First Sam Adams beers brewed in Latrobe

The brewing kettles at the former Rolling Rock brewery in Latrobe swung back into production Monday with the first batch of Samuel Adams beers that will be made under contract by City Brewery.

Boston Beer Co., brewer of Samuel Adams beers, signed a deal with plant owner City Brewing Co. in April to brew its products. Boston Beer said it planned to invest $3 million to $7 million to upgrade the plant in Latrobe, Westmoreland County, to accomodate its brewing processes, proprietary yeasts and extended aging time of its beer.

The plant expects to produce about 200,000 to 250,000 barrels of Samuel Adams beer through the rest of this year.
