The first brewery in Georgetown is expanding.

Rentsch Brewery has been open a little more than a year and is working in overdrive to keep up with demand.

Right now, you can find Rentsch Brewery beer at their tap room or on draft at some Williamson County restaurants.

But with this expansion, you'll also be able to find it in a can at your local convenience store.

Co-founder Andrew Rentschler wanted to open the craft beer brewery in his hometown, Georgetown.

"When we opened there was nothing anywhere near us,” said Rentschler.

With the closest brewery in Austin, Rentschler said they sold everything they had on the grand opening.

"The turnout was just way more than we ever expected,” said Rentschler.

Since then the momentum hasn't stopped.

"We're running our brewhouse constantly, pumping out as much beer as we can and it's still just not enough,” said Rentschler.

For Rentschler, the idea formed at this table with his dad in Switzlerland while studying abroad. He then taught himself how to brew.

"I pretty much moonlighted buying all the textbooks I could find on brewing,” said Rentschler.

Now, Rentsch Brewery is expanding, both the building and business.

"We're to the point where we can't fit any more tanks where we are now," said Rentschler.

Rentchler said they'll go from making about 1,000 barrels a year to 10,000.

They're building a new tap room and biergarten.

"It's going to have a Texas Hill Country Vibe with a bunch of reclaimed wood,” said Rentschler.

And, they'll go green by using a rare electric boiler to power the operation, when the city switches to solar and wind energy next year.

"We're going to be within a handful of breweries in the world that are actually 100 percent renewable energy power,” said Rentschler.

They plan to finish the expansion in the spring and start selling cans in local stores soon after.
