Hi everyone! Im trying to decide between a 1 vessel E BIAB and a 3 Vessel EHerms or Rims system. Reading the reviews on EBIAB it seems that brewdays are generally quicker and more efficient. Giving a rough estimate how long is a brewday on each system? Additionally, is brewing on a 3 v herms/rims more difficult/ require more skill than a 1 v system?
