SafAle US-05 is the benchmark American ale yeast from Fermentis — a clean, neutral strain used by more home brewers and small craft breweries worldwide than any other dry yeast. It produces well-balanced beer with very low diacetyl and a crisp, dry finish that lets hop character speak for itself.

Best suited to: American Pale Ale, West Coast IPA, American IPA, American Amber, American Wheat, Cream Ale, Blonde Ale. Versatile enough to work in almost any ale style where a clean fermentation profile is the goal.

Fermentation parameters:

• Temperature: 15–24°C (optimal 18–22°C)
• Attenuation: 73–77%
• Flocculation: Medium
• Alcohol tolerance: up to 11% ABV
• Pitching rate: 50–80g per 100L

Flavour contribution: Exceptionally clean. Minimal ester production. The yeast profile virtually disappears — it does not compete with your hops or malt. Produces a firm foam head and stays in suspension well during active fermentation.

Choose US-05 over S-04 when you want a drier, cleaner finish and your beer style is American rather than English. S-04 leaves more body and drops clearer faster; US-05 ferments more completely and is more neutral.

Pitching note: Sprinkle directly onto wort at fermentation temperature, or rehydrate in 10x its weight in 27°C water for 15 minutes. Rehydration improves cell viability at higher gravities.

Storage: Keep refrigerated. Once opened, reseal and use within 7 days.
