Abstract
A system and method for dosing SO2 into wine barrels is achieved with a device including a compressed gas cylinder containing compressed liquefied SO2 under its own vapor pressure, a dosing wand fluidly connected to the cylinder via a hose that is adapted and configured to allow a flow of gaseous SO2 from the source to the dosing wand. The dosing wand includes a hollow needle dispensing nozzle and a SO2 batch flow controller in fluid communication between the hose and the hollow needle. The hollow needle dispensing nozzle is adapted and configured to pierce through a bung opening of a wine barrel and has at least one aperture at a terminal end thereof to allow gaseous SO2 to be dispensed into an interior of the wine barrel.
