I've been steadily fermenting Beer/Cider for the past 6 months and I have always strained myself when it comes to aeration. I'm not sure if I am aerating to the right levels but each of my fermentations have worked out fine. Typically my fermentations start within 24 hours.
Am I right to assume...
Please help me identify this equipment and it's value.
I'm looking to find out what they are (make/model if possible) in addition to how much they would be worth?
Thanks in advance!
