Recently we bought a single dose grinder. A grinder without a hopper, where you add the beans just before grinder.

The big benefit of a single dose grinder is you can easily change beans on the fly. Use a different coffee for your pour-over in the morning than for your espresso after dinner.

Adjusting your grind is also easier. As you measure the beans separately, there is only one variable to adjust: the grind-size With a regular grinder it's always complex to adjust the grind-size and the weight of the beans at the same time.

I regularly set the grinding to coarse for my V60 filter and weight 15 grams beans, and then change it to 10 grams with a fine grind for a single dose espresso.

The grinder I have selected is the Niche Zero. I like the clear settings of this grinder, which makes it easy to get back to the tuned settings after changing brewing method. The Niche Zero looks great (at least that's my opinion) and overall has good reviews.

Weighting your beans can be done on a regular scale. But I came across a nice gadget, a cup with a built-in scale, the Subminimal Not a must, but actually a fun "nice to have"

Overall a nice set to experiment with different brewing methods and coffee roasts. In the past I always ordered at least a kg of a specific coffee because it took time to tune the grinder. Nowadays I often buy several roasts of 250 grams each or try-out packages of roasters.
