So I finially bought my first used bourbon oak barrel for aging beer.
It seems that each place I look for information on barrel sanitizing has a different recommendation.
I am sure there are different techniques for new vs used barrels.
For my used oak barrel i followed these instructions:
1) sulfur strip
2) Barolkleen 3 ounces per gallon hot soak for one hour, rinse well
3) sodiummetabisulfite 2 grams per liter plus citric acid one gram per liter, hot soak for 30 minutes, rinse well
4) rack the beer!
Any suggestions, improvements?
Also, can I save and reuse the Barolkeen for the next few barrels?
