Seasonal Adjustments for 25°C Fermentation

Winter (Cold Kitchen)

Typical kitchen temp: 18-20°C (64-68°F)

Solutions:

  • ✓ Turn on oven light → place dough inside (oven OFF)
  • ✓ Use heating pad on LOW setting under bowl
  • ✓ Place bowl near (not on) radiator
  • ✓ Add +30-60 minutes to rise time

Summer (Hot Kitchen)

Typical kitchen temp: 28-32°C (82-90°F)

Solutions:

  • ✓ Reduce yeast by 20-25%
  • ✓ Use cold water (10-15°C) in dough
  • ✓ Reduce rise time by 30-45 minutes
  • ⚠️ Watch closely - over-proofing risk! Poke test frequently

Don't Have a Thermometer? Measure Room Temperature

✋ Method 1: The Hand Test

Place your hand flat on the counter for 10 seconds:

  • ❄️
    Feels uncomfortably cool

    ~18-20°C (64-68°F) - Too cold, needs warming

  • ✅
    Feels neutral/comfortable

    ~22-25°C (72-77°F) - PERFECT!

  • ⚠️
    Feels slightly warm

    ~26-28°C (79-82°F) - Watch for over-proofing

🍞 Method 2: The Dough Test

Check your dough after 1 hour of rising:

  • 🐌
    Barely risen (10-20%)

    Too cold - Move to warmer spot or wait longer

  • ✅
    Risen 30-50%

    Perfect pace! Continue as planned

  • 🚀
    Risen 80%+ already

    Too warm - Move to cooler spot or shape now

For the same recipe with 1% instant yeast

Fermentation time comparison at different temperatures for the same bread recipe
Temperature Zone Celsius Fahrenheit Bulk Rise Time Flavor Development Best For
Cold Fermentation 4-10°C 39-50°F 12-48 hours ⭐⭐⭐⭐⭐ Maximum Sourdough, pizza, artisan bread
Room Temperature ← YOU ARE HERE 20-25°C 68-77°F 2-3 hours ⭐⭐⭐ Good balance Most recipes, everyday baking
Warm Proofing 28-32°C 82-90°F 1-1.5 hours ⭐⭐ Less complex Quick breads, dinner rolls
Yeast Activation 38-43°C 100-110°F 5-10 minutes N/A Blooming dry/active yeast only

Slower fermentation = better flavor. If you have time, opt for cooler temperatures (18-22°C) and extend rise time by 50%. Your bread will thank you!

Troubleshooting at 25°C (77°F)

🚨 Dough Not Rising

Possible Causes:

  • • Yeast expired or dead
  • • Water was too hot (>43°C kills yeast)
  • • Too much salt (touch yeast directly)
  • • Old flour with no food for yeast

Fix:

Test yeast: Mix with warm water + sugar. If no foam in 10 min, yeast is dead. Buy fresh yeast.

⚠️ Over-Proofed (Collapsed)

Possible Causes:

  • • Left too long (>4 hours at 25°C)
  • • Kitchen warmer than expected
  • • Too much yeast in recipe

Fix:

Punch down gently, reshape, let rise 30-45 min. Reduce yeast by 25% next time.

❓ Unsure If Ready

The Poke Test:

  • • Poke dough gently with finger
  • • Indent springs back slowly → Ready!
  • • Springs back fast → Needs more time
  • • Doesn't spring back → Over-proofed

Visual Cue:

Dough should be puffy, jiggly, and 1.5-2x original size.

Frequently Asked Questions

What is 25°C in Fahrenheit for bread fermentation?

25 degrees Celsius equals 77 degrees Fahrenheit. This is considered the ideal room temperature for bread fermentation, where most bread doughs will double in size within 2-3 hours.

Why is my dough not rising at 25°C?

Common causes include expired yeast, water that was too hot (above 43°C/110°F kills yeast), too much salt in direct contact with yeast, or insufficient sugar/food for the yeast. Test your yeast by mixing it with warm water and a pinch of sugar - it should foam within 10 minutes.

Is 25°C too warm for sourdough fermentation?

No, 25°C (77°F) is perfect for sourdough bulk fermentation. It provides an excellent balance between rise speed and flavor development, typically taking 4-6 hours for bulk fermentation depending on starter strength.

How long does bread take to rise at 25°C?

At 25°C (77°F), most bread doughs with standard yeast amounts will complete bulk fermentation in 2-3 hours. Second rise (proofing) typically takes 45-90 minutes. Times vary based on yeast amount, dough hydration, and recipe specifics.

What happens if my kitchen is warmer than 25°C?

If your kitchen is 28-30°C (82-86°F), reduce yeast by 20-25%, use colder water in your dough, and watch carefully for over-proofing. At warmer temperatures, fermentation speeds up but flavor development decreases. Consider using the refrigerator for slower, more flavorful fermentation.
