Before you can bake that tangy, chewy sourdough loaf, you need this — a living culture of wild yeast and beneficial bacteria that you’ll nurture like a little pet. Once you have it, you have it forever.
What You’ll Need
- 🫙 Wide-mouth quart mason jar — perfect for watching your starter grow

Grandma’s Tip
Name your starter! Mine is called Earl. A named starter is a loved starter, and a loved starter rises beautifully. The wild yeasts from YOUR kitchen make YOUR bread unique to you.
Gut Health Benefits
Sourdough fermentation partially breaks down gluten and phytic acid, making bread more digestible. The lactic acid bacteria produce compounds that act as prebiotics, nourishing your gut microbiome.
Frequently Asked Questions
How long until my starter is ready?
Most starters are ready in 5-7 days, but some take up to 2 weeks. Patience is key!
Why isn’t my starter bubbling?
Temperature is usually the culprit. Keep your starter between 70-78°F. Too cold and the yeast becomes sluggish.
Can I use all-purpose flour?
Yes, but whole wheat or rye flour works faster because they contain more wild yeast on the bran.
