On recent brews I've skipped the primary fermenter and have gone directly to the secondary. So far this has turned out just fine. I know people say the secondary is not necessary but I'm skeptical, especially when the primaries are getting washed and I just need to move pre-aging forward into the fermentation/signs of fermentation phase. I use 3 gallon carboys for secondaries. For primaries, I only have a 11 liter glass container which is being cleaned. I am thinking about upgrading my vessels to greater ones so that I can stop using blow off tubes in my secondaries.
