Aluminum Kettle!!

  Contrary to believe, aluminum pot will not cause off flavoring, if properly prepared. In other words the kettle must be oxidized. There are a few ways to oxidize your aluminum kettle. You can fill it up with water and boil it for about an hour or put it in an oven for approximately 45 minutes. What this does is creates a thin grey coating or barrier. This layer is crucial to help protect. DO NOT scrub this layer off! When cleaning use the non abrasive side of the scrubbing pad. Because it is oxidized you can not use cleaning products like oxy clean.
  A plus side to aluminum is it very cost efficient, and is more readily available. You can find one at your local Walmart/Target, for a fraction of the price you would pay for SS. It is a much better conductor of heat. Which means you will be able to boil and cool your wort much faster than stainless steal. My first brew kettle was a Tamale/ seafood steamer. The kettle was 40qt. For approximately $25 at target. Being to to homebrewing I could not afford a SS kettle. I had sever successful brews using an aluminum kettle.
  I feel like I should address some concerns most people have towards aluminum kettles. Aluminum is NOT link to Alzheimer's. A number of studies have been done since the late 70's. They have found zero links between Alzheimer's and aluminum pots. Like most americans, we drink our sodas and beer from aluminum cans.
Aluminum is used by several brewers around the world. Many will agree that brewing craft beer in aluminum kettles is perfectly fine and safe.
