The caffeine wrench is like the bulldog of coffee tools: powerful yet compact, and so ugly it’s cute. Hold it by its rubber handle as you use the 8 mm, 12 mm, or 13 mm wrenches on each side to remove your steam wand tip. The 8 mm wrench in the center also has a contoured wand scraper perfect for getting rid of milk build up on the steam wand. A pointy gasket probe on the right can be used as a soft gasket puller on many groups, allowing you to regularly inspect the group gaskets. A flathead filter basket pry/screwdriver located on the left lets you pop out your portafilter basket with ease. It also works as a screwdriver to access your group for maintenance. Handy, hefty, and small, you’ll wonder how you ever got along without it.
