How many minerals can yeast tolerate? I'm going to brew an ale this Summer while working on Mt. Rainier using the mountain's glacial runoff. I don't know the chemistry of the water but it's cloudy with minerals. At some points the water looks identical to skim milk.
What do you think will happen? Will my yeast just die?
You may find somewhere locally that will do it. Maybe the WSU cooperative extension in your area can help. Many folks on here send theirs in to Ward Labs.
