So, as I order ingredients for my next brew I have come across a question. If I am only doing a 2.5 gallon brew of a 5 gallon recipe, do I need to try and figure out a way to cut the yeast in half as well? If so, do I pour it into a small cup and weigh it and cut the weight in half? Or, can I just pour the whole packet in and let it go from there? Thanks in advance guys, I am hoping to do this over the weekend. RR
