1. A system comprising:
one or more processors; and
a memory including instructions that are executable by the one or more processors for causing the one or more processors to:
receive an image of coffee grinds produced by a coffee grinder;
analyze the image using one or more image processing techniques to determine a representative grind size for the coffee grinds;
determine a grind setting of the coffee grinder;
select a predefined reference size based on the grind setting of the coffee grinder, the predefined reference size being selected from among a plurality of predefined reference sizes corresponding to different grind settings of the coffee grinder;
determine whether the representative grind size of the coffee grinds deviates from the predefined reference size by at least a threshold amount; and
in response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount, output a notification associated with the deviation.
