🔥 Mashing Temperatures

Stage Temperature Notes
Strike Water 162°F (72°C) Heat to this before adding grain. Will drop when grain added.
Target Mash Temp 152°F (67°C) Ideal for balanced body/fermentability. Hold for 60 min.
Mash Range (Low) 148-150°F (64-66°C) More fermentable wort → drier, lighter body beer
Mash Range (High) 154-158°F (68-70°C) Less fermentable → sweeter, fuller body beer

♨️ Boiling

Rolling Boil 212°F (100°C) Maintain vigorous boil for 60 minutes. No lid!
⚠️ Boil-Over Warning: Watch carefully when wort first reaches boiling. Reduce heat immediately when foam rises to prevent messy boil-overs.

❄️ Cooling & Pitching

Pitching Temperature <75°F (<24°C) Cool to this BEFORE adding yeast. Ideally 65-70°F.
Danger Zone >90°F (>32°C) Yeast stress/death. Never pitch above this!
⚠️ Hot Wort Kills Yeast! Always verify temperature before pitching. When in doubt, wait longer for cooling.

🧫 Fermentation (US-05 Yeast)

Ideal Range 64-68°F (18-20°C) Cleanest fermentation, balanced esters
Acceptable Range 60-72°F (15-22°C) Will ferment fine, may have more/fewer esters
Too Cold <58°F (<14°C) Yeast may go dormant, sluggish/stuck fermentation
Too Warm >75°F (>24°C) Produces fusel alcohols, harsh flavors
💡 Tip: Fermentation generates heat. Your fermenter may be 2-5°F warmer than the room during active fermentation. Find a cool, stable spot.

🍾 Bottle Conditioning

Conditioning Temp 65-75°F (18-24°C) Room temperature for carbonation (2+ weeks)
Serving/Storage 38-45°F (3-7°C) Refrigerator temp after conditioning complete

🧴 Sanitizer

Star San Solution Room Temp Works at any reasonable temperature
Yeast Rehydration (optional) 95-100°F (35-38°C) If rehydrating dry yeast before pitching
