CLEVELAND, Ohio -- Cleveland's very first micro-brewery is getting very popular around the country, and now it's undergoing a $7 million expansion with the addition of six huge 600-barrel tanks.

Crews were busy Wednesday lifting two of the tanks into the Great Lakes Brewery in Ohio City.

The tanks are the first stage of a two-stage expansion, which will increase beer capacity for the brewery.

"Great Lakes Brewing has been growing double digits year after year, 20 percent growth, and these tanks are an attempt to keep up with demand. New York has been asking for the beer, Boston, Canada and we don't even have to take care of our own backyard which is primarily in the Great Lakes region, " said Patrick Conway, co-owner of Great Lakes Brewing Company.

The second stage of the expansion will be later this month -- four more 600 barrel tanks will be installed in the brewery.

"Christmas Ale is my favorite beer, and it's delicious," said Maureen McCarthy, of Cleveland.

Some people enjoying a beer and burger at the brewery Wednesday saw the tanks being lifted into place.

"I think it's wonderful. I think it's great for Cleveland, everything is working out great for Cleveland,” said McCarthy.

"I love the beer and the fact that they are expanding shows that people have great taste and that great lakes is meeting the demand of the market,” said Mitch Dioia, of Cuyahoga Falls.

Great Lakes Brewing Company, which was founded in 1988, currently serves 13 states plus Washington D.C., and with the capital improvements they can handle making Great Lakes beer for a lot more states.
