Rehydrating dried out cigars is a simple process that can help restore the cigar’s original flavor and texture. To rehydrate cigars, you will need a humidor or other airtight container, a damp cloth or sponge, and distilled water. Begin by lightly wetting the cloth or sponge with distilled water. Place the dry cigars in the humidor or airtight container and then place the damp cloth on top of them. Seal up the container to keep it airtight, making sure to leave enough room for some circulation within it. Allow your cigars to sit undisturbed in this environment for several days until they have fully rehydrated; checking every day to ensure that there is still moisture present in the container and that no mold has developed on your cigars. Once they are fully rehydrated, move them back into your regular humidor where you can enjoy them at their best quality.
