I was watching a Youtube video regarding procedures for chilling wort post-boil. The guy was tossing snow and ice directly into his kettle, which I thought was hilarious for obvious reasons. Then I started thinking that it might be possible to chill wort by adding sanitized bottles of frozen H2O. Just toss 'em into the kettle. Clarity is an issue that I have not had much success. Conversely, I can make great tasting beer. I'm going to try the above procedure on an Irish Red. It's hard to knock down a boil during the summer.
