- Are you using an auto siphon to transfer between boil pot and fermentation chamber - or are you priming the transfer tube with your lips?
- How clean is your carboy REALLY?
- How long are your boils?
That's just a start - but if you can answer those I'm sure the crew here will be really good at ferreting out what could be going wrong in the process. Good job on the Star-San - but it's gonna have to be used properly - so explaining your methodology there will help as well as your routine for cleaning (contact time with cleaners and agents and mix of the solutions).
Somewhere out there is an answer. Have you dropped cinnamon sticks onto all of these batches?
I'll try to go into as much detail as I can. Firstly, I brew based off the instructions that come with the Midwest Supplies kit.
I start by scrubbing the boiling pot in the sink, soap and water. Then fill with pure clean water from the tap and let that start boiling.
Then I take the primary bucket into the bath tub (as that's the only faucet I have that can fill it) and begin scrubbing with Oxi. I throw the airlock and thermometer into the bucket to soak for a bit. I wash and rinse those pieces and the lid. I also have a "paint stirrer" that attaches to my drill that I use just before I pitch the yeast to get some extra oxygen into the wort. I wash and sanitize this at the same time.
Then I brew. I use a wood or plastic spoon. I just wash that and sanitize it in the boiling water.
Then I poor the wort into the primary bucket, stir with the drill attachment, pitch yeast, place it in the closet with the air lock on the lid.
Clean everything and put it all away.
8 days later (tonight) I transferred to the secondary. I clean/sanitize the exact same way. I have a bucket that I can fill to soak everything like my pump and tubing.
I still have a sneaking suspicion that it's going to turn out well. So I'm going to go ahead and bottle just to see what happens.
