Example: Genesee Cream Ale 12-pack cans C146 1301:13 C=March (the third month of the year) 14 (date) 6 (2016) 1 (Rochester, NY brewery) 3 (production line #) 01:13 (hour/minute 1:13AM) Code was on the carton and on the bottom of each can, I figure. Got this info straight from the horse's mouth (I mean Clydesdale's) ... the AB distributor in my area (R. H. Barringer-Greensboro, NC) also has Genesee among its brands. The beer is good for 140 days from the 3/14/16 "born on" date above. Genesee contract brews Narragansett Lager - which I also enjoy - so the codes apply to it, too. P.S.- Harris-Teeter had the Genesee 12-pack for only $6.99 on 5-22.
