I have spent the last little bit searching the forums and have not really found an answer to this question. I have a cream ale (OG 1.045, not sure of FG yet) that will be done and going into bottles next Sunday. I am going to brew another cream ale that day and thought I would experiment and try to reuse the yeast. I am NOT pitching straight onto the cake--just harvesting whatever Mr. Malty tells me to and then using it in the next batch immediately that same day. So--my question is: do I still have to aerate the wort or is this unnecessary since the yeast have already reproduced? I didn't know if oxidation would be an issue since I was reusing already reproduced yeast. Thanks in advance for the info!!
