Copper is also antimicrobial and doesn't form slime easily. There isn't a lot of research on the relationship between copper and beer-related microbes, but it is a common metal for fermenters.

So basically SS IC's are garbage?
Or should I say inferior?

No, that's nonsense. Copper tends to be a little cheaper than SS and easier to work with, hence all the copper chillers.

Also, soaking your chiller in your Star San bucket can only help. I do that and then plunk it in the hot wort.

No. They are certainly not garbage and I don't think inferior. I find it very hard to believe that an equivalent surface area of ss vs copper will do an inferior job. The tube walls are only 1/16" thick. The heat transfer is good with both.

As far as anti microbial, I'm not sure how different the two materials are. Basically, what you want is a hard, non-porous material, which they both are.

If someone can show me legitimate results showing that a copper IC works better than a ss IC, I'll eat my hat. I'm guessing people know that copper transfers heat better, so they think it works better, and take anecdotal evidence as gospel. I've never known of someone being dissatisfied with a ss chiller and being thrilled with their new copper chiller.

My two cents.

I'm no metalurgist but the main reason most ics are copper is because its/was cheaper and easier to work with. I built my own a few years ago for about 20 bucks, was super easy to coil it around, don't think i would've had such an easy time with ss.

First a fore most, always take teh time to clean your equipment. Second, it is hard for bacteria to grow on metalic surfaces, especialy copper. I normaly dip SS wort chiller in saitize, star san, to give it a quick cleaning and a rinse. Then i just stick the chiller into the kettle and begin cooling. I never boil it or do anything special as once it hits the wort it is pretty much instantly sanitized.

The difference between SS and Copper as far as cooling time is probably negligible. They can make the SS ones thinner because steel is stronger, and the thinner metal makes up for the difference. I recently cooled 3 gallons from boiling to 63 degrees in 10 minutes using stainless (granted it was 35 degrees outside and the ground water in Michigan this time of year is pretty cold).

I am very happy with my SS IC. Also, as far as I know you can't use StarSan on copper (it will dissolve it), not a problem with a stainless chiller. Not really necessary, as others have said you can just put it in the boil, but I think it's nice to be able to give it a quick dunk if you don't think to put it in the pot in time.

Bottom line: keep it clean. Don't get bent out of shape about it.

I'm not sure how true that statement is. I ended up getting a SS immersion chiller because it was 25 bucks cheaper than a comparable copper one.
