First of all, I have never done this before. I have been homebrewing for 3 years and decided to start harvesting and reusing yeast. My first attempt will be a lager yeast. I read numerus posting on here, but I feel like I am missing something. I went to Mrmalty and it says to re-pitch a 5.25 gallon batch lager with OG of 1.048, on a relatively thick yeast, I will need around 110ML of yeast cake. This is half a mason jar (the half pint). This seems like a ton of yeast considering my dumps produce a small 1/8 to 1/4 inch layer. Is this right? I know it takes much more lager yeast than ale, but this would take me like 5 dumps just to get 1/2 that amount. I think this is also assuming no starter. Any help is appreciated.
