Abstract: Grinders, analyzers, and related technologies are described herein. The grinders can hold foodstuff that is periodically ground. The analyzers can analyze the foodstuff to determine information about the state of the foodstuff. Algorithms can be used to determine how to process the foodstuff, how to use the foodstuff, and/or when to discard the foodstuff. The grinder can be a portable, rechargeable electric coffee grinder configured to monitor the freshness of the coffee beans. When coffee beans become stale, they can be discarded and the coffee grinder can be refilled with fresh coffee beans.
