Here’s the deal on the letters at the bottom of Shiner beer bottles: this is a production code stamped on by the bottle manufacturer. The “DIE” is actually “DI3” read backwards through the glass. The “D” indicates the fourth tank at the production facility; the “I” indicates the first production line on the “D” tank; and the “3” indicates the time the bottle went through the line, i.e., 3 a.m. All bottles which go through this particular production line every day between the hours of 3 a.m. and 4 a.m. are stamped with the “DI3” code. The “DI3” code is preceded by a Julian date code which specifies the date the bottle was manufactured.
We assure you that there is nothing malicious about these codes in any way.
