(FRANKENMUTH) -- What else is there to say but "prost" when Frankenmuth Brewery celebrates its 150th anniversary and offers up a limited-edition dark beer for the occasion? The German toast is welcome Monday, when the brewery in the Bavarian-themed Saginaw County community bottles Frankenmuth Dark. The brew includes some of a 50-year-old batch of the beer that originated in the 1940's. The brewery says it will file and number 1,862 bottles to commemorate its founding year. Some will be sold at the brewery starting Tuesday and the remaining bottles will be available at retailers early next month. The Frankenmuth Brewery was established in 1862. It was destroyed by a tornado in 1996, reopened in 2002 and was closed again in 2006. The brewery was bought in 2009 and reopened the same year.
