Default Fermentation ScheduleUpdated 10 days ago

Use this schedule when you’re not sure what to select—it's optimized for clean, balanced beers using standard ale yeast. This timeline aligns with how Exobrew automates each stage of fermentation, while still allowing for future fine-tuning.

Phase 1 – Yeast Pitching

Target wort temp: 64–72°F (18–22°C)
When to pitch: Once the cooling phase finishes and the system prompts you

• Pitch healthy yeast into cooled wort

• Make sure the keg lid is sealed and ball locks are connected

• Fermentation begins automatically within 12–24 hours

• 
  

Phase 2 – Active Fermentation

Duration: ~4–6 days
Temp: 68°F (20°C) for most ale yeasts

• You’ll notice pressure buildup and bubbling

• This is where alcohol, CO₂, and flavor compounds are produced

• Exobrew controls temperature for optimal yeast performance

• 
  

Phase 3 – Diacetyl Rest

Duration: 1–2 days (included in the active phase)
Temp: Held at 68–70°F (20–21°C)

• Allows yeast to reabsorb off-flavor compounds like diacetyl

• Happens naturally at the end of primary fermentation

Phase 4 – Conditioning

Start: Once active fermentation is complete
Temp: 41°F (5°C)
Duration: 2–5 days (can go longer if needed)

• Exobrew will cool down the beer.

• Cold temperatures help yeast settle and improve clarity

• Slightly higher temps (up to 46°F / 8°C) are okay—add an extra day or two

Optional – Cold Crash

Temp: 35–39°F (1.5–4°C)
Duration: 1–3 days

• Further improves clarity and helps the trub compact

• Best for clean styles or if bottling/kegging outside the Smart Keg

Total Time: ~7–11 days

(depends on style, temperature, and yeast strain)
