Sometimes I give IPAs a 30 minute hop stand. Most beers get chilled immediately after I turn the burner off. Depending on the time of year, it takes anywhere from 15-25 minutes to chill down to pitching temps. Lagers are a different story, however, I was able to chill a vienna lager down to 50F in 20 or 25 minutes last Saturday. The tap water is really cold right now. That was great. I might have to buy a pump to recirculate ice water for the summer months.
