You can more efficiently make potent tinctures using percolation instead of a batch (maceration) process. Check out what I did in the thread below to see what I’m talking about. I was testing infusion into MCT oil at room temp but no reason the same method couldn’t be used with ethanol. Efficiencies will probably be higher with ethanol:
Also, direct infusion of carrier oils (as I do in this thread ^) is a great way to make an ingredient for edible production. As opposed to making EtOH tinctures, boiling off solvent, etc.
