Things are quiet at work today so I did a bit of research.
The scientific article cited in their website as
Science 268, pp. 1060-1064, 1995 is actually titled Revival and identification of bacterial spores in 25- to 40-million-year-old Dominican Amber (RJ Cano and MK Borucki).
The article abstract (to get the whole article you have to pay for it) says:
A bacterial spore was revived, cultured, and identified from the abdominal contents of extinct bees preserved for 25 to 40 million years in buried Dominican amber. Rigorous surface decontamination of the amber and aseptic procedures were used during the recovery of the bacterium. Several lines of evidence indicated that the isolated bacterium was of ancient origin and not an extant contaminant. The characteristic enzymatic, biochemical, and 16S ribosomal DNA profiles indicated that the ancient bacterium is most closely related to extant Bacillus sphaericus.
Wikipedia says Bacillus sphaericus is "an obligate aerobe bacterium used as a larvicide for mosquito control".
The beer web page said these scientists "isolated a few yeast strains that resembled modern Saccharomyces cerevisiae. In other words, they are similar to the yeast we use every day for brewing and baking "
Web page says Saccharomyces cerevisiae (yeast) while scientific article says Bacillus sphaericus (mosquito control).
Also the Peter Hackett Award winning Brewmaster who's quoted on the webpage (yes it's a one page website) as saying the beers' good is actually the brewer who made it!
Sounds like BS to me ...
