Sulfur Sticks are used by some winemakers to treat oak barrels. A portion of the stick is suspended in the barrel and burned before the barrel is put away for storage. In general, we recommend 1/3 to 1/2 of a stick, per 60 gallon barrel. As all sulfur sticks may not be created equal, this equates to 1" by 2" - 3" per 60 gallon barrel. Sold each stick.
