COOKING TIPS
In the kitchen.
- 1Pitch yeast at cool temperatures (9°C-13°C) to ensure a clean, crisp lager profile
- 2Perform a 'diacetyl rest' by raising the temperature to 18°C for 48 hours near the end of fermentation
- 3Ensure the wort is thoroughly aerated or oxygenated before pitching to support healthy cell growth
STORAGE
Keep it fresh.
- Store liquid cultures in the refrigerator between 1°C and 4°C (34°F-40°F)
- Keep in a strictly sanitized, airtight container to prevent wild yeast contamination
- Use within the manufacturer's expiration date or within 2-4 weeks if harvested from a previous batch
FAQ
Frequently asked questions.
How long does American lager yeast last in the fridge?
Liquid American lager yeast typically remains viable for 3 to 4 months if kept refrigerated, though viability drops significantly after the first month.
Can I freeze American lager yeast?
Standard freezing will kill the yeast cells. It can only be frozen for long-term storage using a specialized glycerin solution (cryopreservation).
What is the best way to store harvested lager yeast?
Store it in a sanitized glass jar under a layer of beer (to prevent oxidation) in the coldest part of your refrigerator.
How can I tell if the yeast is still good?
The best way is to make a small yeast starter; if you see activity (bubbles/foam) within 24 hours, the yeast is viable.
What can I use as a substitute for American lager yeast?
German Lager yeast (W-34/70) or California Common yeast are the best substitutes for a clean, crisp profile.
Does American lager yeast contain gluten?
The yeast itself is a fungus and gluten-free, but it is often grown on barley-based media. Celiacs should look for certified gluten-free cultures.
What temperature range is best for this yeast?
American lager strains typically perform best between 9°C and 13°C (48°F-55°F) for primary fermentation.
What are the main health benefits of consuming yeast?
It is exceptionally high in B vitamins (B1, B2, B3, B9) and minerals like phosphorus and potassium, supporting nervous system health.
How do I prepare the yeast for brewing?
Remove it from the fridge 3-6 hours before pitching to reach room temperature, or create a yeast starter 24-48 hours in advance.
What flavor profile does American lager yeast produce?
It is known for a very clean, neutral profile with low ester production and low sulfur, allowing malt and hops to shine.
