Sourdough Starter Maintenance – The Lazy-but-Reliable System

How Often You Bake
Best Maintenance Method
Feeding Ratio & Schedule
Storage Location
Every day or every other day
Room-temperature starter
Keep 50–100 g → feed 1:2:2 or 1:3:3 once or twice a day (morning + evening if very active)
Counter (18–26 °C)
2–4 times per week
Room-temp during the week, fridge on weekends
Feed 1:3:3 every 12–24 h on baking days → fridge Friday night → take out & feed Sunday evening
Counter most of week
Once a week or less
Fridge method (the easiest)
Keep only 20–50 g in the jar → feed 1:4:4 or 1:5:5 once per week (or whenever you remember)
Fridge door (4–8 °C)
Rarely (once a month or less)
Deep-fridge hibernation
Feed 1:5:5 with rye flour → let rise 4–6 h → fridge. Can survive 4–8 weeks without feeding
Back of fridge


Exact Step-by-Step for the Two Most Popular Methods

Method 1: Weekly Fridge Maintenance (most people use this)

  1. Take the jar out of the fridge (even if it has grey liquid or smells strong– totally normal).
  2. Stir in the hooch (alcohol liquid) or pour it off – both work.
  3. Discard down to 30 g starter (eyeballing is fine).
  4. Add 60 g flour (any mix of white/whole-wheat/rye) + 60 g water (1:2:2).
    → For extra safety use 75 g flour + 75 g water (1:2.5:2.5).
  5. Mix well, mark level with a rubber band, leave on the counter 4–12 hours until at least doubled and domed.
  6. Put straight back in the fridge. Done for the week.

Repeat every 7–14 days. It will stay healthy for months and actually improves with age.

Method 2: Daily Counter Maintenance (for frequent bakers) Keep only 50 g of starter in the jar.
Twice a day (morning + evening):

  • Discard down to 50 g
  • Feed 50 g flour + 50 g water (1:1:1) → ready to bake in 4–6 h
    OR once a day feed 1:3:3 (50 g starter → 150 g flour + 150 g water) → very predictable.

Emergency Revival (if it’s been neglected for months)

  1. Pour off any black liquid.
  2. Take 20 g of the old starter → 40 g rye flour + 50 g warm water.
  3. Feed 1:3:3 with rye for 2–3 days straight → it will come roaring back.

Golden Rules

  • Never let the jar go completely dry.
  • Always keep at least a teaspoon in the jar before feeding.
  • Rye flour wakes sleepy starters up the fastest.
  • Smells like nail polish or vinegar for a day or two after the fridge is normal.
  • If you ever see orange/pink streaks or fuzzy mold → throw it out.

With the weekly fridge method, you literally spend 3 minutes per week and have a happy, vigorous starter forever.
Thousands of bakers have kept the same starter alive for 5–15+ years this way.
Happy baking!
