hi guys, ive got myself 4 one gallon demi johns and my plan is to brew 4 different types of the same style of beer at once, eg 4 wheat beers, 4 lagers and so on. this is so i wont waste any yeast. my question is would it be ok to hydrate one packet of yeast and then divide the mix evenly between the four demi johns ? has anyone done this before or have any advice on the subject ? cheers guys
