Combine 60g (½ cup) whole wheat flour and 60g (¼ cup) water.

Let rest and don’t do anything to the Sourdough Starter.

Feed the Sourdough Starter each day: Discard the Sourdough Starter until you have 60g of Sourdough Starter remaining to feed. Feed  the Sourdough Starter 60g (½ cup) unbleached all purpose flour or bread flour and 60g (¼ cup) water.

Continue a daily feeding schedule of 1:1:1 by weight ratio of the Sourdough Starter/water/flour if the Sourdough Starter is kept at room temperature.

If the Sourdough Starter is stored in the refrigerator you only need to feed it once a week.

You can build your Sourdough Starter up by neglecting to discard and continuing feed it as long as you continue a 1:1:1 by weight ratio of the Sourdough Starter/water/flour.
