Diy Parallel Counterflow Wort Chiller. For temperature the plate chiller is simplistic. I brew mostly hoppy beers with big late and whirlpool additions.
I had an immersion chiller but once i built the counterflow is just collects dust. It is a bit of a sore subject, but i will discuss it now in hopes nobody repeats my mistakes! A heat exchanger can have several different flow patterns.
I have a question though.
The water connections are male and female 3/4 hose connections. I chose to use 1/2″ copper tubing fittings to make the ends, similar to other designs i’ve seen. This is much quicker than when i was using (and agitiating) an immersion chiller. So if you're not using a wort chiller, i highly recommend you make your own.
