1:4:4 Sourdough Starter Feeding Chart to Make 30g Levain (3g : 13g : 14g)

Balanced mid-ratio baker's math to build 30g of active levain (100% Liquid) for an 10 - 12 hrs ripening window.

Executive Baker's Math Summary (Starter Feeding Ratio × Target Weight)

There are exactly 9 parts in a 1:4:4 feed. At 30 g that is 3.3g per part — 3g of it is the seed culture you already own, 13g is new flour and 14g is water. Expect a 10 - 12 hrs window to full dome at 75°F. The zero-discard version builds 50g (6g / 22g / 22g) so 20g always survives in the jar. Suits 10–11 hour overnight levain build at 74°F.

Balancing Yeast Density & Acidity with a 1:4:4 Ratio (30g Levain Build)

Each gram of the 13g flour portion in a 1:4:4 refresh absorbs roughly half its weight in water once fully hydrated, so the 14g water portion at 100% Liquid sits exactly where the flour becomes a pourable paste rather than a shaggy mass — the consistency you want in a 30g levain.

If your culture is sluggish or smells sharply of vinegar, the ratio is usually not the culprit — the culture is. Two consecutive warm 1:4:4 refreshes, each feeding 13g of fresh flour against 3g of tired seed, strip out accumulated acetic acid and restore yeast vigour faster than any other single intervention.

Zero-Discard Scraping Method for 30g Levain (1:4:4)

  1. Reserve the 20g Jar Remainder (6g): Tip your starter jar and scrape every last gram into a clean vessel — roughly 6g — so nothing is discarded.
  2. Combine the 1:4:4 Feed (22g + 22g): Stir 22g of flour into 6g of seed, then add 22g of room-temperature water until no dry flour remains.
  3. Mark the 50g Target: Level the jar and tape a line at the starting height; the culture should dome well past it within 10 - 12 hrs at 75°F.
  4. Harvest 30g and Return 20g: Pour 30g of peaked sourdough culture into your dough, then scrape the surviving 20g back into the jar and refrigerate at 38°F.

Diagnostic Answers: 1:4:4 (1 4 4) Sourdough Starter Feeding Rati

Why does my 1:4:4 levain smell sour instead of sweet?

Sourness means the seed was over-acidic going in. Feed 13g of fresh flour against 3g of the old starter twice in a row at 78°F and the taint disappears.

Can I still make 30g if I only have 15g of culture?

Feed 15g of seed with 13g flour and 14g water, then treat the resulting 42g of levain as your culture instead.

How much extra should I build so I never run out of starter?

Build 50g in total — 6g starter, 22g flour, 22g water — and the leftover 20g becomes the seed for the next feed.
