Sourdough Starter

Okay, so we caved!

Everyone's been baking up a storm since we've been stuck in the house and our team at Wave Soda is no different. Instead of fighting it, we decided to give in and do what everyone else is doing.

Yup, I mean making sourdough.

There are as many methods for making sourdough starter as there are bakers. Classicists say flour and water is enough to begin fermentation. Others—like Peter Reinhart of The Bread Baker’s Apprentice, who inspired this recipe—suggest adding fruit juice to kick-start things. Mostly, it’s the environment that matters: Measure liquids to solids carefully, use filtered water, and use room-temperature ingredients to help bacteria and yeast flourish and multiply.


  • 2 cups whole wheat flour
  • 14 cup plus 2 Tbsp. pineapple juice


  1. In a quart-size canning jar or resealable plastic container, add 3½ tablespoons flour and ¼ cup pineapple juice; stir vigorously with chopsticks until combined. Cover with plastic wrap and let rest in a warm spot for 48 hours, opening the jar and stirring again 3 times a day.
  2. Stir in 2 more tablespoons each flour and juice. Cover with plastic wrap and let rest another 48 hours, opening the jar and stirring again with chopsticks 3 times a day. (By the end, you should see some bubbles forming.)
  3. Add 5 tablespoons plus 34 teaspoon flour and 3 tablespoons tepid filtered water; stir vigorously. Cover and let rest 24 hours.
  4. Add ½ cup flour and 13 cup tepid filtered water; stir vigorously. Cover and let rest 24 hours. Repeat again the following day. (Starter should be bubbly, cheesy, and smell like beer.) It is now ready to use or give away.
  5. Feed the starter (or advise your friends to) about 8 hours before using: Begin by discarding all but ½ cup starter from the jar. Add ½ cup tepid filtered water and 1 cup total of flours of your choice (a good standard mix is 20% whole wheat, 80% unbleached white). Mix well, scraping down the sides of the jar. To use every or every other day, keep your starter at room temperature and feed it daily. To use intermittently, store in the fridge and feed once a week.

Hopefully this recipe wasn't too tricky, but don't feel bad if you had to scroll back up and read it a few times, so did we!
