Still Spirits Copper Saddles for Reflux
Copper is required as a catalyst to remove sulphur odours during distillation. These are essential for high alcohol washes, typically over 16% ABV.
To wash your saddles, remove them (both ceramic and copper, but keep them separate for ease of reassembly) from the column and soak them in vinegar for a few hours. Once finished, rinse thoroughly with fresh water 3 or 4 times before putting them back in the condenser. You only have to rinse your column and saddles every 5-10 distillations to ensure the sulfur removing properties of the copper saddles are maintained.
