So I recently went with a friend to our LHBS to pick up ingredients for an 10 gallon extract recipe that we will be brewing for Big Brew day on Saturday.
Some of the grain that my friend gathered was not crushed while some was (the LHBS's mill is a little strange and you have to move the rollers on the bottom to get it going). I don't think he noticed it wasn't crushing properly. I didn't notice until I got home when I was putting away the grain that there appeared to be whole grain in the bag. I opened it up and...sure enough there was whole grain along with grain that was crushed.
My question is, can I run the grain through again without compromising the recipe? I know that double crushed grain will extract more flavor/sugars so I am concerned of extracting too much since we are using extract.
