This amazing copper waffle helps convert sulfuric flavors that may have developed during your fermentation via catalytic conversion. The catalytic waffle is made from the purest 99.99% copper that is inflated into a foam-like structure to maximize vapor contact and to polish up sulfur contamination.
The copper waffle, directly after a distillation run, needs to be stored in 40-50% alcohol (heads or tails will do) until the next run. When turned brown, the copper waffle can be cleaned by resting it for an hour in some Coca Cola. With proper use, this innovative catalyst will last you for about 100 runs.
Available in 3, 4, 5, 6 or 8 inch.
