How long should coffee be used within after being brewed?

The use of coffee after brewing is commonly recommended to be within 30 minutes. This timeframe is ideal for maintaining the best flavor and aroma of the coffee, as it tends to deteriorate quickly after brewing. Beyond 30 minutes, the coffee's taste may start to change due to oxidation and the extraction of flavors, leading to a potentially bitter or stale experience.

Coffee should ideally be served hot but can also be kept in a thermal carafe to help maintain its temperature for a longer period without burning the coffee. While some sources may suggest a duration of up to 1 hour for quality, the 30-minute guideline is well-established for ensuring the optimal taste experience. This is why 30 minutes is recognized as a standard time frame in many food service settings, particularly in Navy Food Service where the quality of served items is paramount.
