So, a Pennsylvania brewery may stop selling the 16-ounce brewskis.
The 138-year-old Straub Brewery is one of the last in the nation to offer the returnable bottles.
But officials say their losses are mounting because too many customers toss their empties instead of returning them.
Straub and Straub Light are currently sold in the returnable bottles.
The brewery also sells those beers and others in 12-ounce nonreturnable bottles and cans, and kegs of various sizes.
