OLD label KBS dating help needed

Bottom of the bottle? That may be a code for the bottle itself. I reckon that the code should be stamped on the neck of the bottle.

 

Pictures, pictures, pictures!

 

After perusing many reviews of it around that time period and not reading any mentions of dating, other than the odd new release, I have to reckon that they weren't dated.

 

I agree with @Bitterbill, the stamped code on the base of the bottle is more than likely the bottle manufacturer's code. Pretty unusual for a brewer to stamp filled bottles on the base (unlike cans)- not saying it couldn't happen, though.

Because of the angle of the photo, can't make out the embossed digits but an "SG" embossed around the bottom of the bottle, would signify it was made by Saint-Gobain (later known as Verallia North America) - at least, the older Founders bottles I have are SG's. If there's a anchor shape, it was manufactured by Anchor Glass. "O-I" is Owens-Illinois.

Typically the bottle manfacturers' embossed characters, either on the base (like in the pic) or around the bottom will include a two-digit year. Looking at the stamped code in your OP I'd guess the bottle was made in 2007 - if there's an "07" embossed as well, that would be back that up.

 

From reading this I am not sure if you could see it, but there is an inked stamp of some set of numbers on the bottom. -Not just embossed letters/numbers.

 

Yeah, that's what I wrote, and differentiated the two:

US Glass bottle manufacturers' molds typically emboss various letters, numbers (usually including a 2 digit year) and, often, their logos/initials into the bottle, around the bottom and/or into the base. In addition, they ink or otherwise stamp a code on the base or near the bottom of the bottle (usually around or below where the label ends) with mfg. info which includes the actual day, time, shift, line, mold, etc, for the specific bottle.
