I have been reading around on here and once again there seems to be a large dichotomy. I make 3-4 gallon batches and use a 7 gallon plastic bucket as my primary. I usually rack to a secondary but i no longer feel that is necessary for certain styles. Am i able to leave that 3-4 gallons in the 7 gallon bucket for the entire fermenting process (3 weeks) without imparting any off flavors? i dont open until i am ready to siphon.
