Looking to brew my first all grain. I don't have the kettle volume so I am using beersmith to scale recipe. It is telling me to use .6 packs of yeast. Is there a detriment to using the whole pack that will affect the beer? I don't want to store the remaining yeast if I only use .6 of the pack as I don't see a day I will need .4 of a pack. Should I just use the whole pack or actual try to measure .6 of a liquid yeast pack?
