Find a warm, dry, dark place in your home. Typically, an attic or closet works best. Avoid damp areas such as garages or basements. The moisture can prolong the drying process, as well as damage the plant.
Separate the pepper berries into small clusters based on how they'll be used. This also prevents the bunches from being crushed and speeds up the drying process.
Lay the pepper berry bunches on a clean, dry surface and tie the stems together with a rubber band. Don't twist it too tight because you want enough slack to slip it over a nail head. You can also use twine, string or a pipe cleaner to secure the stems of the bunches.
Hang the pepper berry clusters upside down from small nails in your chosen drying location. Any other manner of hanging them securely upside down will work as well, just ensure that there's room between the bunches for air to circulate and that the bunches are securely attached to their hanging device.
Collect the pepper berry clusters after they've hung between one and two weeks. The time will vary depending on how moist the bunches are when they're hung, as well as the moisture in the hanging room.
