The transcript doesn't state a single "best" grinder overall. While Shane expressed satisfaction with the Niche Zero (having used it for one to two years), he ultimately stated a preference for the DF64's output with his particular beans, indicating a situation where the best choice depends on individual preferences and the type of coffee beans used.
This video reviews the DF64 grinder, comparing its performance and features to those of the Niche Zero and the Ultra grinders. The reviewer tests each grinder's espresso capabilities, grinding time, and retention, ultimately assessing the overall value and suitability of each for home use.
The reviewer noted that the DF64 produced a "super thick" crema, while the Niche Zero produced crema that was described as "bright" and the Ultra grinder produced crema that was described as "super thick," though the latter's shot was noted as being slightly slower. Further detailed observations on crema consistency across the grinders were not provided.
The reviewer described the espresso from the Niche Zero as having "super fruity and great aftertaste," noting "nutty chocolate tea nuts" in the aftertaste. The aroma was described as "flowery and fruity."
The DF64 grinder has a 250-watt motor. The Niche Zero's motor wattage was not specified in the transcript; however, the Mini, a similar grinder from the same brand, has a 250-watt motor. The Ultra Grinder has a more powerful motor (wattage not specified, but described as stronger).
