I was at a whisk(e)y tasting last night and it was suggested that the origin of the single - one-time-only - use of the barrel with respect to bourbon aging was brought about as a result of a strong government lobby by cooperage owners and the large timber/lumber industry at that time. This would mean of course that flavor (or colour, etc.) really had nothing to do with the resulting decision and subsequent laws. It's not the first time I've heard/read this but I'm interested if anyone here has evidential proof that this theory is true, oversimplified, or nonsense?
