Quick Answer
Which should I use?
Use a liquid (100% hydration) starter for quicker, tangier fermentation and easier mixing. Use a stiff (50โ60% hydration) starter for milder acidity, more lactic character, and easier storage. Both are valid โ choose based on flavor preference, schedule, and recipe needs.

Comparison Table
| Property | Option A | Option B | Significance |
|---|---|---|---|
| Typical hydration | 100% (liquid) | 50โ60% (stiff) | Hydration controls microbial balance and handling |
| Fermentation speed | Faster (more active) | Slower (sluggish peaks) | Liquid starters ferment quicker at same temperature |
| Acidity profile | Higher acetic & acetic-to-lactic ratio (tangier) | More lactic acidity (milder, rounder) | Texture and flavor of crumb and crust change |
| Flavor impact | Bright, complex, sometimes sharp | Gentler, dairy-like lactic notes | Choose based on desired sourness |
| Shelf life / storage | Shorter between feeds at room temp | More stable, dries slower when refrigerated | Stiff starter easier to maintain long-term |
| Handling when mixing dough | Incorporates quickly, acts like a liquid preferment | Requires more kneading/folding and degradation to disperse | Affects dough rheology |
| Measurement & feeding ease | Simple to pour and measure by volume once practiced | Needs scraping โ use a [jar spatula](https://amzn.to/3ND05v5) | Practical kitchen considerations |
| Microbial ecology | Favors faster-growing yeasts and some heterofermentative bacteria | Favors bacteria with slower metabolism and more lactic strains | Different flavor and gas profiles[1][2] |
When to Use Which?
Greater activity shortens proof times and gives reliable peaks[1]
Lower acetic levels and rounder lactic profile produce gentle flavor[2]
Slower activity reduces risk of over-acidification during long retards[1]
Easier incorporation into wet doughs and stronger yeast activity
More stable in the fridge and less prone to rapid acidity swings[2]
Tends to produce sharper acetic notes under similar conditions[1][2]
Can I Mix Both?
Can I use both?
Yes โ many bakers maintain one main starter and convert its hydration for specific recipes. You can feed a stiff starter to leaven a dough as a liquid preferment by discarding and feeding to 100% hydration 6โ12 hours before use. Maintain consistent feeding to avoid stress on the culture.
Converting Between Hydrations
A โ B
Flour: To convert a liquid starter to stiff: reduce water proportionally. For example, convert 100 g at 100% hydration (50 g flour + 50 g water) to ~60%: feed 50 g flour + 30 g water to reach ~60% hydration.
Water: Reduce water by ~20โ40% depending on target hydration
โ Slower peaks, milder acid profile; expect longer resting times
B โ A
Flour: To convert stiff (50โ60%) to 100%: add equal weight of water to the flour weight in the starter (e.g., 60 g flour + 60 g water).
Water: Increase water to reach 100% hydration
โ Faster activity and brighter acidity; watch peak timing closely
๐ก Use a [digital kitchen scale](https://amzn.to/4pUMVHi) for precise conversions and track peak times โ liquid and stiff starters peak at different intervals[1][2]. When trying a conversion for the first time, do a small-scale test (30โ50 g) to observe activity.
