I couldn't find fermcap-s anywhere on this continent. The big homebrew supply sells "Vinoferm Schuimstop (foam stop) / Anti-foam"
Description: Product on a silicone base. Prevents the formation of foam during the distillation process. Totally odourless, tasteless and completely neutral.
No further description given. I wonder if it's the same stuff as fermcap (Dimethylpolysiloxane), does anyone by any slim chance have a clue? Or a wild guess? the only other thing the bottle says is food safe in small quantities, and to add a couple drops per liter. No hint of the compound, and no data sheet. I want to use it to reduce krausen in a foamy ferment.
