I currently do full volume biab brewing. I use an aluminum pot on a propane burner outside. Despite the lack of cold weather in my area it's always a challenge to keep my mash tun, which is my boil pot, a consistent temp. I have a rectangular cooler I can use as my tun instead to keep a more consistent temp. My question is do I need a valve with tubing to transfer the wort to the boil kettle? The cooler I have doesn't have the typical spigot you have to push to let the liquid out. All I have to do is remove the top, see pic below. Is there any concern for hot side aeration? I would assume that once I boil all the oxygen will be evaporated.
If I was doing biab, I would do it in the cooler, remove the bag, then open the drain and jam some tubing on it. If that is too messy for you, just let it fall in the kettle. A healthy vigorous boil and fermentation makes hot side aeration of little concern. There was a podcast with Dr. Charles Bamforth on The Brewing a Network that had good insights on myths and facts of hot side aeration.
I was kinda thinking of something like that. I have gloves so if some of the wort gets on my hands it won't burn them. I could even tilt the cooler a little since I do 3 gallon batches. I'll have to check out the podcast, I love information like that. Thanks!
Check out Brulosophy.com. He does a whole series of experiments to try and debunk "accepted" truths about homebrewing. He did one on hot side aeration.
You can make lot´s of crazy stuff pre-boil. Don´t worry man, brew the hell out of that malt and enjoy your beer.
Thanks for the info. I just read the article and it's a good read. It even mentions Dr. Bamforth's opinion.
