In Denny We Trust.
I brewed today, did a 60 minute boil and hop additions. I used my JaDeD Hydra and got my wort down to around 75°. I then transferred it to a plastic brew bucket, sealed tit up and put it in my ferment chamber, When it gets down to about 60°, I will pitch the Gigayeast.
I used the Hydra and chilled the wort because my bucket is rated for 170°, I figured I will chill it down to what is easy to archive. My city water makes 75° the point of diminishing returns kick in.
I did not literally seal up the bucket. I used a hunk of 1.5" PVC pipe. I got a cap and and drilled for a hose barb stuck on one end of the pipe. Next I stuffed a bacteria barrier stopper in the pipe. A hose goes from the barb to a drilled stopper. I have a couple screws in the open end to keep the stopper in place. There will plenty of ventilation for the wort to contract.
