Brewed an amber ale (LME based recipe) today, and I don't have a wort chiller. I usually dunk the kettle into the sink filled with ice water and stir. Takes quite a while. This time I filled 2 gallon ziplock bags with water about half way, purged out the air and froze them before hand. After boiling I took the ice bags, submerged them in star san solution for a little over a minute, then dropped them into the kettle. Cooled down to fermentation temp in less than half the time it usually takes doing the ice bath method. Has anyone else tried something like this?
