I use water for my filter grind. I have a measure cup for the beans. Then I use a wet teaspoon and stir it around in the measure cup. If I grind 10 grams the teaspoon is almost dry. If I grind 30-40 grams I have a solid water drop on the spoon. But it varies with the beans. Some beans produce more static and some less. If one or two beans get most of the water they will stick in the grinder. It’s also easier to keep the grinder clean when there is less small static particles flying everywhere.
