BEER MADE WITH 45 MILLION YEAR OLD YEAST

Shades of JURASSIC PARK!!!  At the face this is just fascinating, and shows just how tenacious life is.  But I cannot help but wonder if a bacteria that could be extremely harmful could also be activated.   As that great Greek philosopher Anonymous, said thousands of years ago.  "Just because you are paranoid, does not mean they are not out to get you."

PREHISTORIC YEAST REBORN IN MODERN BEER

Sept. 23, 2008, Discovery News Channel -- Trapped inside a Lebanese weevil covered in ancient Burmese  amber, a tiny colony of bacteria and yeast has lain dormant for up to 45 million years. A decade ago Raul Cano, now a scientist at the California Polytechnic State University, drilled a tiny hole into the amber and extracted more than 2,000 different kinds of microscopic creatures.

Activating the ancient yeast, Cano now brews barrels (not bottles) of pale ale and German wheat beer through the Fossil Fuels Brewing Company.

"You can always buy brewing yeast, and your product will be based on the brewmaster's recipes," said Cano. "Our yeast has a double angle: We have yeast no one else has and our own beer recipes."

The beer has received good reviews at the Russian River Beer Festival and from other reviewers. The Oakland Tribune beer critic, William Brand, says the beer has "a wierd spiciness at the finish," and The Washington Post said the beer was "smooth and spicy."

Part of that taste comes from the yeast's unique metabolism. "The ancient yeast is restricted to a narrow band of carbohydrates, unlike more modern yeasts, which can consume just about any kind of sugar," said Cano.

Eventually the yeast will likely evolve the ability to eat other sugars, which could change the taste of the beer. Cano plans to keep a batch of the original yeast to keep the beer true to form.

If this has a ring of deju-vu, it could be because Cano's amber-drilling technique is the same one popularized in the movie Jurassic Park, where scientists extracted ancient dinosaur DNA from the bellies of blood-sucking insects trapped in fossilized tree sap.

Cano's original goal was to find ancient microscopic creatures that might have some kind of medical value, particularly pharmaceutical drugs.

While that particular avenue of research didn't yield significant results, the larger question of how microscopic creatures survived for millions of years could help scientists understand certain diseases, said Charles Greenblatt, a scientist at Hebrew University in Jerusalem who studies ancient bacteria.

"We've got cases of guys who contracted [tuberculosis] during World War II and lived with it for 60, 70 years," said Greenblatt. "Then suddenly they get another disease, the TB wakes up from its dormancy and kills them."

Inducing dormancy could be a new way to fight disease and infection, said Greenblatt. Instead of outright killing infectious creatures, doctors could instead put them to sleep. The infection would still be present in the patient's body, but it wouldn't hurt the patient.

Neither Cano nor Greenblatt can say what the upper limit for hibernating yeast or bacteria is; it could be hundreds of million years. But while other scientists work on that, Cano plans to spend his time tossing back a few cold ones, and hoping others will too.

"We think that people will drink one beer out of curiosity," said Cano. "But if the beer does taste good no one will drink a second."
