A quirk of homemade tinctures is the tendency for the extract to form a layer of sediment in the bottom of the jar. To lessen this, drip the tincture through a few layers of coffee filters to clear it from the dust-sized particles of herbs that the cheesecloth didn’t trap earlier. It’s always a good idea to store glass dropper lids separately and seal your homemade tinctures with a regular screw cap. The same sediment that can form in the bottom of the jar can also clog up a dropper pipette and be difficult to clean out.
