A typical range is 50-100 ppm (parts per million) of free sulfur dioxide (SO2) at the time of crushing, and around 30-50 ppm before bottling. You should use a sulfite testing kit to measure and adjust the sulfite levels accurately. How much sulfite do I add to my crush? For grapes at the crush stage, you might add around 50-100 ppm of free SO2.

Wine pH has a direct input on your sulfur dioxide content, according to Perry. Free sulfur dioxide is a function of pH. A red wine at a pH of 3.2 requires 15 ppm of free sulfur dioxide added to achieve its targeted 0.6mg/liter of molecular sulfur. The same red wine at a pH of 3.5 requires 30 ppm of free sulfur dioxide to reach the target.

equipment were evaluated. Up to 80 per cent sulfur dioxide removal was feasible. The consumption of limestone ranged between 20 and 30 per cent more than the stoichiometric requirements. Limestone is a naturally occurring calcium carbonate rock which can react with sulfur dioxide. Limestone can therefore be used for desulfurization of flue gases.
