The system really isn’t best suited for less than 6 cups given its dynamics, and ground basket configuration. Thinking about designs of other brewers only one designed specifically for smaller pots would do well given how they too are designed. We also do not recommend brewing less than 6 cup batches as it affects the character of the cup and possibly the brewer itself. We are looking into an insert for the brew basket that will allow the option of a 2-4 cup brew in the future.
