Cracking Cacao Beans
How to crack roasted cacao beans cleanly so the nib separates from the husk. The Champion Juicer is the best tool for it.
Remove the screen from a Champion Juicer and run your roasted beans through. You'll get cleanly cracked pieces with most husks detached and nibs intact, ready for winnowing.

A wide, shallow tray placed under the juicer to collect cracked nibs and husks as they fall.
The Champion Juicer 2000 has been discontinued and can be a real pain to track down. Chocolate Alchemy carries the USA model when in stock. Beyond that, eBay and Facebook Marketplace are genuinely good options. I've bought mine from both. Look for a used Champion in working condition and confirm the auger and screen are included.
Let roasted beans cool fully to room temperature before cracking. Warm beans are slightly soft and crack less cleanly. This usually means waiting at least an hour after the roast rest.
Pull the screen out of the Champion Juicer. This is the perforated insert that normally separates juice from pulp. Without it, the auger cracks the beans rather than grinding them. Do not skip this step.
Place a wide tray under the juicer to catch nibs and husks as they fall; they come out together and you don't want to be chasing them across your counter. Cracking also throws light husk pieces into the air more than you'd expect. Outdoors is easiest. If you're working inside, a glovebox enclosing the juicer keeps flying husks contained and your kitchen intact.
Feed beans in slowly and steadily. The auger does the work, so don't dump a full batch in at once or force it. A 1 lb batch goes quickly. Everything comes out together: cracked nibs and loose husk mixed.
You should see mostly intact nib pieces, ranging from roughly half a bean to small fragments, with husk sitting loosely around them. Some testa will still cling to nibs; winnowing handles that. A lot of fine powder means too much force was applied. A small amount of dust is unavoidable.
Separate the light papery testa from the heavier nibs using airflow. A fan, a hair dryer on cool, or pouring between two bowls outside on a breezy day all work. After winnowing, nibs go directly into the melanger or grinder. Store any nibs you're not using immediately in an airtight container. They oxidize faster than whole beans.
A heavy-duty zip-lock bag and a rolling pin works for small batches: spread a single layer of beans, seal, and roll with firm even pressure. A dedicated bean cracker from Chocolate Alchemy is another solid option. Avoid blenders or food processors, which grind far more than they crack.
Log your crack and winnow notes alongside your roast profile and tasting results in Cacao Journal. The more you record, the faster you dial in your process.
