Yes, I would ferment 3-5 times the amount you feed out daily, b/c it will take a few days to start to ferment well, then you could feed out your measured amount and still have plenty of fermented grain/water left in the bucket to just add more new grain (and water when needed) and stir in You won't need to add anything extra like acv to the already fermented base, just treat it like sourdough and add new what you use.Really,
lets say 1 cup buckwheat groats to 1/4 cup ACV plus water about 3cups. ????
The buckwheat does not swell up big, just a fraction.
Does that sound right about the ingredient measurements ???
Thanks.
