Recently we have introduced a new chiller to our product line. We now carry stainless steel wort chillers. Copper, being the choice of homebrewers in the past, has been increasing in cost over the years. Being that stainless is less conductive than copper, some brewers might be hesitant to give the stainless chillers a try. However, we have done a simple test using both copper and stainless chillers.
In our test, we brought 3 gallons of water to a boil in a 5 gallon pot. Once the water was brought to a boil we immediately started to run cold water through them. We took measurement every 5 minutes to see how well each chiller worked. It ended up taking the stainless chiller 15.5 minutes while the copper chiller took only 13.5. Given the durability of stainless and having the price be quite lower, stainless chillers are not a bad alternative to copper.
