What was your measured OG?

Edit: Have you looked through this sticky yet?

You don't have enough base grain to make a 5 gallon batch at 1.040. Where did you get the recipe?

How much water did you start your boil with? How much did you finish with? It does look like the grain bill is a little light, like Blender said.

Edit: I had a question, but found the answer.

Looks like there's a lb grain missing. The specified grains add up to 6 lb not 7, and at 75% efficiency would result in an OG of about 1.032

Your sparging method is going to yield very low efficiency. You don't need a plate on top of the grains. Just add the sparge water and then stir really well before vorlaufing and draining. With a batch sparge, it is this stirring that dissolves the sugars. If you don't stir, you will get low efficiency.

There are only 10 types of people in this world. Those that understand binary, and those that don't.
