HSA - Hot Side Aeration, is considered more a myth according to many people on this forum.

Aeration is supposed to be done right before you pitch your yeast which does not necessarily right after it is cooled. Yeast need oxygen to reproduce and do their job but once they get full and tired the oxygen will hurt your finished beer.

As far as DMS being produced, there have been a few side by side tests done of no chill vs fast chilling and all them concluded that it is not an issue. Aside from the "Brew Your Own" episode(s?) on it, a few people in the "Exploring No Chill" thread that I mentioned have tried it themselves and come to the same conclusion.

No chill is highly utilized in Australia due to their strict water restrictions and more and more people in the states are doing it as well.

Keep in mind, if you use your BK to no chill in then you should not use your ball valve to fill your fermenters the next day because it will not be sanitized.

I have not experienced any infections since I have been brewing, and I literally have done no chill method every brew. The brew pot is sanitized form the boil procedure and I have a lid that I keep sanitized that fits snugly on top. With safe and sanitized practices I believe there is little chance for infection. My wort is no more aerated than when racking when it's cool either....

I did mess around with an immersion chiller but it really did seem like a waste of water when I can just let the wort sit. Especially if you are brewing 10 gallon batches ever two weeks or even more often.... that water can add up lol However at some point in the future I do plan on buying a plate chiller to add to my setup and those I do recommend using.

Water is expensive here in Chicago. (Yes, I know, we're right next to one of the largest bodies of fresh water on earth. Remember, it's Chicago).

"Wasting" an extra 20 gallons adds up quickly. Building a rain barrel for the garden and recycling brewing water cut my water bill by 75%. No false sense of economy here.

Thanks for the tips. Slipgate, water is a commodity and can be conserved, you are false for thinking otherwise (see TyTanium's post above). I know yeast needs oxygen guys.

If the water goes down a city sewer, it is recycled. According to Chicago water rates, 1000 gallons costs $2.51 + 89% of that for sewer. That is roughly 9 cents for 20 gallons. Probably the cheapest part of your brew day. As you pointed out, you are next to one of the largest freshwater bodies in the world, so there is no shortage of water.

But I get your drift.

It's not the usage rates that kill you, it's the taxes.

HSA is not a concern when transferring hot wort into a carboy since the carboy is going to explode and the wort will be all over the floor.

In the summer, I run the water into a wading pool for the dogs. Otherwise, it goes into the septic tank and out into the drain field where it eventually hits the "timber line". That's out at the retirement house.

Our main home, they don't charge for water. In the winter they check the meters and use that as a basis for sewer fees, but it's the same year-round.

Few ways to decrease your usage during brewing other than no chill. The only other ways I can think of are to clean more efficiently with less water and make sure your chilling is very efficient. You can reuse the otherwise wasted water in lots of ways.

Use an old carboy to reuse your star san(it doesnt go bad)
hook a sprinkler up to the end of your chiller out hose and water the lawn
use the chiller water for laundry
use the chiller water to clean your equipment

I think it's admirable to want to conserve regardless of incremental cost. When you think about how we (myself included) use potable water, it is a bit ridiculous: flushing the toilet is the biggest WTF I can think of. Running potable water through an immersion chiller is wasteful also.

I don't want to start any socio-political arguments here, but Americans use an obscene amount of potable water per capita than most countries.
