In a surprising development in the world of brewing, Fossil Fuels Brewing Company from the San Francisco Bay Area has demonstrated that it is indeed possible to make beer using ancient yeast. Dubbed the "45 Million Saison," this unique brew utilizes yeast extracted from a 45-million-year-old amber fossil containing a bee, a feat made possible by microbiologist Dr. Raul Cano, who first revived the yeast in 1995.

Despite initial skepticism, the revived yeast proved viable for brewing. Ian Schuster of Schubros Brewery collaborated with Dr. Cano and others to create what they called the world’s oldest beer. The resulting saison has an amber hue, a lively fizz, and a nuanced flavor profile with hints of grapefruit.

The brewing process began with finding the right yeast, which required careful consideration and several attempts before they found a suitable candidate. Their choice to brew a saison not only highlights the yeast’s unique characteristics but also inspired the beer’s catchy name, referencing its ancient origins and perhaps paying homage to popular culture.

However, while the beer gained attention and even raised funds through an Indiegogo campaign, the Fossil Fuels Brewing Company has since closed its doors and is no longer producing this extraordinary beer. Those interested can still hunt down limited stock at select online retailers.

For beer enthusiasts looking for other ancient options, Lost Rhino Brewing Company utilizes yeast from a 35-million-year-old whale bone in their Bone Dusters Paleo Ale. Additionally, brewers like Dylan McDonnell are experimenting with ancient yeast, including some that is 3,000 years old. Those eager to recreate a taste of history can even brew their own version of Pharaoh Ale at home, inspired by ancient Egyptian techniques.
