Hello all, What advice do you have on chilling wort on a 1-gallon batch? I brewed my second beer and really hate how long it takes to cool wort with an ice bath. I know I can get a wort-chiller but is it worth it for use on 1-gallon batches? I don't plan on upgrading to 5-gallon batches anytime soon; I like the idea of small batch brewing and being able to brew more frequently. How can I speed up my wort chilling process?
Use a sanitized spoon to continuously stir the wort and create a whirlpool in your brew pot. That puts more of the wort in contact with the side of the pot for better heat exchange.
I'd just submerge the outside of the kettle in a sink filled with cool water. Stir the wort with a sanitized brew spoon. When the sink water gets warm, pull the plug, and refill with cool water. Once you get the wort down to 100F ish you can start using ice to bring the temp down even quicker and to a temperature more acceptable for pitching yeast. If you have two sides to your sink you can fill one side about halfway with ice while you are working with the other side of the sink to bring the wort down to 100F. You could use frozen two liters for your ice. Easy to reuse, but they don't have much surface area. I usually fill my automatic ice cube dish with water and make a block of ice the week before. I make two or three of these. I take them ouside and drop them on the asphalt. I have tons of ice chips that will melt quickly. Pitch your yeast to your fermenter, add your wort from your kettle, and smile. Edit: An alternative, since you are working with small batches, would be to work out of the bath tub. You can get a lot of water and a lot of ice going this way. 1 gallon of boiling hot wort is a lot safer to carry than 5 gallons, IMHO. Stairs are still a no-no.
Thanks for the response fellas. I will def incorporate these on my next brew day; so as long as the stir is slow, I don't risk contamination? (especially with the wort still at a fairly high temperature?)
The inside of your brew pot should be sterile from the boil. My setup is brewing full-boil 5 gallon batches in a 10 gallon pot and use a copper wort chiller - but the concept is the same. The faster/more you stir, the faster the temperature drops.
Here's a link to a recent thread that might give you some ideas. I think it centered on 1-gallon batches. http://www.beeradvocate.com/community/threads/chilling-wort-best-practice.377074/#post-4429567
Anything over 160 is pasteurized, as far as I'm concerned. Most microbes we are working with, or against, in brewing are killed off at 130.
