I was in a little town called Sarlat, France not too long ago and talked with a couple of farmers who own a vanilla bean orchid farm on Reunion Island. They also made their own extract. I bought a pack of 20 pods, hoping that would be enough to make my own extract and they said for a tiny bottle (about 3 oz) they used over three times that and said if you use any less it's a waste of time. So I was scared away from making it myself. I'm wondering with 4 beans per cup, is it fairly potent? Has anyone that commented actually tried this particular proportion of beans to alcohol and found it really vanilla-y?
