Of course, everything has it's own expiration, but it depends upon on how long you keep it in the fridge. Because the cool atmosphere of fridge cannot prevent the expiration of the beer. From what I have read, Canned Beer, if place in pantry lasts for 6-9 Months, while in the fridge it lasts for 6 months-2 Years. Bottled Beer lasts for, 6-9 Months and 6 months-2 Years, Homemade Beer lasts for 6-9 Months and 6 months-2 Years. Hope it'll help! =)
