I'm constantly checking bottling dates on stuff when I buy beer, post the freshest you've seen and where. Feel free to shame old beer on shelves as well. Wookey jack - bottled 9-10-13 - whole foods arbor trails Dogfish 90 min - bottled 9-5-13 - world market Brodie (60 min 8-29 too)
Central Market Westgate had Sculpin & Big Eye cans that are less than 2 weeks old (I wanna say 10 days old as of now)
