Thanks, everyone, for the input so far.

Here's a good article about making them: Making Herbal Vinegars

Good to know what worked for you. I have one more recipe that calls for 50/50 water and glycerine. It is slightly frustrating as there are so many different recipes for glycerites (some herbalists say it needs more water, and another more glycerin, not to mention the ratio of menstruum to marc!!!).
I am a little nervous that I won't get the ratios right and then my tincture won't have the components in it that I want. Oh, well, I will just have to make some small batches and see what works.
I am going to check out the herbal vinegar link. Depending on the herb I am using, I may make some with glycerine/water and others with vinegar, so good to know. Thanks!

Yes, good reminder. I heard that the usual thought is that those two (vinegar and glycerites) equal about half the strength of the same herb tinctured with alcohol.

I can't recall all of the glycerines I've made - I've made so many.
comfrey
chickweed
dandelion
cleavers
elder berry
hawthorn
echinacea
red clover
nettle
and blends like roots for iron/calcium etc.
As for mold.
Have you tried leaving an inch of glycerin above the plant matter?
Do you shake it daily?
Store in the dark?
Plastic lids - not metal?
What else?....
I use a chopstick to poke the plant matter around in the jar to get rid of air bubbles.
The only time I've had mold is if I've forgotten a jar in the cabinet and find it next year!

Mm, good point. I made a glycerite tincture with a friend and we didn't know the bit about having the herb covered with glycerine, and that sometimes you need to "top it off" after a day or so if the herb soaks up the menstruum, which can cause mold if the herb is uncovered. I think I will go ahead and try it and see how it goes, remembering to shake often and make sure the herb is covered.
