I have a beer that I racked too early and it was just full of sulfur. Smelled absolutely fetid. I looked up some solutions and found a tip on a wine making forum that suggested pouring a small glass and stirring the wine with copper. And that if it works to try racking the wine through copper tubing.
Tried the stirring thing and side by side the difference is simply friggin' amazing! The beer stirred with copper tastes and smells exactly as it should. The other smells a little like ass.
I'm blown away, had never heard of this technique. The beer stirred with copper is delicious and completely drinkable, the other I couldn't finish an entire glass. Has anyone else heard of this?
