How Long Do Coffee Beans Last

Coffee lovers and industry buyers alike often ask: How long do coffee beans last? The answer depends on how the beans are stored, their roast level, and whether they are kept whole or ground. coffee beans do not spoil instantly, but their freshness and flavor degrade over time. As a professional coffee bean supplier, we provide a reliable guide to help you understand the true shelf life of coffee beans and how to preserve their quality.

Shelf Life of Coffee Beans

• Freshly Roasted Whole Beans: Typically stay at peak flavor for 2 to 4 weeks. After this period, they begin to lose aroma and taste.

• Whole Beans (Unopened Packaging): Can last up to 6–9 months if stored in sealed, airtight bags with proper packaging.

• Ground Coffee: Expires faster; usually within 1–2 weeks after grinding, as more surface area is exposed to oxygen.

• Frozen Coffee Beans: When sealed properly, beans can be stored in the freezer for 6–12 months, though slight changes in flavor may occur.

Factors That Affect Coffee Bean Freshness

1. Oxygen – Oxidation is the main reason coffee loses flavor over time.

2. Light – Direct sunlight damages aromatic compounds.

3. Moisture – Beans absorb humidity and odors, leading to spoilage.

Signs Coffee Beans Have Gone Bad

• Brewed coffee tastes flat, bitter, or dull.

• Beans look oily, sticky, or faded in color.

• Espresso has weak crema or lacks body.

• Keep beans in a cool, dry, and dark place.
