Say I bought an all-grain recipe kit online this past august. I ordered the kit with crushed grains due to the fact that I don't have a mill. The crushed grains came an an airtight bag although it was not vacuum sealed and had some air in it. I didn't get around to brewing it because of a money situation that left me unable to buy/build the appropriate all-grain equipment. Would the grains still be good? Should I at least give it a shot to see how it turns out? It would be my first all-grain brew day and a good practice run for a Citra IPA I have planned. Go or no go? Thanks for the input!
