Plastics are a very controversial issue, and it is unlikely that we'll have a clear consensus on longterm safety anytime soon. Some plastics are unambiguously unfit for food use (especially at high temperatures), while others are likely fine. Generally speaking, the safest plastic container for no chill brewing would be a HDPE without plasticizers. If you ...

Regular Polypropylene will release mild to moderate toxins at high temperatures. While Polypropylene (PP) is food-grade safe at room temperatures, and commonly used for containers (arguably safe for chilled wort according to comments in the previous link), the Energy Working Group gives it a "low" rating for overall hazard. My recommendation, don't use it ...

I can't comment on the safety of the material, but I can say that No Chilling does not really work if you try to drop the wort temps down before adding the liquid. When the wort goes into the tank, it is the fact that the wort is very close to 100C/212F that guarantees against infection while its sealed. The super-hot wort does a wet pasteurization of all ...

It comes down to your sanitation and process. You want to be filling those cubes hot. This means above 190ºF. This will, to a significant degree, sanitize the inside of the container and ensure that you'll be able to store it for a reasonable period of time. Many no chill brewers go for weeks or even months before pitching yeast.

The downsides as far as I can see are (in descending order of severity) 1) Possible toxicity of the plastic. 2) Recipe alterations due to the continued elevated temps after the boil is over. 3) Risk for contamination. Right now, the current thinking is that "food safe", "heat resistant" HDPE plastics are OK for No Chilling. I am personally content enough ...

The benefit is that you don't have to chill the wort with an immersion chiller or cold bath. You can set it in the cube and leave it to reach pitching temp. The downside is that you have another vessel to clean and some people worry about the effect of not chilling your wort. Most people like the effect of cold break, but this is a new method so it's bound ...
