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.”
Not only does historical evidence for fermented beverages exist for surrounding native groups, but people around the world have found ways to alter their consciousness, she says: “Wild yeast blows everywhere.” In the Middle Ages in Europe, “Everyone drank ale because the fermentation purified water.” Egyptian tombs contained loaves of bread “that we used to assume were to eat, but they’re actually dry beer: put bread in water, you get beer.”
Closer to home, the Tarahumara Indians in northern Mexico to this day drink a weak beer called tiswin, made by fermenting corn kernels.
Could ancestral puebloan farmers — whose ancient mud and rock homes have been found in New Mexico, Arizona, Utah, and Colorado — have done the same?
To check her hypothesis, Dean presented Borek with three types of samples: pots in which she herself brewed tiswin, brewing pots used by Tarahumara Indians, and pot sherds from 800-year-old settlements in west-central New Mexico. The question: would analysis support the idea that ancient farmers enhanced their nutrition — and perhaps enjoyment of foods — by manipulating wild yeast and corn mixtures centuries before Columbus?
Borek, working under a Sandia program that permits limited use of Sandia tools to aid local small businesses, used gas chromatography and mass spectrometry (rather than destructive solvents) to analyze vapors produced by mild heating of the pot samples.
From Dean’s pots, Borek developed a profile of gasses emitted from a known tiswin source. Then he examined Tarahumaran pots to see whether the gaseous profiles corresponded. Finally he examined pot sherds that had been buried for centuries to see if the obviously weakened fumes would match, in kind if not in volume, his previous two samples.
Comparing peaks across the three data sets showed the presence of similar organic species, Borek says, though more work must be done before positive conclusions can be drawn.
“We see similarities. We have not found that ‘smoking gun’ that definitely provides evidence of intentional fermentation. It’s always possible that corn fermented in a pot without the intent of the owner,” he says, “and that it wasn’t meant to be drunk.”
Analysis is now underway to highlight patterns of organic species that might provide a more definite, intentional result.
“There appear to be consistencies across the modern home brew and Tarahumaran pots,” Borek says. “We are currently examining all data to look for markers that would indicate intentional fermentation occurred on archeological articles.”
The work opens new, unexpected doors, he says, for understanding the human past by means of gas chromatography and mass spectrometry.
Sandia researcher Curt Mowry is examining data and comparing all sets across the provided references, Tarahumaran pots, and ancient samples.
The results were presented by Borek in a talk at the Materials Research Society fall meeting in Boston last week.
The equipment used in this study is commercially available hardware, modified by Sandia to investigate traces of organic materials in the ambient air of the Washington DC Metro system and on weapon components and materials.

Without distillation, there's no way that a fermented beverage would have the necessary alcohol content to become "firewater". It was called so, because if spat upon a campfire, it would flare up if it were 50% alcohol, being 100 percent proof that it was indeed a potent potable.
“The belief among some archeologists that Europeans introduced alcohol to the Indians of the American Southwest may be faulty.”
The Europeans with their OCPD thought the Indains to abuse alcohol.
Obsessive-Compulsive Personality Disorder?........
Weak beer and home brew ping in one.
This stuff sounds pretty bad.
Tizwin, sounds onomatopoetic.
And known affectionately to Pale Faces as Bourbon.
bingo that.....firewater.........I know.
I’m German / Cherokee........the problem with that
is everytime I get drunk, I wanna scalp myself
They may be calling any undistilled alcoholic beverage "beer."
Chicha, the Inca beverage made out of corn is an example.
It wouldn't pass the German legal standard for beer, but it's sometimes called a "corn beer".
Kvass, the undistilled Russian beverage made out of fermented rye bread may be another example.
Gimme another redman! Hic!
Right!
What’s funny about that? I’m Indian and I still don’t know or want to know what a rake or hoe is. LOL (or a lawn mower)

Kvass is not an alcoholic beverage.
self ping for later
Beer Ping!
A low to medium ping list aimed at all of us who, well, love our beer…
FReepmail rzeznikj at stout to be added or struck from the list…
Sorry to hear about your dog. I lost my second Black Lab last month, and the first one this time last year. They were old, but it still sucks.
Go drown your sorrows for a while but remember that tomorrow is another day. ;)
P.S. That “Beer Hunter” sure looks like Mitt Romney, LOL!
Our black lab was just a shade over 12 years old and had a gigantic tumor removed from her hind leg about 6 months ago only to have it grow back bigger and badder. We got her when I was 15. My mom ended up taking her to the vet yesterday and according to her, she was fighting the vets from injecting her and, in turn, putting her to sleep.
My mom was pretty inconsolable today, since she picked her out of the litter we were looking at getting a black lab pup and it ended up being her that watched her be put to sleep. It’s been a pretty sad day.
