How to Choose Coffee Beans - The Quality of Coffee Beans

Selecting Coffee Beans and Their Quality

The freshness of green coffee beans starts counting from the time they are roasted.

Freshly roasted coffee beans will begin to degas, a process that continues for about 3-5 days. When all the gas has been completely released (about a week), the freshness of the coffee beans will begin to decline over time.

FrontStreet Coffee roasts fresh daily, and if beans are not sold within a month, they are discarded and destroyed to maintain consistent quality.

How to Judge Coffee Freshness

1. Oil Surface: For light to medium roasts, no oil is visible; for dark roasts, the darker the roast level, the more oil appears.

2. Aroma: Freshly roasted coffee beans have a rich, intense aroma.

3. Foam: Fresh coffee beans still contain some unreleased gas, so filter bag expansion is not due to added nitrogen, but rather the packaging of fresh beans.

When hot water is poured over ground coffee powder, foam will appear on the surface. The coffee beans seem to be breathing, producing some bubbles and oils.

Production and manufacturing dates should be clearly marked. Yedou Coffee notes the manufacturing date and recommended usage period for each production batch.

Best tasting period: 3-6 months for roasted beans; 4-6 weeks for ground beans.

Now do you understand how to choose coffee beans and determine their quality?

Coffee bean packaging should be bags with one-way degassing valves. These are designed to release air from inside the bag because fresh beans emit carbon dioxide, which expels gases from the bag, maintaining bean freshness and reducing oxidation.
