Sulfur dioxide addition to must

Abstract

A system and process for relatively quickly applying and evenly distributing accurate amounts of sulfur dioxide to must. The system comprises a sulfur dioxide containment vessel and means for pressurizing the sulfur dioxide in the vessel with an inert gas. Conduit means delivers the sulfur dioxide to a must flow conduit. An inert gas under relatively low pressure is introduced into the conduit for the sulfur dioxide conduit means for ultimate delivery to the must flow conduit. Metering means delivers the precise proportions of sulfur dioxide to the must flow conduit. The process enables the introduction of precise proportions of the sulfur dioxide to the must flow conduit and the introduction of an inert gas under relatively low pressure along with the sulfur dioxide into the must. In addition to the accurate delivery of sulfur dioxide to the must, the back flow of juice from the must is prevented when the supply of sulfur dioxide is stopped as a result of the continuous flow of the relatively low pressure inert gas into the must flow conduit.
