How I feed a 7-year-old sourdough starter from the fridge

You do not have to feed a starter every day. Mine is 7 years and 7 months old, and I have never started over.

You do not have to feed it every day.

Same jar. 7 years and 7 months. Mostly in the fridge.

How do I feed it?

Water, then starter, then flour. Mix. Loose lid.

Busy-dad fridge feed: 10 + 25 + 20

• 10 gStarter
• 25 gFlour
• 20 gWater

Wait until it just starts to bubble. Then the fridge.

How long on that feed? 2–3 days, comfortably.

Past that it gets hungry.

Leaving town? Pack the jar and take it with you.

I have done that.

Or leave it in the fridge, but feed it MORE first.

Vacation feed: 10 + 45 + 40

• 10 gStarter
• 45 gFlour
• 40 gWater

Wait for the first bubbles. Fridge. Fine for 2–3 weeks. I have checked.

What to remember

• Fridge feed: 10 g starter + 25 g flour + 20 g water. Good for 2–3 days.
• Vacation feed: 10 g starter + 45 g flour + 40 g water. Good for 2–3 weeks.
