Aluminum v. Stainless

[hophead78]

I just had tried a beer from batch #5 (a scottish ale) it carbonated beautifully
but the aroma and taste were definitely not. I was wondering if using a 16qt.
aluminum pot could be to blame. I have the same wash/sanitation practices for every batch. but not sure what went wrong. Any info would be great (because the beer is not.)

1) Aluminum isn't going to do that unless you scrub the ever-loving crap out of it's protective oxide layer

2) Why are you sanitizing your kettle? It's 100% unnecessary since you're going to be heating it well over 180 for an hour? And more importantly, do you use PBW or Oxyclean to clean it before sanitizing? Because that will do damage.

Could you post the recipe and maybe the previous ones to see if there is any difference?

Also:

1) Did you change your brewing water? (i.e. from tap to bottled)

2) What temperatures did your beers ferment at?

aluminum should not leech anything into the beer assuming the pot was oxidied, if you scrub the pot after a batch you can take the oxidation layer off. check this out for more info https://www.homebrewtalk.com/f11/faq-aluminum-pots-boil-kettles-49449/
