For about 1/2 of the wort transfer from the mash tun to the boil kettle it was splashing pretty badly. Is this going to screw up the beer? I now have it running down the side of the brew pot. Is that an OK method? Thanks.

I tend to think that hot side aeration is a myth. Some people think that if you splash while the wort is hot, then you'll get off flavors. I've splashed plenty in the past, and never noticed anything bad from doing so. I try to keep it down though, just in case.

HSA/splashing issues are another myth for the homebrewer, that new brewer's tend to worry about (like airlock bubbling = fermentation),that don't really hold much weight in truth, you really don't need to worry about it.

Here's a detailed post explaining why it's not an issue, including a video of a commercial brewery doing the exact same thing... http://www.homebrewtalk.com/f39/stir...6/#post2358507

There's also a really good discussion of it in the article on Australian No Chill brewing in the March/April 2009 issue of BYO magazine where there is an excellent citation proving that boil and fermentation further eliminates the risk of hot side aeration. I'm waiting form them to post the article so I don't have to retype the citation. But as soon as I can it will go with the other information I have posted.

I also have never exp. any negative effects from splashing. I did buy a piece of that super high temp hose that the brew shops sell to eliminate the splashing just in case. It can't hurt and only cost a few bucks.

Thanks for the help and reply. I really do appreciate what you offer here... although I still disagree about the airlock

Cold liquids can hold more dissolved gases (oxygen) than hot. Even if you did manage to get some more O2 dissolved in your hot wort splashing it around, the boil process would cause all of it to come out of solution anyway. I may be new to brewing but that is just chemistry, which I do have experience with.

This is my thought exactly. It may or may not be an issue, but silicone tubing is cheap, so why take the risk?

I know Brew Strong did a great interview with Charles Bamforth about oxidation. He said while you aren't going to see any effects (esp in homebrew) from splashing wort etc, its always good to follow best practices like avoiding splashing when possible, not whipping air into the mash and so forth. Its much more important to keep splashing and aeration to a minimum after fermentation has begun and has finished though.

I think the point is here there isn't any risk to start with....

I would tend to agree with Charles Bamforth, one of the leading brewing scientist in the world, as opposed to the people on this forum, but that's just me.

I just don't understand why someone would take the risk when the solution to the problem is so simple and cheap.
