I wont buy essence without the mustard in the quill. Too many out there tincturing and cutting product these days. If there is no mustard at all in a bottle I am quite skeptical.
The mustard is a fatty substance that helps to hold and attach the essence once it has been sprayed for defense or during mating season. Never could figure why some want it removed.
I've been collecting it all summer and couldn't figure out what the difference would be but guess if that's what my buyer wants then I'll keep and use the mustard for my own lures. Thanks for clarifying this for me!
