propolis tincture came up in another thread, so I thought I would mention it here. handy stuff. good medicine. good for treating wood. good to make bait hives more attractive to swarm scouts. probably ends up in some perfumes. maybe even a good addition to a cocktail.
for my own use, I'm not generally very careful about the recipe. I just scrape some propolis off top cloths and other hive parts, put it into a mason jar, and cover it with 192 proof ethanol for a few weeks. then I strain it through a paper coffee filter and bottle it up.
