Still Spirits T500 Copper Saddles 100 grams. These copper saddles can be used in any reflux column that can hold packing material.
Copper is required as a catalyst to remove sulfur dioxide, the cause of sulfur odors post-distillation. Having some copper in the vapor path is essential during distillation and this 100g pack will do the trick for washes up to 6 gallons and 18% ABV.
Cleaning vapor path copper like this is a good idea after your run. This is true especially if this amount is your only copper and no other part of your still or packing is. This keeps it working well as a catalyst.
