I brewed a Oatmeal Stout almost a year ago and still have about 12 bottles left. Haven't drank any in about 4 Months. How long will it keep at room Temp in glass bottles. I have never kept a beer this long. But i have been drinking a IPA that i brewed. Just wondering is this Stout still good and if so how long will it keep. Room temp have been from 65-70 F
