It's been a week since I started the tinctures, so maybe it's time for a quick update. Every day I shake all of the jars, which, in addition to the functional benefit of encouraging the infusing, also gets me in the room to monitor the process.
The floral tinctures are already completed. The hibiscus was the first one done, followed shortly by the rosemary, juniper, lavender, sassafras, and a few others. There's no easy way to tell when they complete; you just have to taste them every day (taste, do NOT just smell, as the smell is pretty rancid). Then, when they're done, you remove the solids, rinse the jar, and re-jar the liquid.
Most of what's left still infusing are barks and woody bits, though I did add a jar of lemon tincture to the shelf a few days ago. It's already beautiful and yellow!
