The brewer of Samuel Adams beer is recalling selected bottles of beer that may contain tiny bits of glass.

Boston Beer Co. said Monday that the recall comes after routine inspections at a company brewery in Cincinnati found defects in 12-ounce beer bottles made by a third-party supplier. Inspectors discovered that grains or bits of glass could break off and possibly fall into the bottle.

Fewer than one in 100 of the bottles from the Cincinnati plant are believed to be defective.

The Sam Adams beers affected by the recall have a special marking on the base of the bottle. The marking has the letter "N" followed by the number 35, followed by the letters "OI."

Boston Beer says there are no reports of any injuries to consumers.
