The belief among some archeologists that Europeans introduced alcohol to the Indians of the American Southwest may be faulty.
Ancient and modern pot sherds collected by New Mexico state archeologist Glenna Dean, in conjunction with analyses by Sandia National Laboratories researcher Ted Borek, open the possibility that food or beverages made from fermenting corn were consumed by native inhabitants centuries before the Spanish arrived.
Dean, researching through her small business Archeobotanical Services, says, “There’s been an artificial construct among archeologists working in New Mexico that no one had alcohol here until the Spanish brought grapes and wine. That’s so counter-intuitive. It doesn’t make sense to me as a social scientist that New Mexico would have been an island in pre-Columbian times. By this reasoning, ancestral puebloans would have been the only ones in the Southwest not to know about fermentation.”
Read the whole thing as it's a pretty good description of the work. I don't know of any place that didn't have some sort of alcoholic beverage.
