing coffee beans to ensure that you can enjoy fresh and delicious coffee at home. From airtight storage to the appropriate temperature and humidity, these tips will help you extend the shelf life of your coffee beans and maintain their optimal flavor. Let's explore how to properly store these precious coffee beans at home!
保持密封：
咖啡豆的保存首先需要避免與空氣接觸，因為氧化會迅速破壞咖啡豆的香氣和風味。建議使用真空密封罐或帶有密封圈的玻璃罐儲存咖啡豆，這樣可以有效地減少氧氣的進入。研究顯示，咖啡豆在暴露於空氣15分鐘後，其風味會減少約30%。因此，保持咖啡豆的密封儲存非常重要，以確保其新鮮度。
Keep Airtight: To preserve coffee beans, it is essential to avoid exposure to air, as oxidation will rapidly degrade their aroma and flavor. It is recommended to store coffee beans in vacuum-sealed containers or glass jars with airtight seals, which can effectively minimize the entry of oxygen. Studies show that coffee beans lose about 30% of their flavor after being exposed to air for 15 minutes. Therefore, keeping coffee beans airtight is crucial to ensure their freshness.
避免光線：
光線會加速咖啡豆的氧化過程，特別是紫外線對咖啡豆的影響尤甚。咖啡豆應儲存在不透光的容器中，或放置在陰暗的地方，這樣可以防止光線對咖啡豆造成的損害。根據研究，咖啡豆在陽光直射下，其香氣在一週內會損失約50%，因此，避免光線是保存咖啡豆的重要措施。
Avoid Light: Light accelerates the oxidation process of coffee beans, especially the impact of UV rays. Coffee beans should be stored in opaque containers or placed in dark areas to prevent light damage. According to research, coffee beans lose about 50% of their aroma within a week when exposed to direct sunlight. Thus, avoiding light is an essential measure for preserving coffee beans.
保持乾燥：
咖啡豆很容易吸收水分，潮濕的環境會導致咖啡豆發霉或風味喪失。咖啡豆的含水量應該保持在10-12%之間，以確保最佳的風味。建議將咖啡豆儲存在乾燥的環境中，遠離水源和濕氣。此外，可以使用含有硅膠乾燥劑的容器來保持乾燥，這能有效延長咖啡豆的保存期限。
Keep Dry: Coffee beans easily absorb moisture, and a humid environment can lead to mold or flavor loss. The moisture content of coffee beans should be maintained between 10-12% to ensure optimal flavor. It is recommended to store coffee beans in a dry environment away from water sources and humidity. Additionally, using containers with silica gel desiccants can effectively prolong the shelf life of coffee beans.
適當溫度：
儲存咖啡豆的環境溫度應保持在20攝氏度左右，這樣能夠確保咖啡豆的最佳風味。過高的溫度（超過30攝氏度）會加速咖啡豆的劣化，而過低的溫度（低於10攝氏度）則可能導致咖啡豆的風味變化。因此，應避免將咖啡豆放置在靠近爐灶或冰箱等溫度變化較大的地方。
Maintain Appropriate Temperature: The storage temperature for coffee beans should be around 20°C to ensure their best flavor. High temperatures (above 30°C) will accelerate the deterioration of coffee beans, while low temperatures (below 10°C) may alter their flavor. Therefore, avoid placing coffee beans near stoves or refrigerators where temperature fluctuations are significant.
儘管冷藏或冷凍看似可以延長咖啡豆的保存期限，但實際上這樣做會導致咖啡豆吸收水分，進而影響其風味。研究顯示，冷藏的咖啡豆在三個月內會失去約20%的香氣。因此，最好在常溫下儲存咖啡豆，並且保持密封和乾燥。
Avoid Refrigeration or Freezing: Although refrigeration or freezing might seem to extend the shelf life of coffee beans, it can actually cause them to absorb moisture, affecting their flavor. Studies show that refrigerated coffee beans lose about 20% of their aroma within three months. Therefore, it is best to store coffee beans at room temperature while keeping them airtight and dry.
適量購買：
咖啡豆的新鮮度是影響咖啡風味的關鍵因素。建議根據自身需求按量購買咖啡豆，不要一次性購買過多，以免因長時間保存而影響風味。一般來說，每次購買不超過兩週的使用量是較為合適的，這樣可以確保每次飲用的咖啡都是最新鮮的。
Buy in Appropriate Amounts: The freshness of coffee beans is a key factor affecting their flavor. It is recommended to buy coffee beans according to your needs and avoid purchasing too much at once to prevent long-term storage from affecting their flavor. Generally, purchasing no more than a two-week supply at a time is suitable to ensure that the coffee you drink is always fresh.
適量並享用前研磨：
咖啡豆一旦研磨，其風味和香氣會迅速減少。建議在沖泡咖啡前才進行研磨，這樣可以保留更多的風味和香氣。根據研究，研磨後的咖啡豆其風味和香氣在30分鐘內會損失約40%。因此，按需研磨是確保咖啡風味的最佳方法。
Grind as Needed: Once coffee beans are ground, their flavor and aroma will quickly diminish. It is advisable to grind coffee beans just before brewing to retain more flavor and aroma. Research indicates that ground coffee beans lose about 40% of their flavor and aroma within 30 minutes. Therefore, grinding as needed is the best way to ensure the flavor of your coffee.
完美的咖啡感受 - 新鮮，是絕對的關鍵。
再好的咖啡豆，沒有保存好，品質(包括風味)也是如跳下山谷一樣的劣質。正確的保存是第一步，適量的數量，也有助於經常變化咖啡豆的選擇，並且在保存上能夠得到更好的成效。
Perfect Coffee Experience - Freshness is the Absolute Key
No matter how good the coffee beans are, if not stored properly, their quality and flavor will deteriorate as if falling off a cliff. Proper storage is the first step, and purchasing the right amount helps to frequently change coffee beans and maintain their freshness. Through these strategies, you can ensure that each cup of coffee is filled with aroma and flavor, providing a perfect coffee experience.
