I bought a bag once and used it in the kettle. You can smell the JD as soon as it's opened, as I believe (at least at the time I bought them) it was the oak from the barrels they used to age the bourbon. Not sure if it is still being produced and marketed this way.
It is not overpowering, fairly mild. I just thought the cost of the small bags were a bit too high and not worth the money. How much did you pay for the bag ? I recall the small bag I bought was $10+.
