Preservative free wine and the use of sulphur dioxide is, however, an expansive and contentious topic and getting to the bottom of it can feel like trying to crack the Da Vinci Code. Preservative free wine is a really a misnomer.

The term âpreservative freeâ is often used to mean that no preservatives have been added during the wine making process.
A preservative is a natural or synthetic ingredient that is added to products such as foods, pharmaceuticals and personal care products to prevent spoilage, whether from microbial growth or undesirable chemical changes.n most cases, preservative ingredients are used to protect the product and help it remain safe and perform as intended over the lifetime of the product. These products are regulated in the US by FDA under the cosmetic previsions of the law and manufacturers must determine that they are safe for consumer use.
