Where can I get non-chlorinated, non-fluoridated water? I understand that almost no water filters remove fluoride.
Do I need to use that water every time I feed the starter?
You are correct, most basic filters cannot take out fluoride or chloramine, but they can take out chlorine. Specialty filters for certain units can take out fluoride, but your best bet is to buy bottled water: spring water, distilled, or drinking water. Yes, in order to keep your culture alive you must give it pure water to survive every time.
I have a grinder that I grind grain into flour with. Can I use that kind of flour for this? I am new to sourdough so have no idea what it would do. Thanks!
We have found that fresh milled flour does not work well for sourdough starter. It is best to use a flour that has aged for at least 2 months. You can also purchase a flour at the store.
Fresh milled flour can be used for baking with your starter with wonderful results.
The shelf life of our dehydrated sourdough starters are as follows:
At room temperature (68° to 78°F): 12 months
In the refrigerator (40° to 45°F): 12+ months
In the freezer (0° to 25°F): 12+ months
Maximum culturing temperature: 90°F
