We discovered this BBC documentary series on Netflix recently and have found it worthwhile. Not only does it offer insight on how popular substances were discovered and evolved to wide proliferation, but also on the social impacts, brain chemistry, and role in the history of colonialism and global trade. Here is a direct video link for the first episode on Whiskey. Other shows cover tobacco, opium, sugar and more. Quite illuminating!
In looking at the history of Scottish blended Whisky Brian Cox visits a Master Blender to concoct the his perfect blend of Whisky.
