Beverage freshness monitor |
摘要 |
Fresh coffee is transmissible to red light, but as the coffee becomes stale, the organic compounds degrade and the brew becomes less transmissible to the light. To monitor coffee freshness, a beam of light is passed through a transparent coffee pot and the transmissibility of the brew is displayed as a measure of freshness.
