Strain the contents of the bucket through a wire mesh over a bowl, reserving the juice. Discard the solids. You will end up with about half as much juice as solids. Pour the juice into a measuring cup and note the measure, then pour the juice into a clean plastic bucket. Add flour equal to the amount of grape juice and whisk to create a thick slurry. Cover with a double layer of cheesecloth and let stand at room temperature to naturally ferment for 3 days. The starter, known as a
chef
at this point, will bubble and foam.
On the third day, add the mineral water and 1

cups of flour to the starter, adding a bit more flour if you desire a thicker starter. Whisk until smooth. Re-cover the starter, now a classic
levain
, and let rest at room temperature for 24 hours to 3 days, depending on how sour you want it. (Some bakers pre-ferment sour starter for up to one month at room temperature with occasional feedings.)
At this point, this starter can be stirred down and used immediately. Or cover the starter loosely and store it in the refrigerator for up to 1 week. For information about maintaining your starter, see

Bread Machine Baker’s Hint: Tips for Sourdough Starters
T
his is a light-textured, yet chewy sandwich loaf. Your bacteria-laden starter will give a unique flavor to this old-fashioned American pan bread that will depend on where you live and what wild yeasts your starter has picked up. I make this loaf with the
Next-Day White
or
French Buttermilk
starter. The dough also makes very nice rolls; see the Variation.

Sprinkle with poppy seeds. Let rise until doubled in bulk, about 40 minutes. About midway through this rise, preheat the oven to 400°F. Bake the rolls for 20 to 25 minutes, until they are golden brown. Transfer the rolls from the pan to cool on a rack.
T
his is a nice, easy-to-make sandwich loaf that features the classic combination of sourdough, caraway, and rye flour baked all the way through in the machine. For the best flavor and texture use light rye flour, which is ground from just the endosperm like white wheat flour. This bread is best made with Next-Day Rye Sourdough Starter.
