Sierra Nevada to make ethanol from its leftover yeast

My fave brewery by far. A SNPA was the first real beer I every drank. Good ol 1056 American ale yeast is the one I used most often. Little known secret: Crane River used 1055 which is a better flocculating version.

Currently, production waste is sold as dairy feed to local farmlands. In fact, Sierra Nevada sells 1.6 million gallons of beer yeast waste annually. But not once this system is in place. Testing will start in Q2 of this year with a goal of full-production by q3.

The beer yeast contains between five and eight-percent alcohol content, but the MicroFueler is expected to raise the level to 15-percent.

“Creating ethanol from discarded organic waste is an excellent example of how the MicroFueler can help eliminate our reliance on the oil industry infrastructure. This is especially true when considering Americans reportedly discard 50% of all agricultural farmed products,” said Tom Quinn, E-Fuel founder and CEO. “Using a waste product to fuel your car is friendlier to the environment and lighter on your wallet, easily beating prices at the gas pump.”

Of course, Sierra Nevada has a history of being a bit eco-friendly: they are home to one of the largest private solar installations in the US.
