Northern Brewer Stainless Steel Counterflow Wort Chiller Review

This is a personal product review of the Northern Brewer Stainless Steel Counterflow Wort Chiller. I was able to capture a performance of chilling 6 gallons of water from boiling to 67 degF in 20 minutes!
You can find the chiller for sale over at Amazon: a.co/d/37ASxTr
I personally bought this product, and have no affiliation with Northern Brewer. The opinions in this video are my own.

Thanks for the review. I would find it interesting to see what you could do in a single pass. That is, restrict the wort flow down to the point where the exit temp is ~70F. If that is something like .5 gallons per minute, you could transfer 6 gal in 12 minutes. The down side is that the kettle remains hot for those 12 minutes (if you are concerned about DMS).

Hopefully, you know by now that that is not how one uses a counterflow chiller. The goal of a counterflow chiller is to drop the temperature of the wort to that of the incoming water supply in one pass. What you demonstrated here is very misleading. You have basically turned a counterflow chiller into a glorified immersion chiller. The wort is only recycled to the kettle through the chiller long enough to ensure that the chiller is truly sanitary. That step is performed with the cooling water off. It takes less than a minute of recycling to achieve pasteurization temperature when wort is near boiling temperature. After a minute or two of recycling, the output from the chiller is directed to one’s fermenter and the flows of the incoming water supply and the outgoing wort are adjusted such that the outgoing wort is close to the incoming water temperature and the outgoing water is close to the temperature of the incoming wort. That maximizes heat exchange, resulting in a significant reduction in cooling water consumption.
By the way, the brewing term “wort” is pronounced wert, not wart.
