So I am a new brewer and have a 6.5 gallon carboy, and I think a 7 gallon bucket. Not knowing that I would have to use yeast starters to up the yeast in order to ferment these bigger batch sizes I tried to go for larger tanks than the standard five gallon. As I am not an electrical expert and my building of my yeast stir plate to compliment a yeast starter is slowed until I can figure out how to use the wire connectors. I am not Bob Vila but I hope to be one day. My question is if I ferment a five gallon batch in these larger vessels are there many downsides? I have heard it will affect the beer and taste. Any thoughts?
