Question on Siebel Salts composition, or source:
When I was searching for a good Kolsch recipe, I found the Saint Arnold Fancy Lawnmower clone recipe at https://www.homebrewersassociation.org/homebrew-recipe/saint-arnold-fancy-lawnmower-beer/
, which calls out water salts I am not familiar with - "Siebel Salts".
I cannot find these anywhere on the internet, and certainly not at my local homebrewer supply. The recipe describes the salts contents, but not quantities. The contents are Calcium Sulfate (gypsum), Magnesium Sulfate (Epsom), Magnesium Carbonate (hydrate number?), and Ammonium Carbonate. I am guessing this is to simulate water in the Cologne area, having something to do with Siebel, Kreuztal, Germany, which is near Cologne (aka Köln, the namesake of Kolsch), maybe a creek that's a tributary to the Rhine (goes through Köln), or a local aquifer that's named after nearby Siebel.
Anyone know anything about Siebel salts and their contents?
Thanks to all who respond!
