Saranac

The historic F.X. Matt Brewery, maker of the popular Saranac line of beers, is getting more "green" next month.

It won't be making green beer on a regular basis, as some brewers do for St. Patrick's Day, but it will flip the switch on a new anaerobic digester.

Nick Matt ducks into side doors and up staircases while rattling off the history of the F.X. Matt Brewery in Utica.

The brew house is like a second home to Matt because it was his grandfather, F.X., who first opened the brewery 124 years ago.

If you're racking your brain to see if you've ever heard of F.X. Matt Brewery, try this: they make Saranac ales and lagers. For the older generations, does Utica Club ring a bell?

Five big new tanks have arrived at the F.X. Matt Brewing Company in Utica. But they won't be used to make the brewery's signature Saranac brand craft beer.

Instead, the tanks will act as anaerobic digesters for the brewery's wastewater.

Special bacteria will munch on the yeast and grains left floating around. The process will get the water about 85 percent cleaner before it's discharged into the sewer system, according to CEO Nick Matt.

But the digestion process also gives off methane gas and carbon dioxide.

That methane will be used to power a generator. CEO Matt says the new system will cover up to 40 percent of the brewery's electricity needs.
