We don't carry a specific buckwheat starter, but you can use buckwheat with any sourdough starter as long as you activate your starter on the flour the instructions call for and then switch to buckwheat:
I started my culture for the whole wheat sourdough yesterday and used Brita filtered water. Now I read that filters do not remove chloramine... i don’t have any bubbles yet. Is this because I used the wrong water?
Filters do not remove chlorine but you can remove it yourself either by letting the water sit out overnight or boil it before using it in culturing. However, as long as your water doesn't contain abnormally high levels of chlorine, you should be ok. Please contact us at firstname.lastname@example.org to do some troubleshooting if you still see no bubbles after 7 days. It's usually an easy fix!
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.
