DAYS 4, 5, 6 — Twice-Daily Feeds Begin

DAYS 4, 5, 6 — Twice-Daily Feeds Begin

This is where the schedule intensifies. From Day 4 through Day 6, feed your starter twice a day, roughly every 12 hours (e.g., 8 AM and 8 PM).

Each feed:

  • Discard all but 75 g
  • Add 50 g whole wheat + 50 g bread flour + 100 g warm water
  • Whisk, scrape, reset rubber band to the new starter level, loose lid, warm spot.

Why twice daily now? The microbial population is exploding. Without more frequent feeds, the culture eats through its food and the yeast goes dormant or the bacteria over-acidify it.

What to look for:

  • By Day 4–5: bubbles forming throughout the jar.
  • By Day 6: visible rise between feedings, sour-yeasty smell (sometimes briefly funky/cheesy — normal, it passes).
