Puro 5

5% solution of sulfur dioxide in water for sulfitation of musts and wines.
Technical sheet
Safety data sheet
Puro 5 is a 5% solution of sulfur dioxide in water used for sulfiting musts and wines. Sulfitation is a common process in wine production in which sulfur dioxide (SO2) is added to must or wine. Sulfur dioxide is a widely used wine preservative that performs several functions, including:

  • Antioxidant: prevents unwanted oxidation of wine, helping to maintain its aromas and color.
  • Antimicrobial: helps control the growth of unwanted microorganisms, such as bacteria and wild yeasts, that could cause defects in wines.<br>
  • Stabilizer: helps stabilize wine, preventing the formation of turbidity or unwanted deposits.


The peculiarity of Puro 5 is that it is a sulfur dioxide solution that contains no other sources of sulfites, but consists exclusively of sulfur dioxide dissolved in water. This specific formulation is also suitable for use in organic wines intended for export to the United States, where compliance with National Organic Program (NOP) regulations for organic products is required. In other words, Puro 5 can be used in organic wines produced for the U.S. market while meeting the requirements of organic regulations.

Sulfur dioxide in aqueous solution (5%).

Legal limits according to Reg. (EU) 2019/934 expressed as total SO2:

  1. SULFUR DIOXIDE CONTENT OF WINES
    – 150 mg/l for red wines
    – 200 mg/l for white and rosé wines.
  2. SULFUR DIOXIDE CONTENT OF FORTIFIED WINES
    – 150 mg/l if the sugar content is less than 5 g/l
    – 200 mg/l if the sugar content is 5 g/l or more.
  3. SULFUR DIOXIDE CONTENT OF SPARKLING WINES
    – 185 mg/l for all categories of quality sparkling wines
    – 235 mg/l for other sparkling wines.
  4. Legal limits for organic wines: European Regulation 203/2012
    – 100 mg/l for dry red organic wines
    – 150 mg/l for dry white wines.

 

Warning: you are advised to inquire about each state’s limits and restrictions for
possible variations.

Add to the mass taking care to equalize the product by
reassembly or with the use of a venturi tube.

11 kg and 25 kg package.
Store in a cool, dry place and close carefully after use in order to avoid excessive loss of SO2 titer.
