Is a copper wort chiller safe?
Copper is used for wort chillers because it is an excellent material for conducting heat. But copper, though a key part of the human diet, can also be toxic in high amounts. As it turns out, copper develops a protective oxide layer through repeated use.
Is a copper or stainless steel wort chiller better?
When it relates to heat exchange, copper is a better conductor of heat over stainless steel. Using a copper immersion chiller will cool your wort faster, produce a better cold break, and halt the isomerization of alpha acids (locking in your hop profile) at a faster rate.
Is copper bad for beer?
In addition, copper levels as low as 3.5 mg/L have been reported to cause symptoms of copper poisoning in humans. Therefore, the levels of copper necessary for successful beer fermentation (i.e., below 0.2 mg/L) do not reach a level that would be toxic to humans.
How do you make a wort chiller?
What Do I Need For A DIY Wort Chiller

- ⅜” to ½” Compression Adapter.
- Copper wire between 18 and 14 gauge.
- ⅜” Silicone Tubing.
- Tube clamps.

How do you use a silver serpent wort chiller?
Simply drop your clean chiller into the kettle a few minutes before the end of the boil and it will be ready to go. Brew with peace of mind like never before. Drop-angle connections keep surprise leaks outside your kettle and away from cooling wort. Ensure secure tubing with proprietary barbed fittings.
Can you make your own wort chiller?
While there are many low-cost options available to purchase, building a DIY wort chiller can be a very fun weekend project. An immersion chiller is a basic heat exchange system. A coil of tubing (typically copper) with cool water flowing through it is immersed into your hot wort.
What is a copper in a brewery?
Today few kettles are actually copper. True, some have a copper cladding to provide an additional polishing chore to the brewer but the basic structure is commonly stainless steel. Physically, the big advantage of copper as a heating surface is high thermal conductivity and a more wettable surface than stainless steel.
Does beer contain copper?
Beer is 90 percent water and consists of soluble fiber and trace amounts of calcium, iron, magnesium, phosphorus, potassium, sodium, zinc, copper, manganese, selenium, fluoride and silicon.
Should you sanitize your wort chiller?
You don’t need to sanitize before putting in the hot wort as the heat from the wort will sanitize. But you should clean it periodically. Also, rinse it well after use.
