For how long should a coffee grinder used for 2 lb/week be cleaned and calibrated?

The recommended interval for cleaning and calibrating a coffee grinder used for 2 lb/week is every 6 months. This timeframe balances the need for maintaining the quality of the grind and the overall performance of the grinder while reducing the risk of taste contamination from old coffee particles. Regular cleaning prevents oil buildup and ensures that the grinder operates effectively, which is crucial given the frequency of use.

Using the grinder for 2 lb of coffee per week leads to a significant buildup of coffee oils, dust, and residues if not maintained properly. Over time, these residues can affect the taste of the coffee being produced, hence, a 6-month schedule is a practical approach that allows for consistent quality in beverage preparation.

Longer intervals, such as every year or every 18 months, would not adequately address the necessary maintenance for a grinder in regular use. These longer periods could lead to a decline in grind consistency and overall coffee quality due to the accumulation of old coffee grounds and oils.
