Brewing Modes

The S1 Air has a lower starting weight, which is better for tiny doses. This helps when weighing small amounts of coffee or tare weights. The S1 Mini requires at least 0.5g to register accurately. For most espresso shots, both work well. The S1 Air is better for micro-dosing or precise tare adjustments.
Battery Life

Audio Controls

The S1 Mini data does not mention a mute feature. You will hear the standard beeps with the S1 Mini unless it has an unlisted mute option.
