VASCM: Empty Cooperage Preservation Survey

[David Moore]

 Hi All,The gas suppliers in general cannot sell this product because it is a registered pesticide and they must be licensed pesticide dealers to sell it.  The CDPR registration is active so businesses or individuals with the correct licensing should be able to purchase it, though retailers may be few/far between.  SO2 without the CDPR registration cannot be sold or used for barrel fumigation in CA.
Sulfur wicks are the best alternative in my opinion.

 good old fashion sulfur smoke sticks.  Usually one application every other month.  1 gram per barrel.

Good Afternoon,  I'm curious what winemakers are using for preserving empty cooperage in our area?  We've been using SO2 gas, but I've found that many local gas suppliers (airgas, matheson) are simply refusing to supply it anymore:   
   - Are you using SO2 gas?  If yes, who is your supplier?
   - Are you using Ozone Gas? 
   
   - What type of ozone unit do you use?
   - what is the rate of flow of ozone gas you're using?
   
   - how much time do you spend ozoning each barrel?
   
   - How frequently are you ozone gassing barrels? (once/month, once/week)?
