So about 15-16 months ago I went to brew a beer with some buddies across the Delaware in New Jersey. The homebrew shop there would only sell grain by the pound so I ended up with some excess Amber Malt, Caramel Malt, and Smoked Malt (I tried a smoked gourd Brown Ale... came out pretty poor haha). It's been sitting at room temperature in plastic baggies at my buddies house until now when he dropped it off.
Should I try to brew with it or is that asking for issues?
