I cannot get rid of a strange metallic smell/taste in the first 3-4oz of any beer that comes out of my taps. Here is what I've done to solve/diagnose the problem:
- Replaced my old Perlick 650ss (known to cause sulfur smells in high acidity beer) with 2019 versions of teh same (supposed to have the smell issues cured)
- Replaced my elbow shank with a version that claimed to be 303ss and 304ss on the elbow part
- inspected my liquid line tubing and found it to be spotless
- I religiously keep my beer line clean with BLC circulated via pump every time I finish a keg
- Sometimes StarSan goes through my beer line if I'm purging a keg that had some left at the bottom
Yesterday, I took a magnet and put it on the shank. Most of the shank was non-magnetic, but the bent tube attracted the magnet. Does the magnetism indicate that the bent tube could not be 304ss or does that grade of stainless have some magnetic property?
Do I need a new shank?
I'm tired of throwing away beer every time I grab a pint!
