Would repeated filling and draining with a solution of potassium metabisulphite and citric acid do the trick? I'm hoping that keeping the barrel full of this solution, replacing it twice a week, I might be able to get the barrel neutral in 3 weeks or so. You think that's realistic? I've found a lot of sources for maintaining and properly caring for barrels, but nothing really on intentionally speeding up the time for a barrel to become neutral - I've only read of warnings that using solutions like the one above will extract the flavors out of it, but they always seem to assume that this is undesirable, and so don't exactly outline a methodical approach to doing it![]()
This would work, people store their barrels with a citric acid or Potassium Mets solution. I think it will clean up in a decent amount of time if you use it for the stout then add the solution after.
