Spelt Starter — Rehydration & Care
Spelt Sourdough Starter
This guide will walk you through rehydrating your dried spelt sourdough starter and caring for it as it becomes active.
Spelt is an ancient wheat with weaker, more fragile gluten than modern wheat. It ferments readily, often shows activity quickly, and prefers gentle handling. With spelt, the goal is steady fermentation without over-acidifying the culture.
What to Expect
Early activity is common — bubbles may appear within the first 24 hours.
Spelt starters often rise easily but can peak and collapse faster than white starters.
Smells will evolve (floury → lightly sweet → tangy / yeasty).
Because spelt ferments efficiently, it can become acidic if left unfed too long.
Moderate temperatures produce the best balance of flavour and strength.
Most spelt starters are ready to bake in 4–6 days.
What You’ll Need
- Dried spelt sourdough starter (entire packet)
- Spelt flour (recommended)
- Water (warm on Day 1, room temperature after)
- A small jar or container (loosely covered)
- A scale (preferred for accuracy)
Getting Started — Day 1
- Add all of the dried starter to a clean jar
- Add 50 g warm water (not hot)
- Add 50 g spelt flour
- Mix gently until fully combined
- Cover loosely and let rest for 24 hours at 20–24°C (68–75°F)
Day 1 notes:
- The mixture may feel softer than white flour starters
- Avoid over-mixing; gentle incorporation is enough
-
Early bubbles are a good sign but not required
First Feeds — Days 2–4
- Keep 50 g starter (discard the rest)
-
Feed:
-50 g spelt flour
-50 g water
- Mix gently
- Cover loosely and rest 24 hours
Repeat daily.
What you may notice:
- Noticeable rise earlier than white starters
- A mild, slightly sweet aroma
- Faster peak followed by collapse
If the starter smells sharp, it’s usually a sign it’s ready to be fed.
Days 4–7 — Building Strength
By this stage, your spelt starter should be active and responsive. The focus now is maintaining balance, not speed.
Daily Feeding (Days 4–7)
- Keep 50 g starter (discard the rest)
-
Feed:
-50 g spelt flour
-50 g water
- Mix gently
- Cover loosely and rest 24 hours
This maintains a 1:1:1 feeding ratio.
What you should start seeing:
- Reliable rise after feeding
- A peak within 6–10 hours
- A clean, mildly tangy aroma
If it rises very fast and collapses:
- Move to a slightly cooler spot
- Consider a larger feed once active (see ratios below)
When Is It Ready?
Your spelt starter is ready to bake when:
- It rises reliably after feeding
- It peaks predictably without excessive collapse
- It repeats this behaviour for two consecutive feeds
Spelt starters often mature quickly — resist the urge to rush ratio changes.
Ongoing Feeding & Care
Once active, feeding ratios can help manage spelt’s naturally fast fermentation.
All ratios are written as: starter : flour : water
Feeding Ratios — When & Why to Use Them
1:1:1 — Maintenance Feeding
Best for daily care in moderate temperatures.
1:2:2 — Acidity Control / Pre-Bake Feeding
Useful if the starter ferments too quickly or smells sharp.
1:3:3 — Slower Fermentation
Helpful in warm kitchens or if feeding less often.
Rule of thumb:
If spelt ferments too fast, increase the feeding ratio rather than feeding more often.
Always discard before feeding, and feed based on activity, not the clock.
Storage Options
Room Temperature
- Feed once daily
- Best if baking frequently
- Keep loosely covered
Refrigerator
- Feed as usual
- Refrigerate with a loose lid
- Feed once weekly when not baking
Common Questions & Troubleshooting
It rises and collapses quickly
Normal for spelt. Use a larger feeding ratio to slow it down.
It smells sour sooner than expected
A sign of fast fermentation — feed earlier or increase ratio.
Texture feels looser
Normal. Spelt gluten is softer than modern wheat.
Using Your Spelt Starter
Spelt starter works well for:
- Spelt sourdough loaves
- Mixed-grain breads
- Lighter, more extensible doughs
