I need to make a new Lautering Aperatus as my PVC one has finally gone Kaput(I have only been doing partial Mashes with it in a 48 Qt. Cooler). So, I will be making a new one out of Copper. My question is about the holes that the wort seeps into. Should they be facing up or down? I was thinking maybe have half of them up, and half of them down. What do you think?
