The Mahlkonig Guatemala coffee grinder is available in 3 configurations. The grinder features a classic rectangular spout with a clamp - great for bulk grinding into bags. The Guatemala Filter includes a slanted, low-retention spout with a spring-loaded chute knocker and an adjustable fork which attaches to the body to accommodate batch-brew baskets. The Guatemala Lab configuration includes the same low-retention spout as the Filter version and ships with a grounds cup and stand. The Lab is well suited for single cup brewing and cupping.
